Sentences with phrase «observe neural activity»

Studying how animals plan over these different timescales has been challenging, in large part because it requires many brain areas operating at once, and neuroscientists have lacked the tools to observe neural activity over broad swaths of the brain.

fMRI is a medical imaging technique which, when applied to the brain allows us to non-invasively observe neural activity associated with specific human behaviour.

She went to work setting up a new series of fMRI studies for observing neural activity in the visual cortex of awake macaque monkeys.

In order to determine what factors are associated with firing rate changes, we generated a prediction of neural activity by convolving observed neural activity aligned with one saccade direction with the intersaccade distribution times aligned with the other saccade direction.

Although Dulac's and Anderson's teams examined different brain regions, both researchers observed a similar relationship between sex - specific neural activity and social behavior.

A team of researchers from the Department of Evolutionary Neuroethology, led by Sonja Bisch - Knaden, has investigated whether neural activity patterns linked to either feeding or egg - laying behavior can already be observed in the antennal lobe, which is the first processing level of scents in the insect brain.

After analysis, the researchers were able to observe how the patterns of neural activity were changing at each stage of each task.

Again, Nrf2 - related activity was observed only when astrocytes were present in cultures, but significantly, Nrf2 signaling increased in tandem with neuronal firing, suggesting that neurons calibrate Nrf2 activity in astrocytes to keep pace with neural activity.

But until recently, there was no way to observe this phenomenon in the neural activity of the brain.

Laureys had observed a signature of coordinated neural activity, present in the resting patient, which seems to appear in the brain of anyone who is conscious.

They observe spot - like neural activity in the dorsal part of the fish telencephalon, which corresponds to the human cortex, upon presentation of the red LED 24 hours after the training session.

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.

Furthermore, we asked what kind of sensory information induces the pattern of neural activity observed during defensive bee ball formation and found that it may relate to the processing of thermal information.

This result, however, might not necessarily mean that IAA plays no significant role in this defensive behavior because the Acks induction was not clearly observed in the ALs of the Japanese honeybee workers even after the seizure - induction, suggesting that Acks might not be applicable for detection of neural activity in the ALs (data not shown).

Quantitative RT - PCR using RNAs extracted from brain, thorax and abdomen of workers revealed that statistically significant and prominent Acks induction was observed only in the brain when the bees were exposed to high temperature, and scarce Acks expression was detected in the thorax and abdomen under both room and high temperatures (Figure 5O), further supporting that Acks induction under a high temperature reflects neural activity and does not result from some «heat shock responses» that could occur independently of neural activity.

In addition, workers exposed to 46 °C heat also exhibited Acks expression patterns similar to those observed in the brains of workers involved in the formation of a hot defensive bee ball, suggesting that the neural activity observed in the brains of workers involved in the hot defensive bee ball mainly reflects thermal stimuli processing.

In these experiments, the researchers were able to activate groups of neurons and then observe the resulting patterns of neural activity.

In part, this is because of the technical hurdles in observing the activity of those 100,000 neurons all at once and at the speed of neural processing.

While these internal neural processes are being observed, the researchers learn more about how the neural system operates through a method called perturbation, which is intentionally disrupting the dynamical neural system in precise ways in order to better understand the underlying principles that control its activity.

At the neural level, Experiment 2 further showed that oxytocin enhanced the originally - diminished social minus belief activity in the right anterior insula in individuals with ASD, but such effect was not observed in the belief minus control activity.

This is further compounded by elevations in metabolic efficiency (whereby energy expenditure declines beyond that predicted from the change in metabolic mass) and appetite which accompany weight - loss, and may ultimately predispose to weight re - gain.82 Moreover, changes in neural activity within brain regions known to be involved in regulatory, emotional and cognitive control of food intake have also been observed following weight - loss.83
