In the new study, decisions could be predicted based on the pattern of brain activity immediately before a decision was made.

Not exact matches

For example, the intensities and patterns of the brain waves in different areas of the cortex change according to the kind of mental activity that is going on.

Daily weather patterns, brain activity on an EEG (electroencephalogram) and heartbeats on an EKG (electrocardiogram) each generate lines of complex data.

This is the first time a direct connection has been established between a person's eye movements and patterns of brain activity, which follows up on previous studies linking what we see to how we remember.

Vargas - Irwin used an analysis technique he developed, called SSIMS, that can accurately detect patterns of activity in collections of neurons without relying on any assumptions about what the brain is trying to do.

Lamm and his group recently sought the answer to answer this question by combining measures of electrical activity in the brain (via electroencephalogram) with functional magnetic resonance imaging to show blood flow patterns in 25 participants getting rounds of shocks on their hands.

The patterns were surprisingly consistent from person to person, to the extent that the researchers could predict, based on brain activity, the feelings of an individual who had never been scanned before.

«If you look at brain signaling on the level of individual neurons, it looks very mysterious, but if you take a step back and observe the activity of a population of hundreds of neurons instead, you might see simpler, clearer patterns that intuitively make more sense.»

A computer algorithm processed the monkey's brain activity, homing in on patterns of neurons firing as it learned to do the task.

Also, the patterns of brain activity that we see on imaging when they are lying down may not be the patterns that the brain produces during normal upright activity.»

Meaningful progress in cognitive neuroscience depends on mapping patterns of brain activity, which are constantly and rapidly changing with every experience we have.

A scent's location on the map also predicts the brain activity caused by getting a whiff: previous research in a variety of animals such as fruit flies, honeybees, mice, rats and tadpoles showed that neighboring odors cause similar patterns of neuron activity.

Building on the temporal precision of the MEG technique, we show that machine - decoding algorithms capture patterns of neuronal activity that follow the decision and, hence, do not reveal how our brain uses information contained in these patterns.

Answering this question requires classifying neuronal activity patterns recorded from the brain, based on a number of statistical, dynamical and anatomical features and correlating them with observable behaviours, such as the presence or absence of rapid eye movements.

Children with the lowest scores on the social cognition tests showed atypical responses to the unknown words — no response at all, for example, or activity in a different part of the brain, while those with the higher scores showed a more typical pattern of brain activation in the left hemisphere, the authors report online today in PLOS ONE.

These «delayed response tasks» suggest that working memory, at the level of brain cells, is the result of self - sustaining patterns of neural activity — a group of neurons starts firing when the initial information is presented and maintains that firing internally when the stimulus is no longer present until the animal acts on that information.

The findings may even have implications for studying glioblastoma, a common brain cancer whose ability to grow, migrate and hack into the brain's blood supply appears to rely on a pattern of gene activity similar to that now identified in these neural stem cells.

They focused on the so - called N400, a distinct pattern of electrical brain activity that can be measured by electrodes placed on the scalp.

Gaining access to the inner workings of a neuron in the living brain offers a wealth of useful information: its patterns of electrical activity, its shape, even a profile of which genes are turned on at a given moment.

LA JOLLA — Every night while you sleep, electrical waves of brain activity circle around each side of your brain, tracing a pattern that, were it on the surface of your head, might look like the twin hair buns of Star Wars» Princess Leia.

At the same time, another type of brain pattern — alpha activity — is also turned on.

The analysis of functional magnetic resonance imaging (fMRI) data focused on the variations in both local and interregional patterns of brain activity as a function of resistance to peer influence (RPI).
