Sentences with phrase «corollary discharges»

To see if the thalamus is the source of corollary discharges, they injected a small part of it with a compound that blocks neuron firing.

Researchers believe the brain solves this problem through a process called corollary discharge.

So, when the UI researchers noticed an increase in brain activity while the newborn rats were twitching during REM sleep but not when the animals were awake and moving, they conducted several follow - up experiments to determine whether sleep twitching is a unique self - generated movement that is processed as if it lacks corollary discharge.

First introduced by researchers in 1950, corollary discharge is a split - second message sent to the brain that allows animals — including rats, crickets, humans and more — to recognize and filter out sensations generated from their own actions.

«But what surprised us even more,» Blumberg says, «was that corollary discharge appears to be suspended during sleep in association with twitching, a possibility that — to our knowledge — has never before been entertained.»

The experiments were consistent in supporting the idea that sensations arising from twitches are not filtered: And without the filtering provided by corollary discharge, the sensations generated by twitching limbs are free to activate the brain and teach the newborn brain about the structure and function of the limbs.
