Circadian Rhythms - National Institute of Mental Health (NIMH) Circadian Rhythms are endogenous self-sustaining oscillations that organize the timing of biological systems to optimize physiology and behavior, and health Circadian Rhythms: Are synchronized by recurring environmental cues; Anticipate the external environment;
Section on Light and Circadian Rhythms (SLCR) - NIMH We have shown that ipRGCs target many visual centers in the brain including the circadian pacemaker and the area responsible for pupil constriction, among many others, and are critical for the influence of light on circadian rhythms, sleep, mood and pupil constriction
Samer Hattar - National Institute of Mental Health (NIMH) In 2017 Dr Hattar joined the faculty of the Intramural Research Program at the National Institute of Mental Health His research focuses on light effects on circadian rhythms, sleep, mood and learning
Arousal and Regulatory Systems - National Institute of Mental . . . - NIMH Arousal Regulatory Systems are responsible for generating activation of neural systems as appropriate for various contexts, and providing appropriate homeostatic regulation of such systems as energy balance and sleep 8:30 a m – 5 p m ET, M-F
Cell Networking Keeps Brain’s Master Clock Ticking Each day, a master clock in the brain synchronizes the timing of lesser clocks in cells throughout the body to the rising and setting of the sun, regulating such daily rhythms as sleep, body temperature, eating, and activity
Understanding and Modifying Temporal Dynamics of Coordinated . . . - NIMH Understanding and Modifying Temporal Dynamics of Coordinated Neural Activity The proximal goal of this concept is to test whether modifying specific temporal patterns of coordinated neural activity in vivo can improve cognitive, social, or affective processes
