Harvard researchers have mapped and cataloged more than 70,000 synaptic connections from about 2,000 rat neurons, using a ...

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.

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 ...

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

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

Researchers have discovered a new type of neuron that plays a fundamental role in recognition memory -- how the brain registers the difference between new and familiar objects and forms long-term ...

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.

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.

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 ...

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