Another clinical study showed declines in depression, anxiety and suicidal ideation following a treatment program using AVE. [12] A study by Berg and Siever used audio-visual entrainment devices on women with seasonal affective disorder. Both depression and anxiety symptoms were reduced in participants, as compared to a placebo phase.
Although many researchers consider light to be the strongest cue for entrainment, it is not the only factor acting on circadian rhythms. Other factors may enhance or decrease the effectiveness of entrainment. For instance, exercise and other physical activity, when coupled with light exposure, results in a somewhat stronger entrainment response ...
Brainwave entrainment is a colloquialism for 'neural entrainment', [25] which is a term used to denote the way in which the aggregate frequency of oscillations produced by the synchronous electrical activity in ensembles of cortical neurons can adjust to synchronize with the periodic vibration of external stimuli, such as a sustained acoustic ...
Entrainment in the biomusicological sense refers to the synchronization (e.g., foot tapping) of organisms to an external perceived rhythm such as human music and dance. Humans are the only species for which all individuals experience entrainment, although there are documented examples of entrained nonhuman individuals.
A circadian rhythm is an entrainable, endogenous, biological activity that has a period of roughly twenty-four hours. This internal time-keeping mechanism is centralized in the suprachiasmatic nucleus (SCN) of humans, and allows for the internal physiological mechanisms underlying sleep and alertness to become synchronized to external environmental cues, like the light-dark cycle.

Entrainment (hydrodynamics), the movement of one fluid by another; Entrainment (meteorology), a phenomenon of the atmosphere; Entrainment (physical geography), the process by which surface sediment is incorporated into a fluid flow; Entrainment (physics), the process whereby two interacting oscillating systems assume the same period
Some children can tell time on the hour: five o'clock, two o'clock. Knows what a calendar is for. Recognizes and identifies coins; beginning to count and save money. Many children know the alphabet and names of upper- and lowercase letters. Understands the concept of half; can say how many pieces an object has when it has been cut in half.
The K-SADS-PL is used to screen for affective and psychotic disorders as well as other disorders, including, but not limited to Major Depressive Disorder, Mania, Bipolar Disorders, Schizophrenia, Schizoaffective Disorder, Generalized Anxiety, Obsessive Compulsive Disorder, Attention Deficit Hyperactivity Disorder, Conduct Disorder, Anorexia Nervosa, Bulimia, and Post-Traumatic Stress Disorder.
