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.

When a neuron’s dendrite or cell body receives enough inputs from other neurons via chemical or electrical synapses and a particular threshold for that neuron is exceeded, the neuron is triggered to ...

Between the axon of a transmitting neuron and the dendrite of a receiving neuron is a gap called the synapse —the site at which signals are passed between the brain cells.

Scientists have uncovered a crucial pathway that links brain cell activity to the activation of genes responsible for ...

How does one nerve cell transmit the nerve impulse to another cell? Electron microscopy and other methods show that it does so by means of special extensions that deliver a squirt of transmitter ...

Researchers have identified a unique mitochondrial process in CA2 neurons that supports learning, memory, and social ...

#1 Neurons complete hippocampus loop There's a new, important function for a once-obscure cell population in the brain: CA2 pyramidal neurons, a subset of cells in the hippocampus, form a link between ...

This results in enough neurotransmitter being diffused across the synaptic cleft to trigger the impulse in the postsynaptic neuron. This process is called summation.

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