The medical literature also includes case reports of the recovery of a small number of patients following the removal of assisted respiration with cold oxygen. [18] The researchers found that in many nursing homes and hospitals unheated oxygen is given to non-responsive patients via tracheal intubation.
Habituation is a form of non-associative learning in which an organism’s non-reinforced response to a stimulus decreases after repeated or prolonged presentations of that stimulus. [1] For example, organisms may habituate to repeated sudden loud noises when they learn that these have no consequences. [2]
In physiology, the all-or-none law (sometimes the all-or-none principle or all-or-nothing law) is the principle that if a single nerve fibre is stimulated, it will always give a maximal response and produce an electrical impulse of a single amplitude. If the intensity or duration of the stimulus is increased, the height of the impulse will ...
The term "psychobiology" has been used in a variety of contexts, emphasizing the importance of biology, which is the discipline that studies organic, neural and cellular modifications in behavior, plasticity in neuroscience, and biological diseases in all aspects, in addition, biology focuses and analyzes behavior and all the subjects it is ...
[2] [page needed] Unlike other subdivisions within biological psychology, the main focus of psychological research is the development of theories that describe brain-behavior relationships. Physiological psychology studies many topics relating to the body's response to a behavior or activity in an organism. [3]
Biological psychiatry or biopsychiatry is an approach to psychiatry that aims to understand mental disorder in terms of the biological function of the nervous system.It is interdisciplinary in its approach and draws on sciences such as neuroscience, psychopharmacology, biochemistry, genetics, epigenetics and physiology to investigate the biological bases of behavior and psychopathology.
Inadequate response has most commonly been defined as less than 25% reduction in depressive symptoms following treatment with an antidepressant. [2] Many clinicians and researchers question the construct validity and clinical utility of treatment-resistant depression as currently conceptualized. [3] [4]
Because minimally conscious state is a relatively new criterion for diagnosis, there are very few functional imaging studies of patients with this condition. Preliminary data has shown that overall cerebral metabolism is less than in those with conscious awareness (20–40% of normal [3]) and is slightly higher but comparable to those in vegetative states.
