Sentences with phrase «recorded brain activity patterns»

Using functional magnetic resonance imaging (fMRI), the researchers recorded brain activity patterns as subjects listened to stories of human distress.

Not exact matches

Running the game while recording people's brain activity with a functional MRI machine revealed that people who made similar giving choices (either to give half or what they had, or half of what their partner thought they had) showed similar brain patterns in the medial prefrontal cortex, a region associated with decision - making.

A set of fMRI recordings of subjects» temporal lobes backed up the team's hypothesis: each time a house or face was consciously processed by an individual, the resulting patterns in brain activity were similar.

By recording neuronal activity in monkeys as they performed tasks that caused saccades, Dr. Christopher Pack has shown that there are waves of activity that cross specific vision processing areas of the brain in defined patterns, and that these patterns are reorganized by saccadic eye movements.

Beyond mapping the precise locations of the brain areas controlling these movements for the first time, Chang and colleagues also recorded and analyzed patterns of neuron activity in those areas.

«It is designed to record patient's specific brain activity and recognize patterns that are associated with seizures,» said Kristen Riley, M.D., associate professor in the Department of Neurosurgery.

In an electroencephalogram (EEG)-- a recording of the brain's electrical activity — the synchronous rhythm of the nerve cells manifests as a periodic pattern.

«Our results show we can detect a specific pattern of activity between neurons in the brain, recording instantaneous exchanges between them as persistent signals that can later be visualized under a microscope,» Gallio said.

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.

To determine which neural recordings corresponded to the «ignored» and «attended» speech, the team reconstructed speech patterns from the brain's electrical activity using a mathematical model.

To compare these patterns to the actual electrical activity in the brains, the researchers inserted electrodes capable of recording the firing patterns of individual neurons.

The results recorded significant brain activity as patterning became multi-layered and more complex.
