Sentences with phrase «form synaptic connections»

Feng studies proteins that form the synaptic connections between neurons, and his original goal was simply to see whether defects in such proteins could cause abnormal behavior.

Not exact matches

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.

After all, each brain is unique, and each brain keeps changing in response to new experiences, forming new synaptic connections between neurons and even — contrary to received wisdom a decade ago — growing new neurons.

«Up - regulating MHCI is essential for the maternal immune response, but changing MHCI activity in the fetal brain when synaptic connections are being formed could potentially affect synapse density,» Boulanger said.

A form of learning in the marine mollusk Aplysia, long - term sensitization of the gill - and siphon - withdrawal reflex, results in the formation of new synaptic connections between the presynaptic siphon sensory neurons and their target cells.

Long - term memories likely form when selective alterations in synaptic connections occur within patterns of neurons called neuronal ensembles.

Building on their previous work that identified and activated memory cells, a group led by RIKEN Brain Science Institute and RIKEN - MIT Center Director Susumu Tonegawa has now shown that spines — small knobs on brain - cell dendrites through which synaptic connections are formed — are essential for memory retrieval in these AD mice.

Projection neurons form connections with memory neurons at synaptic junctions that resemble small bulbs strung along the wire - like axons.

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.

A microscope image shows the location in the brain of a mouse where nerve cells from the ear enter the brain and form cup - like synaptic connections with brain cells.

Studies show that nitric oxide signaling and the blood flow increases it stimulates play a central role in nerve cell maintenance, growth and repair.,, Most pertinent to anyone looking to enhance their aptitude for learning, nitric oxide - induced blood flow also makes forming new memories physically possible as it plays a key role in what neurologists call long - term potentiation, a process required for assembling and reinforcing new synaptic connections throughout the entire cerebral cortex, striatum, and hippocampus.

Most pertinent to anyone looking to enhance their aptitude for learning, nitric oxide - induced blood flow also makes forming new memories physically possible as it plays a key role in what neurologists call long - term potentiation, a process required for assembling and reinforcing new synaptic connections throughout the entire cerebral cortex, striatum

This is called synaptic plasticity and means the brain continues to form new neural connections throughout life.

Hanson and Graham also agree that resiliency is something we can foster at any age because of neuroplasticity (the ability of the brain to form and reorganize its synaptic connections in response to learning or experience).
