Blood is redirected to the brain and major muscle groups, diverted away from energy consuming bodily functions unrelated to survival at the present time. [11] There are three important axes, the adrenocorticotropic axis, the vasopressin axis and the thyroxine axis, which are responsible for the physiologic response to stress. Cortisol
Multiple hypotheses explain the possible connections between sleep and learning in humans. Research indicates that sleep does more than allow the brain to rest; it may also aid the consolidation of long-term memories. REM sleep and slow-wave sleep play different roles in memory consolidation. REM is associated with the consolidation of ...
The survival of neurons is regulated by survival factors, called trophic factors. The neurotrophic hypothesis was formulated by Victor Hamburger and Rita Levi Montalcini based on studies of the developing nervous system. Victor Hamburger discovered that implanting an extra limb in the developing chick led to an increase in the number of spinal ...
1. Which brain sites can be stimulated to produce the perception of reward? and 2. Which drugs influence the response to stimulation and via what mechanism? [1] Investigation of the brain reward circuitry reveals that it consists of a distributed, multi-synaptic circuit that determines both BSR and natural reward function. [1]
In psychology and cognitive neuroscience, pattern recognition is a cognitive process that matches information from a stimulus with information retrieved from memory. [1]Pattern recognition occurs when information from the environment is received and entered into short-term memory, causing automatic activation of a specific content of long-term memory.
Young woman asleep over study materials. The relationship between sleep and memory has been studied since at least the early 19th century.Memory, the cognitive process of storing and retrieving past experiences, learning and recognition, [1] is a product of brain plasticity, the structural changes within synapses that create associations between stimuli.
SQ had been measured by techniques such as question and answer sessions. These sessions assessed the person's pragmatic abilities to test eligibility in certain special education courses [clarification needed]; however, some tests have been developed to measure social intelligence. This test [specify] can be used to diagnose autism spectrum ...
The explanations generated by the left-brain interpreter may be balanced by right brain systems which follow the constraints of reality to a closer degree. [ 4 ] [ 11 ] The suppression of the right hemisphere by electroconvulsive therapy leaves patients inclined to accept conclusions that are absurd but based on strictly-true logic.
