Pharmacological dose response relationships are an application of stimulus-response models. Another field this model can be applied to is psychological problems/disorders such as Tourette syndrome . Research shows Gilles de la Tourette syndrome (GTS) [ 6 ] can be characterized by enhanced cognitive functions related to creating, modifying and ...
Basic models present these effects as additive, with the sum creating the net plastic change (facilitation - depression = net change). However, it has been shown that depression occurs earlier on in the stimulus-response pathway than facilitation, and therefore plays into the expression of facilitation. [11]
An event-related potential (ERP) is the measured brain response that is the direct result of a specific sensory, cognitive, or motor event. [1] More formally, it is any stereotyped electrophysiological response to a stimulus. The study of the brain in this way provides a noninvasive means of evaluating brain functioning.
Functionally, it is highly possible that adaptation may enhance the limited response range of neurons to encode sensory signals with much larger dynamic ranges by shifting the range of stimulus amplitudes. [2] Also, in neural adaptation there is a sense of returning to baseline from a stimulated response. [3]
The stimulus–response model emphasizes the relation between stimulus and behavior rather than an animal's internal processes (i.e., in the nervous system). [2] In experimental psychology, a stimulus is the event or object to which a response is measured. Thus, not everything that is presented to participants qualifies as stimulus.
The mesolimbic pathway and a specific set of the pathway's output neurons (e.g. D1-type medium spiny neurons within the nucleus accumbens) play a central role in the neurobiology of addiction. [20] [21] [22] Drug addiction is an illness caused by habitual substance use that induces chemical changes in the brain's circuitry. [23]
