Sentences with phrase «single brain regions»

This method can interrupt the activity of single brain regions for a short period of time and can therefore measure the brain's reaction to this impairment.

In an interconnected network of billions of neurons, it is unlikely that any single brain region is responsible for an experience — even if media coverage touting the «love center of the brain» suggests otherwise.

Scientists know that our memories are stored in specific areas of the brain, but there has been some debate over whether a single brain region can store different memories that control opposing behavior.

Human cognition does not emerge from a single brain region but depends on a team effort involving multiple brain networks.

It is apparent that no single brain region is dedicated to managing multiple languages.

Recent advances allow neuroscientists to study levels of neurotransmitters or their receptors in specific brain regions via PET (positron emission tomography), SPECT (single photon emission computerized tomography), and MRS (magnetic resonance spectroscopy).

Much of the research so far has targeted single regions of the brain, yet it is possible that multiple regions are involved.

The researchers recorded the firing of single neurons in a brain region that controls eye movements.

In a famous set of experiments in human subjects in 2005, neuroscientist Rodrigo Quian Quiroga found that pictures of actor Jennifer Aniston activated a single brain cell in the hippocampus region — the so - called Jennifer Aniston neuron.

At a symposium at The American Society of Human Genetics here last month, they reported zooming in on the genes expressed in a single brain cell, as well as panning out to understand how genes foster connections among far - flung brain regions.

Scientists have long accepted that our ability to abruptly stop or modify a planned behavior is controlled via a single region within the brain's prefrontal cortex, an area involved in planning and other higher mental functions.

MouseLight has already revealed new information, including the surprisingly extensive number of brain regions that a single axon can reach.

Right now the favorite single theater for many people is the prefrontal cortex, a region of the brain located up front, behind one's forehead.

For the analyses, Thompson and his colleagues looked for single - letter (nucleotide base) changes in DNA that correspond to the sizes of key brain regions.

Certain regions of the brain take input from two or more senses and then combine them in a single sensory channel to sharpen the information overall.

At the cellular level, although they share canonical types of inhibitory interneurons (INs) and excitatory principal neurons (PNs), it remains largely unknown to what extent a single type in different brain regions displays similarity in gene expression, axonal shape, connectivity, and developmental origins.

The Times later published a letter signed by 45 neuroscientists explaining that «there is rarely a one - to - one mapping between any brain region and a single mental state.»

In their new Science paper, the researchers analyzed gene expression in single cells across key developmental time points and from different regions of the brain.

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.

The goal of this work is to characterize the role of dendrites in learning and memory processes so as to formulate a unifying theory regarding their contribution in memory formation across brain regions and abstraction levels.This will be achieved via the development of computational models that start at the single cell level and expand to the microcircuit and the network level, while varying in their degree of biophysical detail.

Towards this goal, we build abstract mathematical as well as detailed biophysical models of neural cells and circuits across multiple brain regions (hippocampus, amygdala, PFC) and abstraction levels (single neurons, microcircuits, neuronal networks).

Selected antibodies are applied to test - sections containing brain regions or cell types with known expression based on in situ hybridization (Allen Brain Atlas) and single cell RNAseq data (Linnarsson Lab and Barres brain regions or cell types with known expression based on in situ hybridization (Allen Brain Atlas) and single cell RNAseq data (Linnarsson Lab and Barres Brain Atlas) and single cell RNAseq data (Linnarsson Lab and Barres Lab).

Such complexity is reflected by the involvement of various brain regions and multiple pathways in the etiology of neurodegenerative diseases that render single drug target approaches ineffective.

But, rather than studying the entire nervous system of a single model organism, Professor Graybiel has studied one brain region — a portion of the basal ganglia known as the striatum — in mice, rats, cats, monkeys, and humans using a whole range of technologies from microscopy through electrophysiological recordings to genetics.

His studies suggest that alternate - day fasting, with a single meal of about 600 calories on the fast day, can boost the production of a protein called brain - derived neurotrophic factor by 50 to 400 percent, depending on the brain region.

«Music is represented in mechanisms widely distributed throughout the brain rather than localized in a single region as are other kinds of information, such as visual or movement information,» Parsons reported.
