Question

n the process of spacial summation, _______ are added together and ________ are subtracted from that total to determine whether ________ will be created at the trigger zone of the post-synaptic neuron.

Answer 1

Hello. You forgot to enter the answer options. The options are:

"A. EPSPs; IPSPs; action potentials  B. IPSPs; EPSPs; action potentials  C. EPSPs; IPSPs; graded potentials  D. IPSPs; action potentials; EPSPs  E. EPSPs; action potentials; IPSPs"

Answer:

A. EPSPs; IPSPs; action potentials

Explanation:

A neuron has the capacity to receive several types of different stimuli simultaneously. These stimuli can be launched by other neurons or from external sources. Regardless, each stimulus received by the neuron causes a change in potential sites that, if located in nearby regions, can intertwine causing the sum of two amplitudes. The opposite can happen and during the interlacing, one local potential can cancel out the other. This is a process called "spatial sum".

In this process, EPSPs are added and IPSPs are subtracted from this total to determine whether action potentials will be created in the trigger zone of the postsynaptic neuron.
