Sentences with phrase «brain wave activity during»

Not surprisingly, even healthy individuals show significant changes in brain wave activity during brief exposures to olfactory stimuli that are actually below the sensory threshold and not even consciously perceived.

Not exact matches

During REM sleep, the brain generates high - frequency waves of electrical activity and the eyes flicker; in humans, REM is closely linked to dreaming.

Recordings of neural activity in the frontal cortex of the rats showed that, like humans with schizophrenia, these rats also lacked the low frequency burst of brain activity (delta wave) during the timing task.

The current increased the activity of normal beta waves, a kind of brain wave that is usually active during sustained muscle activities, such as holding a book.

The easiest way to determine if someone has temporal lobe epilepsy is to monitor the brain waves during sleep, when there is an increased likelihood of activity indicative of epilepsy.

Slow - wave sleep is also the time when neurons rest and the brain clears away the molecular byproducts of mental activity that accumulate during the day, when the brain is busily thinking and working.

Slow oscillations in brain activity, which occur during so - called slow - wave sleep, are critical for retaining memories.

After the associations between smell and place were well established, the researchers could see a pattern of brain wave activity (the electrical signal from a large number of neurons) during retrieval.

Slumber is known to improve recall in creatures from fruit flies to humans, and the reigning theory among neuroscientists has been that the waves of brain activity during deep sleep reactivate neurons that were triggered during the day, strengthening neuronal connections and cementing them into solid memories.

In addition, during sleep the brain - wave patterns of dogs are similar to people's, and they exhibit the same stages of electrical activity that are observed in humans — all of which is consistent with the idea that dogs are dreaming.

Delta waves were first identified and described in the early 1900s after the invention of the electroencephalogram allowed researchers to look at brain activity during sleep.

Huang and colleagues previously reported that, during sharp - wave ripples in the hippocampus, patterns of brain activity thought to occur during memory replay and consolidation, gamma waves were disrupted in a mouse model of Alzheimer's disease.

Scientists put her in an MRI like a machine, studying her brain waves, and they were, in fact, identical to the overwhelming hurricane of brain activity that occurs during orgasm.

It is called an ambulatory EEG and it is used to monitor brain waves during average day - to - day activities.
