Sentences with phrase «by brain wave activity»

A brisk morning workout decreases interest in food, as measured by brain wave activity, and doesn't make subjects eat more, according to new research.

Not exact matches

Brain wave activity is both spatial and temporal in nature, and though not directly sensible it is externally detectable by instruments developed and used in physiological psychology.

Intermittent lower - dose exposures can be as toxic as a single higher - dose exposure; Miller cites monkey research showing that either 10 nontoxic weekly doses or one toxic dose of an organophosphate pesticide led to the same increase in brain wave activity as measured by electroencephalogram, or EEG.

By recording neuronal activity in monkeys as they performed tasks that caused saccades, Dr. Christopher Pack has shown that there are waves of activity that cross specific vision processing areas of the brain in defined patterns, and that these patterns are reorganized by saccadic eye movementBy recording neuronal activity in monkeys as they performed tasks that caused saccades, Dr. Christopher Pack has shown that there are waves of activity that cross specific vision processing areas of the brain in defined patterns, and that these patterns are reorganized by saccadic eye movementby saccadic eye movements.

Brown and his colleagues have previously analyzed the electrical waves produced by the brain in different states of activity.

In humans, sleep is also characterized by brain activity: periods of slow - wave activity are each followed by short phases of Rapid - Eye - Movement sleep (REM sleep).

This research by a guy named Marcus Raichle at Washington University School of Medicine in Saint Louis, the reason why he start [ed] to look at it was he began to wonder [whether]-- all this brain wave activity when we look at, when scientists look at brainwave activity, they typically strip out what you and I would call noise.

In their report, Laurent and his colleagues describe the existence of REM and slow - wave sleep in the Australian dragon, with many common features with mammalian sleep: a phase characterized by low frequency / high amplitude average brain activity and rare and bursty neuronal firing (slow - wave sleep); another characterized by awake - like brain activity and rapid eye movements.

By detecting the waves, the scanner can reconstruct the brain as well as detect where neurons are consuming oxygen — a sign of mental activity.

By simulating electrical brain activity and relating the behavior of single neurons to brain waves, the researchers aim to bridge this gap, opening the way to better tools for diagnosing mental disorders, and on a deeper level, offering a better understanding of ourselves.

«Multiple studies have shown that if you take two mammals, say rats, and put them in boxes side by side, then give the first one electric shocks, the reaction of the second one — in terms of brain - wave and nervous - system activity — will be identical,» says Stephen Zawistowski, a certified applied animal behaviorist and an executive vice president of the ASPCA.
