... are nerve cells that process information in the brain. Neurons communicate with each other using synaptic connections, analogous to what transistors are in modern computer chips. Synapses store ...
... days and even a lifetime. It is believed that in the area in the brain that stores memories, the synaptic connections between nerve cells that are more active during a specific learning function are ...
... memory loss and cognitive deficits, possibly because insulin receptor signaling in the brain is disrupted, synaptic connections are lost and brain circuits don't work optimally.
In addition, other ...
... that the activity of those neurons has a significant role in behavior. When looking at a change in a synaptic connection between a pair of neurons in the Aplysia nervous system, we know, for some of ...
... connections, or synapses, in response to input from the outside world. It is the refinement of these synaptic connections that is the basis of learning and memory, suggesting that autism at its heart ...
... particular method used to induce forgetting.
If forgetting is induced by random fluctuations in the strength of synaptic connections, then free-lunch learning will be observed. However, the authors ...
... genetically engineered to lack p75. Through their synaptic connections, retinal axons develop a two- ... hope one day to be able to repair these defects and get cells to form functional connections again ...
... in mammals have found that after animals are given drugs such as cocaine or amphetamine, the strength of synaptic connections onto dopamine neurons in VTA is strongly increased, or potentiated. Such ...
... which results in the insertion of AMPA receptors into those synapses and subsequent strengthening of the synaptic connections among hundreds of thousands of neurons. Scientists believe that αCaMKII ...
... formation and tissue development.
"Part of plasticity involves getting receptors to the synaptic connections of nerve cells," Ehlers said. "The movement of neurotransmitter (chemical) receptors ...

In fact, the inappropriate synaptic connections made by cdk5-deficient cells persisted for months after the treatment ...
... memory (i.e. hippocampus) were asymmetrical between synapses receiving input from the left and right hemisphere. Differences were found in the synaptic connections of the learning center of the brain.

By examining specially prepared sections of mouse brain tissue with high ...

If all forms of neurodegenerative disease are propagated along synaptic connections, says Seeley, "the framework would have major mechanistic significance, predicting that the ...
