In a choice reaction time task which calls for a single response to several different signals, four distinct processes are thought to occur in sequence: First, the sensory qualities of the stimuli are received by the sensory organs and transmitted to the brain; second, the signal is identified, processed, and reasoned by the individual; third ...
Improvement to cognitive performance caused by exercise could last for 24 hours, a new study shows. Scientists also linked getting 6 or more hours of sleep to better memory test scores the next day.
Time perception is typically categorized in three distinct ranges, because different ranges of duration are processed in different areas of the brain: [5] Sub-second timing or millisecond timing; Interval timing or seconds-to-minutes timing; Circadian timing; There are many theories and computational models for time perception mechanisms in the ...
The term psychological refractory period (PRP) refers to the period of time during which the response to a second stimulus is significantly slowed because a first stimulus is still being processed. [1] This delay in response time when one is required to divide attention can exhibit a negative effect that is evident in many fields of study.
Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...
“Limbic” is related to the brain areas first involved, “age-related” and the name “LATE” itself refer to the onset of disease usually in persons aged 80 or older. “TDP-43” indicates the aberrant mis-folded protein (or proteinopathy) deposits in the brain that characterize LATE, and “encephalopathy” means illness of brain.

The haemodynamic response is rapid delivery of blood to active neuronal tissue. Complications in this response arise in acute coronary syndromes and pulmonary arterial hypertension. These complications lead to a change in the regulation of blood flow to the brain, and in turn the amount of glucose and oxygen that is supplied to neurons, which ...
