Sentences with phrase «through brain circuits»

One goal in neurobiology is to understand how the flow of electrical signals through brain circuits gives rise to perception, action, thought, learning and memories.

Just as computers use programming languages such as Java, the brain seems to have its own operating languages — a bewildering set of codes hidden in the rates and timing with which neurons fire as well as the rhythmic electrical activities that oscillate through brain circuits.

When we hold an item in working memory, these oscillations move through brain circuits in waves that rise and fall scores of times.

Not exact matches

Three times I have been felled by lightning pain as seizures short - circuited my brain; Three times, waking in hospitals at dawn all memory of my poetry was gone, and once I'd nearly bitten through my tongue.

The change in what the volunteers saw was so fast, Dilks says, that it must be due to the brain redirecting signals through pre-existing circuits rather than forging new connections.

Ultimately, these neurons form a circuit between the brain and the target tissue through which chemical and electrical signals are relayed.

The researchers also investigated how pheromone signals are transmitted through the olfactory circuit in the brain.

To map how the same sense can be perceived differently in the brain, the NYU Langone team, led by postdoctoral fellow Kishore Kuchibhotla, PhD, monitored nerve circuit activity in mice when the animals expected, and did not expect, to get a water reward through a straw - like tube (that they see) after the ringing of a familiar musical note.

Rushworth is now mapping the circuit using diffusion - weighted MRI, which tracks the movement of water through the brain, to find out which areas the DPFC is linked to.

«We show that an immune molecule directly controls brain circuits through neurons,» Kipnis says.

«We are exploring this through modelling information processing in parts of the insect brain, and we find that often, exceedingly difficult tasks, for example in visual pattern recognition or floral scent learning, can be solved with extremely simple neural circuits.

Similarly, using light to stimulate atrophied neurons that may be associated with schizophrenia could someday allow clinicians to repair cognitive function, Boyden said, and enhance the flow of information through disordered brain circuits that otherwise may be giving rise to delusions and paranoia.

New research presented by Dr. Jonathan Britt, from McGill University, helps to better understand how reward signals, such as those produced by addictive drugs, travel through the brain and modify brain circuits.

Prior research showed that the mPOA is important for social and reproductive behavior in all vertebrate species studied from fish to human, but it has been unclear whether this area drives social motivation through circuit connections with reward systems in the brain.

Understanding the dynamic mechanisms that lead to the emergence of brain functions through the development and continuous remodelling of neural circuits, and the constraints that disease and aging impose to this multi-modal plasticity has important implications that go beyond fundamental neuroscience, from education policies to brain repair.

Through the activation of brain circuits with light, female voles were tricked into selecting specific partners

The information gathered by your senses is transmitted by nerve cells, or neurons, to specific brain regions where the signal is routed through circuits and sent downstream to areas that essentially translate the information into behavior and get you back on track.

At Weizmann, Dr. Spiegel will be establishing his own independent research group which will attempt to identify the molecular and cellular mechanisms through which experience alters the structure and function of neural circuits in the brain in behaviorally relevant ways and to understand how these processes, when they go awry, might give rise to psychiatric disorders.

Over hundreds of years, scientists have learned much about the brain, including the countless methods through which information is transferred from neuron to neuron at a junction called a synapse, and how hundreds — even thousands — of neurons can function together to form a larger circuit responsible for any given activity.

We know a great deal about the genomic mechanisms through which androgens and estrogens influence behavior; by turning genes on and off and thus affecting levels of proteins in cells, they slowly sculpt the brain circuits and peripheral structures required to produce social output.

DAVIDSON: We know from research that engaging in acts of generosity activates circuits in the brain that we know to be involved in positive emotion, and one of the most powerful ways of activating that circuitry is through prosocial, generous behavior.

We know from research that engaging in acts of generosity activates circuits in the brain that we know to be involved in positive emotion, and one of the most powerful ways of activating that circuitry is through prosocial, generous behavior.

Thus, early adversity and later developmental health are linked through the structural and functional development of specific brain and nervous system circuits, from executive function to responses to stress.
