We explain what a neuron looks like, what it does, and how it works. Health Conditions ... the neuron is triggered to send an impulse along its axon — this is called an action potential.

Neuron Function Synapses Neural synapses are junctions between neurons that permit neural communication. Synapses come in two different forms: chemical and electrical. 2 Chemical synapses communicate ...

An action potential is a shift in the neuron’s potential electric energy caused by the flow of charged particles in and out of the membrane of the neuron. When an action potential is generated ...

Variability in these properties reflects diversity in pyramidal-neuron function. Action potentials in pyramidal neurons are typically followed by an ADP 87,88,89, which is mediated by voltage ...

To investigate the effects of 2′-hydroxy-4′-methoxyacetophenone (paeonol) on the electrophysiological behavior of a central neuron (right parietal 4; RP4) of the giant African snail (Achatina ...

Excitatory neurotransmitters increase the likelihood that a neuron will fire a signal called an action potential in the receiving neuron. There are several types of excitatory neurotransmitters ...

A new study published in Science has found that neurons in the brain do not follow a single strategy when learning. Instead, different parts of the same neuron—its upper and lower branches—adjust ...

When a neuron activates, an action potential is generated. First, an electrical or chemical input stimulates a dendritic branch on the neuron. If the stimulus is strong enough, ...

Then, when the neuron reaches a threshold, it fires off a long series of signals, or action potentials, even in the absence of stimuli. The researchers call this persistent firing, and it all ...

This news release is available in Japanese. Synapse, the name for the signal-receiving site on a neuron, comes from the Greek word for contact. Neuroscientists used to maintain that neurons form ...
