Question

Assume all of the presynaptic synapses identified produce epsps. If two of these synapses fired simultaneously, which synaptic combination brings the initial segment closest to threshold based on spatial summation? click on the appropriate synapses.

Answer 1

Based on spatial summation, the synapses closest to each other will brings the initial segment closest to threshold.

What are Excitatory Post-Synaptic Potentials, EPSPs?

Excitatory Post-Synaptic Potentials, EPSP, are postsynaptic potential changes that are induced by neurotransmitters which depolarizes the cell, and hence increases the likelihood of initiating a postsynaptic action potential.

Based on spatial arrangement, the summation of two simultaneously fired synapses that is greater than or close to threshold potential will produce an action potential.

Therefore, the synapses closest to each other will brings the initial segment closest to threshold.
