TRC: Neuronal network

Neuronal network

Neurons communicate with each other by means of electrical or biochemical signals. Neuronal networks are groups of coupled neurons. One neuron receives information from one or more neurons and can transmit the processed information via its synapses towards other neurons. Usually such a neuronal network uses a specific neurotransmitter to transmit the information. Depending on the neurotransmitter, the postsynaptic cell can receive an inhibitory or excitatory signal.

These signals act by slightly increasing or decreasing postsynaptic membrane potential. Therefore bringing it closer or further from the threshold. A neuronal network can have stimulatory or modulatory effects on all kinds of physiological systems in the human body, e.g. memory, release of pituitary hormones and movement.

An example of a neuronal network is shown in the next graphic: dopamine network.

The postsynaptic neuron receives electrical stimuli from the presynaptic neuron.
