Spatial Summation

The summing of several postsynaptic potentials resulting when several presynaptic neurons release neurotransmitter simultaneously. Compare with temporal summation.

Presynaptic Neurons

Neurons that send signals to a synaptic gap, initiating neurotransmitter release for neuron-to-neuron communication.

Neurotransmitters

Chemical substances released by neurons to transmit signals across a synapse to another neuron, muscle cell, or gland cell.

Neuronal Axon

A Neuronal Axon is a long, slender projection of a nerve cell, or neuron, that conducts electrical impulses away from the neuron's cell body.
