The most rudimentary way to know which areas of the human brain are involved with which functions are through animal experiments (what happens if a certain part of the brain is destroyed or, more mercifully, stimulated?) and through observation of stroke or brain cancer patients (patients who lose function in part of their brain due to lack of blood/...

Agnosia refers to difficulty processing some type of sensory information. Prosopagnosia is just the particular one related to faces, there are many other agnosias caused mainly by brain injury to some specific part of neocortex. There are also aphasias which are difficulties specifically related to speech, or apraxia which is a specific deficit with regards ...

Short answer Excessive Acetylcholine (Ach) release seems to be related Calcitonin Gene-Related Peptide (CGRP) inducing Ach leakage. CGRP is part of a general inflammatory response, in turn part of the pain response associated with trigger points. Background Physiologically spoken, acetylcholine (Ach) is released in the neuromuscular junction by the ...

I believe the procedure described is called either muscle energy technique (MET) or proprioceptive neuromuscular facilitation (PNT). More details are on Advantageceus.com (p. 229). Skin stimuli, like scratching or flicking, may be part of the mentioned techniques. This article on International Journal of Osteopathic Medicine says that "MET application may ...

When you put it that way... "...a cerebral circuit of evil..." ...no, that is absolutely ridiculous (no offense). In the human body (and generally in nature) there are only physical and biochemical mechanisms. All behaviours that are described by the behavioural sciences (e.g. psychology) can be interpreted by biochemical mechanisms. For example, if ...

Stress and excitement both activate the sympathetic nervous system, so they can feel very physically similar (high heart rates, etc.) The main difference is in higher-level brain processing, where stress is subjectively perceived as negative and excitement as positive. Interestingly, there is a study that proposes "anxiety reappraisal" in which you tell ...

The human brain has a specific anatomic site called Nucleus accumbens, that is responsible for reward and reinforcement behavior. The neurotransmitter Dobutamine could be considered as a main molecular mechanism for reward behavior. You can find more information on https://en.wikipedia.org/wiki/Nucleus_accumbens. A stimulus, e.g. eating, can be linked to a ...

Short Answer- Yes, brain activity does cause temperature fluctuations in specific area. robust changes in brain temperature could occur in a temperature-stable environment following exposure to various salient somatosensory stimuli and during different types of motivated behaviors.  1 There are different points of view on why these fluctuations occur ...

A chain of events that leads to release of sensitizing substances, according to Dry needling — peripheral and central considerations (PubMed Central, 2011): ...muscle pain would cause spasm of the same muscle, and in turn would cause more pain leading to more spasms. Sustained contractures of taut bands cause local ischemia and hypoxia in the core ...
