Sentences with phrase «neural activity seen»

The resulting pattern mimics the abnormal neural activity seen in anxiety disorders.

Recent studies have found that patterns of neural activity seen when an animal is learning a new task are replayed later during sleep.

Not exact matches

Also there is evidence of molecular mechanisms in the cell membranes that can amplify small changes in the field to produce large changes in neural activity.13 On the other hand, earlier tests of Kohler's theory found that interference with electrical gradients over the cortex had no effect on behavioral measures (see note 11 for reference to these studies).

To truly see how neural activity changes during learning, we need to look bigger — at populations of neurons, rather than one neuron at a time, which has been the standard approach to date.

He was paralyzed, but the moment he thought about using his hand, we saw changes in neural activity in the specific part of the motor cortex associated with hand movement.

«When we look at the neural processes that take place in the brain while processing the symbols, we see that around 400 milliseconds after the presentation of the to - be-counted symbol, there is an extreme reduction in brain activity, although it should normally be very high,» explains Schmidt.

Using electroencephalography (EEG)-- in which electrodes placed in the brain measure neural activity — the team saw a sharp wave of action in the mouse brains from the hippocampus in the midbrain to the neocortex (the outermost brain layer).

Brain scans revealed activity in the fusiform face area, responsible for recognising real faces, they report in «Seeing Jesus in Toast: Neural and behavioral correlates of face pareidolia» (doi.org/vn8).

Using imaging techniques, the researchers were even able to detect neural activity (see video, above), although this doesn't mean the brain is conscious in anyway.

The new technique, called Calcium and Light - Induced Gene Handling Toolkit or «Cal - Light,» allows researchers to observe and manipulate the neural activities underlying behavior with never - before - seen specificity, hopefully allowing researchers to identify causality between neuronal activity and behavior.

The only difference in that case is that the neural activity is weaker and delayed in comparison to what happens when an observer consciously registers and can recall having seen a particular image.

We can also couple that with microfluidics to administer neuromodulators, hormones and other molecules and see how site - selective administration of the chemicals modifies neural activity.

Optogenetics, the use of light to control neural activity, is a powerful technique that has seen widespread use in neuroscience research.

Traditionally, it was thought that the there were three main factors that derived from CNS activity that subsequently affected EMG amplitude: the motor unit recruitment extent, the motor unit firing frequency, and the synchronisation of these electrical impulses (with greater synchronisation perhaps implying greater neural drive from the CNS)(see review by Behm, 1995).

Given the role of serotonergic neurotransmission in cognitive control and impulsivity (Gorwood et al. 2000; Mann et al. 2001; Purselle and Nemeroff 2003; Retz et al. 2004; Strobel et al. 2007; Walderhaug et al. 2007; see, however, Clark et al. 2005 for negative evidence), the current findings of greater error - evoked thalamic activity in women seem to indicate a potentially useful intermediate neural phenotype to further elucidate gender differences in depression.
