Sentences with phrase «synaptic strengthening»

MIT neuroscientists, led by Richard Cho, explain the mechanisms for synaptic strengthening in a 2015 article, also published in Neuron.

By observing these natural stimuli, professor Holtmaat's team was able to demonstrate that sensory stimulus alone can generate long - term synaptic strengthening without the neuron discharging either an induced or natural electrical pulse.

Learning and memory are governed by a mechanism of sustainable synaptic strengthening.

A potential bridge is a process called long - term potentiation (LTP), a type of synaptic strengthening that has been scrutinized in slices of rodent hippocampus and is widely considered a likely physiological basis for memory.

Not exact matches

When new information needs processing, the nerve cells can develop new synaptic contacts with their neighbouring cells or strengthen existing synapses.

The tiny electrical currents tDCS uses — generally one to two milliamps — can not actually trigger the chemical impulse that crosses a synapse, but some researchers believe tDCS strengthens synaptic connections to make learning more efficient.

In a developing fetus, she surmised, those phone calls would reach groups of nerve cells in the LGN; as their synaptic connections with the retinal neurons strengthened, the LGN neurons would begin forming «area codes» of their own.

It occurs when one neuron fires closely after another, which strengthens their synaptic connection and makes it slightly more likely the first will trigger the second in the future.

For instance, every time we learn something, the new information is transformed into memory through synaptic plasticity, a process in which synapses are strengthened and become more responsive to different stimuli or environmental cues.

It manifests itself in two forms: as long - term potentiation, LTP, a strengthening of synaptic efficacy, and as long - term depression, LTD, a weakening of synaptic efficacy.

«The appropriate balance of synapses strengthening and weakening, collectively termed synaptic plasticity, is critical for appropriate brain function.

As professor Holtmaat explains: «It is possible that sensory stimulation, when combined with another activity (motor activity, for example), works better for strengthening synaptic connections.»

What develops the brain is stimulation — the process of synaptic architecture depends on stimuli — it strengthens the connections needed and prunes those not needed.

NMDA receptors are known to be involved in weakening or strengthening synapses in neural connections, changes that are called synaptic plasticity, and in memory formation.

Previous work had shown that spines grow when neurons undergo long - term potentiation, a persistent strengthening of synaptic connectivity that happens naturally in the brain but can also be artificially induced through stimulation.

The findings offer support for Tonegawa's new hypothesis that the strengthening of synaptic connections, while necessary for a memory to be initially encoded, is not necessary for its subsequent long - term storage.

When the researchers modeled the effects in mice, they found it strengthened the connections between neurons that make learning possible — what is known as synaptic plasticity — by increasing the action of a cell receptor critical to forming memories.

This strengthened the synaptic connections without overstimulating them — thus translating learning into long - term memories.

Learning and memory have been closely linked to strengthening of synaptic connections between neurons (i.e., synaptic plasticity) within the dentate gyrus (DG)- CA3 - CA1 trisynaptic circuit of the

That process, in turn, may generate «synaptic plasticity» allowing the junctions between nerve cells to strengthen and weaken more easily.

On top of a healthy diet and regular exercise, mental stimulation is what it takes to strengthen synaptic networks.

Scientists have long known that the adult brain is surprisingly plastic — we can strengthen synaptic connections through repetition, for example, to improve our memory.

When neurons are frequently fired, synaptic connections are strengthened; the opposite is true for neurons that are rarely fired.
