A neuron that engages in spatial summation acquires a mutation that causes dendrite overgrowth and promiscuous synapsing.What is the likely outcome?
A)abnormally low frequency of action potentials
B)summation will not occur
C)abnormally high frequency of action potentials
D)action potentials with stronger depolarization

Question

Quizplus · Accepted Answer

Dendrite overgrowth and promiscuous synapsing would result in an abnormally high number of inputs to the neuron, leading to an abnormally high frequency of action potentials. This is because the increased number of synapses would increase the amount of spatial summation occurring, resulting in a greater likelihood of reaching the threshold for action potential generation.
