Neurology in the context of Intravital microscopy

Hippocrates of Kos (/hɪˈpɒkrətiːz/; Ancient Greek: Ἱπποκράτης ὁ Κῷος, romanized: Hippokrátēs ho Kôios; c. 460 – c. 370 BC), also known as Hippocrates II, was a Greek physician and philosopher of the classical period who is considered one of the most outstanding figures in the history of medicine. He is traditionally referred to as the "Father of Medicine" in recognition of his lasting contributions to the field, such as the use of prognosis and clinical observation, the systematic categorization of diseases, and the (however misguided) formulation of humoral theory. His studies set out the basic ideas of modern-day specialties, including surgery, urology, neurology, acute medicine and orthopedics. The Hippocratic school of medicine revolutionized ancient Greek medicine, establishing it as a discipline distinct from other fields with which it had traditionally been associated (theurgy and philosophy), thus establishing medicine as a profession.

However, the achievements of the writers of the Hippocratic Corpus, the practitioners of Hippocratic medicine, and the actions of Hippocrates himself were often conflated; thus very little is known about what Hippocrates actually thought, wrote, and did. Hippocrates is commonly portrayed as the paragon of the ancient physician and credited with coining the Hippocratic Oath, which is still relevant and in use today. He is also credited with greatly advancing the systematic study of clinical medicine, summing up the medical knowledge of previous schools, and prescribing practices for physicians through the Hippocratic Corpus and other works.

Aelius Galenus or Claudius Galenus (Greek: Κλαύδιος Γαληνός; September 129 – c. 216 AD), often anglicized as Galen (/ˈɡeɪlən/) or Galen of Pergamon, was a Roman and Greek physician, surgeon, and philosopher. Considered to be one of the most accomplished of all medical researchers of antiquity, Galen influenced the development of various scientific disciplines, including anatomy, physiology, pathology, pharmacology, and neurology, as well as philosophy and logic.

The son of Aelius Nicon, a wealthy Greek architect with scholarly interests, Galen received a comprehensive education that prepared him for a successful career as a physician and philosopher. Born in the ancient city of Pergamon (present-day Bergama, Turkey), Galen traveled extensively, exposing himself to a wide variety of medical theories and discoveries before settling in Rome, where he served prominent members of Roman society and eventually was given the position of personal physician to several emperors.

In philosophy, the self is an individual's own being, knowledge, and values, and the relationship between these attributes.

The first-person perspective distinguishes selfhood from personal identity. Whereas "identity" is (literally) sameness and may involve categorization and labeling,selfhood implies a first-person perspective and suggests potential uniqueness. Conversely, "person" is used as a third-person reference. Personal identity can be impaired in late-stage Alzheimer's disease and in other neurodegenerative diseases. Finally, the self is distinguishable from "others". Including the distinction between sameness and otherness, the self versus other is a research topic in contemporary philosophy and contemporary phenomenology (see also psychological phenomenology), psychology, psychiatry, neurology, and neuroscience.

A mental state, or a mental property, is a state of mind of a person. Mental states comprise a diverse class, including perception, pain/pleasure experience, belief, desire, intention, emotion, and memory. There is controversy concerning the exact definition of the term. According to epistemic approaches, the essential mark of mental states is that their subject has privileged epistemic access while others can only infer their existence from outward signs. Consciousness-based approaches hold that all mental states are either conscious themselves or stand in the right relation to conscious states. Intentionality-based approaches, on the other hand, see the power of minds to refer to objects and represent the world as the mark of the mental. According to functionalist approaches, mental states are defined in terms of their role in the causal network independent of their intrinsic properties. Some philosophers deny all the aforementioned approaches by holding that the term "mental" refers to a cluster of loosely related ideas without an underlying unifying feature shared by all. Various overlapping classifications of mental states have been proposed. Important distinctions group mental phenomena together according to whether they are sensory, propositional, intentional, conscious or occurrent. Sensory states involve sense impressions like visual perceptions or bodily pains. Propositional attitudes, like beliefs and desires, are relations a subject has to a proposition. The characteristic of intentional states is that they refer to or are about objects or states of affairs. Conscious states are part of the phenomenal experience while occurrent states are causally efficacious within the owner's mind, with or without consciousness. An influential classification of mental states is due to Franz Brentano, who argues that there are only three basic kinds: presentations, judgments, and phenomena of love and hate.

Mental states are usually contrasted with physical or material aspects. For (non-eliminative) physicalists, they are a kind of high-level property that can be understood in terms of fine-grained neural activity. Property dualists, on the other hand, claim that no such reductive explanation is possible. Eliminativists may reject the existence of mental properties, or at least of those corresponding to folk psychological categories such as thought and memory. Mental states play an important role in various fields, including philosophy of mind, epistemology and cognitive science. In psychology, the term is used not just to refer to the individual mental states listed above but also to a more global assessment of a person's mental health.

Ibn Rushd (14 April 1126 – 11 December 1198), Latinized as Averroes, was an Andalusian polymath and jurist who was proficient in a variety of intellectual fields, including philosophy, theology, medicine, astronomy, physics, psychology, mathematics, neurology, Islamic jurisprudence and law, and linguistics. The author of more than 100 books and treatises, his philosophical works include numerous commentaries on Aristotle, for which he was known in the Western world as "The Commentator" and "Father of Rationalism".

Averroes was a strong proponent of Aristotelianism; he attempted to restore what he considered the original teachings of Aristotle and opposed the Neoplatonist tendencies of earlier Muslim thinkers, such as al-Farabi and Avicenna. He also defended the pursuit of philosophy against criticism by Ash'ari theologians such as Al-Ghazali. Averroes argued that philosophy was permissible in Islam and even compulsory among certain elites. He also argued scriptural text should be interpreted allegorically if it appeared to contradict conclusions reached by reason and philosophy. In Islamic jurisprudence, he wrote the Bidāyat al-Mujtahid on the differences between Islamic schools of law and the principles that caused their differences. In medicine, he proposed a new theory of stroke, described the signs and symptoms of Parkinson's disease for the first time, and might have been the first to identify the retina as the part of the eye responsible for sensing light. His medical book Al-Kulliyat fi al-Tibb, translated into Latin and known as the Colliget, became a textbook in Europe for centuries.

Neuropsychology is a branch of psychology concerned with how a person's cognition and behavior are related to the brain and the rest of the nervous system. Professionals in this branch of psychology focus on how injuries or illnesses of the brain affect cognitive and behavioral functions.

It is both an experimental and clinical field of patient-focused psychology. Thus aiming to understand how behavior and cognition are influenced by brain function. It is also concerned with the diagnosis and treatment of behavioral and cognitive effects of neurological disorders. Whereas classical neurology focuses on the pathology of the nervous system and classical psychology is largely divorced from it, neuropsychology seeks to discover how the brain correlates with the mind through the study of neurological patients. It thus shares concepts and concerns with neuropsychiatry and with behavioral neurology in general. The term neuropsychology has been applied to lesion studies in humans and animals. It has also been applied in efforts to record electrical activity from individual cells (or groups of cells) in higher primates (including some studies of human patients).

Psychoanalysis is a set of theories and techniques of research to discover unconscious processes and their influence on conscious thought, emotion and behavior. Based on dream interpretation, psychoanalysis is also a talk therapy method for treating mental disorders. Established in the early 1890s by Sigmund Freud, it takes into account Darwin's theory of evolution, neurology findings, ethnology reports, and, in some respects, the clinical research of his mentor Josef Breuer. Freud developed and refined the theory and practice of psychoanalysis until his death in 1939. In an encyclopedic article, he identified its four cornerstones: "the assumption that there are unconscious mental processes, the recognition of the theory of repression and resistance, the appreciation of the importance of sexuality and of the Oedipus complex."

Freud's earlier colleagues Alfred Adler and Carl Jung soon developed their own methods (individual and analytical psychology); he criticized these concepts, stating that they were not forms of psychoanalysis. After the author's death, neo-Freudian thinkers like Erich Fromm, Karen Horney and Harry Stack Sullivan created some subfields. Jacques Lacan, whose work is often referred to as Return to Freud, described his metapsychology as a technical elaboration of the three-instance model of the psyche and examined the language-like structure of the unconscious.

Neuropathology is the study of disease of nervous system tissue, usually in the form of either small surgical biopsies or whole-body autopsies. Neuropathologists usually work in a department of anatomic pathology, but work closely with the clinical disciplines of neurology, and neurosurgery, which often depend on neuropathology for a diagnosis. Neuropathology also relates to forensic pathology because brain disease or brain injury can be related to cause of death. Neuropathology should not be confused with neuropathy, which refers to disorders of the nerves themselves (usually in the peripheral nervous system) rather than the tissues. In neuropathology, the branches of the specializations of nervous system as well as the tissues come together into one field of study.

Psychoanalytic theory is the theory of the innate structure of the human soul and the dynamics of personality development relating to the practice of psychoanalysis, a method of research and for treating of mental disorders (psychopathology). Laid out by Sigmund Freud in the late 19th century (s. The Interpretation of Dreams), he developed the theory and practice of psychoanalysis until his death in 1939. Since then, it has been further refined, also divided into various sub-areas, but independent of this, Freuds structural distinction of the soul into three functionally interlocking instances has been largely retained.

Psychoanalysis with its theoretical core came to full prominence in the last third of the twentieth century, as part of the flow of critical discourse regarding psychological treatments in the 1970s. Freud himself had ceased his physiological research of the neural brain organization in 1906 (cf. history). shifting his focus to psychology and the treatment of mental health issues by using free associations and the phenomenon of transference. Psychoanalysis is based on the distinction between unconscious and conscious processes, and emphasized the recognition of childhood events that influence the mental functioning of adults. Freud's consideration of human evolutionary history (genetics) and then the aspect of individual psychological development in cultural contexts gave the psychoanalytic theory its characteristics.

Voluntary action is an anticipated goal-oriented movement. The concept of voluntary action arises in many areas of study, including cognitive psychology, operant conditioning, philosophy, neurology, criminology, and others. Additionally, voluntary action has various meanings depending on the context in which it is used. For example, operant psychology uses the term to refer to the actions that are modifiable by their consequences. A more cognitive account may refer to voluntary action as involving the identification of a desired outcome together with the action necessary to achieve that outcome. Voluntary action is often associated with consciousness and will. For example, Psychologist Charles Nuckolls holds that we control our voluntary behavior, and that it is not known how we come to plan what actions will be executed. Many psychologists, notably Tolman, apply the concept of voluntary action to both animal and human behavior, raising the issue of animal consciousness and its role in voluntary action.

Near-infrared spectroscopy (NIRS) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum (from 780 nm to 2500 nm). Typical applications include medical and physiological diagnostics and research including blood sugar, pulse oximetry, functional neuroimaging, sports medicine, elite sports training, ergonomics, rehabilitation, neonatal research, brain computer interface, urology (bladder contraction), and neurology (neurovascular coupling). There are also applications in other areas as well such as pharmaceutical, food and agrochemical quality control, atmospheric chemistry, combustion propagation.

Physical therapy (PT), also known as physiotherapy, is a healthcare profession, as well as the care provided by physical therapists. It focuses on promoting, maintaining, or restoring health through patient education, physical interventions, disease prevention, and health promotion. The term physical therapist or physiotherapist is used to represent the trained person providing physical therapy.

The profession has many specialties including musculoskeletal, orthopedics, cardiopulmonary, neurology, endocrinology, sports medicine, geriatrics, pediatrics, women's health, wound care and electromyography. PTs practice in many settings, both public and private.

Musicology is the academic, research-based study of music, as opposed to musical composition or performance. Musicology research combines and intersects with many fields, including psychology, sociology, acoustics, neurology, natural sciences, formal sciences and computer science.

Musicology is traditionally divided into three branches: music history, systematic musicology, and ethnomusicology. Historical musicologists study the history of musical traditions, the origins of works, and the biographies of composers. Ethnomusicologists draw from anthropology (particularly field research) to understand how and why people make music. Systematic musicology includes music theory, aesthetics, pedagogy, musical acoustics, the science and technology of musical instruments, and the musical implications of physiology, psychology, sociology, philosophy and computing. Cognitive musicology is the set of phenomena surrounding the cognitive modeling of music. When musicologists carry out research using computers, their research often falls under the field of computational musicology. Music therapy is a specialized form of applied musicology which is sometimes considered more closely affiliated with health fields, and other times regarded as part of musicology proper.

A surgical technologist (also called a surg tech, scrub, scrub tech, surgical technician, operating department practitioner or operating room technician) is an allied health professional working as a part of the team delivering surgical care. Surgical technologists are members of the surgical team, which include the surgeon, surgeon's assistant, scrub nurse, circulating nurse and anesthesia provider (anesthesiologist, anesthesiologist assistant or nurse anesthetist). They possess knowledge and skills in sterile and aseptic techniques. There are few mandatory professional requirements for surgical technologists, and the scope of practice varies widely across countries and jurisdictions. Surgical technologists attend junior colleges and technical schools, and many are trained in military schools. In the military they perform the duties of both the circulator and the scrub. The goal is for surgical technologists to be able to anticipate the next move the surgeon is going to make in order to make the procedure as smooth and efficient as possible.They do this by having knowledge of hundreds of surgical procedures and the steps the surgeon needs to take in order to complete the procedure, including the very wide range of surgical instruments they may need. Specialties can include, but are not limited to, the following: genitourinary, obstetrics and gynaecology, urology, ENT, plastics, general, orthopedics, neurology, and cardiovascular. They only work in surgical or perioperative areas and are highly specialized. Surgical technologist is the proper term for a two-year program which earns a degree in applied sciences. The profession is up and coming and highly in demand.
