In synaptic connections, two afferent volleys from adjacent areas within a short time induce a greater response from a postsynaptic cell than either separately.
Summation of postsynaptic responses in a postsynaptic cell from two or more synaptic inputs that are active at about the same time.
In the production or inhibition of action potentials in a postsynaptic neuron, the interaction of depolarizations and hyperpolarizations produced by several terminal boutons.
is performed in the postsynaptic cell and refers to the integration of all synaptic inputs at a given point in time at the trigger zone
In a neuron, summation of two or more inputs of the same type from different locations that occur at about the same time
The process whereby two or more stimuli that are individually below threshold will elicit a reflex if they occur simultaneously at different points on the body.
integration by a postsynaptic neuron of simultaneous synaptic currents that arise from the terminals of different presynaptic neurons
Spatial summation is a way of achieving action potential in a neuron which involves input from multiple cells. Spatial summation is the algebraic summation of potentials from different areas of input, usually on the dendrites. Summation of excitatory postsynaptic potentials allows the potential to reach the threshold to generate an action potential, whereas inhibitory postsynaptic potentials can prevent the cell from achieving action potential.
