Released glutamate traverses this space by passive diffusion, and because its target glutamate receptors in the postsynaptic neuron are ... states of synapses on a cell-assembly basis.

It seems reasonable that some form of cell–cell signaling must be involved ... However, agrin itself is not necessary for the formation of neuron–neuron synapses. This has led to an intensive ...

There are two types of removal: Re-uptake – the neurotransmitter is reabsorbed back into the presynaptic neuron and restored inside a vesicle ready to be used again. For example, noradrenaline.

In one set of experiments, Yaeger activated synapses on the pyramidal neurons and measured the effect on the cells' ...

The brain is an incredibly complex organ, but its billions of neurons have recently been mapped, opening up some fascinating ...

Harvard Medical School neuro-oncologist Annie Hsieh treats patients with gliomas—the most common type of brain cancer, ...

Scientists at Johns Hopkins Medicine, led by Dr. Shigeki Watanabe, have found that axons aren’t the smooth, cylindrical ...

This study provides valuable insights into the differential impact of intrinsic and synaptic conductances on circuit robustness, emphasizing intrinsic plasticity as a crucial but often overlooked ...

The signal travels through the cell body and into the neuron ... the transfer of information. When a neuron receives repeated inputs, its synapse undergoes structural changes that make it ...

The neuron density differences are unique to ... where the brain actually prunes away connections between neuronal cells at the synapse. Too little pruning, means too many connections, which ...

An international team of researchers has discovered a new component of the peripheral nervous system that acts by increasing energy metabolism in the body.
