Sentences with phrase «electrical activity between»

Prior to the study, scientists had observed synchronous patterns of electrical activity between the two circuit hubs after a monkey saw an object, but weren't sure if the signals actually represent such short - term visual memories in the brain.

That defect, which affects electrical activity between cells, occurs in both heart and brain cells.

The pattern of electrical activity between electrodes inside the cortical compartment was relatively unaffected, suggesting the interconnectivity between the cortical neurons was unchanged.

Not exact matches

14 Technical details are not too relevant here, but I want to mention briefly that it is unlikely that one would find gross dissociations between the electrical activities in the field and in the neurons because an autonomous change in the field should cause a corresponding change in the neurons.

The main problem is that it is extremely difficult to measure electrical activity deep inside the brain of a living person, and differences between the brains of living people and those of the animals and cadavers that previous studies have used are significant.

Synapses, junctions between neurons in the brain, display electrical behaviour that depends on past activity and are said to behave like memristors.

Plaque hinders neuronal activity by gumming up synapses (spaces between cells through which chemical or electrical information is transmitted), eventually damaging nerve cell branches and leading to neuronal death.

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.

Like an EEG machine, they could easily distinguish between two phases of sleep in napping newborns: «active» sleep, in which the brain displays continuous electrical activity; and «quiet» sleep, in which brain activity waxes and wanes.

His work suggests that deep - brain stimulation — whether electrical or optical — may be most effective when it targets not the neurons themselves but the connections between cells, thereby affecting the flow of activity between brain regions.

Massimini and his colleagues record the brain's «echo» with electroencephalography, a measure of electrical activity, and then turn that data into a numerical score between 0 and 1.

It may be premature to suggest a direct link between pollution and electrical destruction, but keeping an eye on increased lightning activity could be helpful to those working on preventive measures

The team, led by Alejandro Pérez, Manuel Carreiras and Jon Andoni Duñabeitia, has confirmed by recording cerebral electrical activity - that the neuronal activity of two people involved in an act of communication «synchronize» in order to allow for a «connection» between both subjects.

Monkeys typically find other monkeys impossible to ignore, and this experiment was no exception: the monkeys often failed at the reward task because they looked at the faces, especially if the faces depicted emotion.When humans are torn between paying attention to two different things, it triggers a «conflict» circuit in a brain region called the dorsal anterior cingulate cortex (dACC) which is part of a larger brain structure controlling rational thought and emotions.Using a tiny sensor implanted in the dACCs of the monkeys, Platt's group was able to measure the electrical activity of single neurons.

In laboratory research, rodent models of seizure activity, typically differentiate between absence seizures (a type of generalized epilepsy, in which electrical activity of the entire brain is affected), and mesial temporal lobe epilepsy (a type of partial epilepsy, which only affects one hemisphere of the brain).

The size of the LGN layers, and the connectivity between neurons within the layers, depended on the intensity of the spontaneous electrical activity.

But once the animals had learned the best route, the firing pattern was starkly different: high - level electrical activity appeared as the animals entered the maze, and when they ate their reward, but in between — while following the now - learned route in a more automatic fashion — neuronal activity was much lower.

Among these achievements are the development of new techniques for classifying different types of neurons; automated methods for creating wiring diagrams of the connections between cells in the mammalian brain; new ways of recording and manipulating the electrical activity of hundreds, even thousands, of cells simultaneously; and, advanced microscopes that allow researchers to visualize the activity of all the cells in the brains of small animals.

It stabilizes correct fluid volume in the bloodstream and aids in the conduction of electrical activity in and between cells.
