Some substances may alter functioning in the HPA axis, the neuroendocrine system that mediates responses to stress, where dysfunction has been linked to anxiety and panic disorders. [ 2 ] Some substances, such as caffeine [ 3 ] and sodium lactate , [ 4 ] are largely reported to have anxiogenic effects only if they are consumed or taken by ...
While neurochemistry as a recognized science is relatively new, the idea behind neurochemistry has been around since the 18th century.

[ 7 ] [ 8 ] Chronic stress, and a lack of coping resources available, or used by an individual, can often lead to the development of psychological issues ...
Molecular neuropharmacology involves the study of neurons and their neurochemical interactions, and receptors on neurons, with the goal of developing new drugs that will treat neurological disorders such as pain, neurodegenerative diseases, and psychological disorders (also known in this case as neuropsychopharmacology).
Psychophysiology measures exist in multiple domains; reports, electrophysiological studies, studies in neurochemistry, neuroimaging and behavioral methods. [5] Evaluative reports involve participant introspection and self-ratings of internal psychological states or physiological sensations, such as self-report of arousal levels on the self-assessment manikin, [6] or measures of interoceptive ...
