Question

unit 4 - challenge 4.1: the nervous system
which of the following refers to the combination of multiple inputs from neurons synapsing to/with a single neuron?
a.) temporal summation
b.) excitatory postsynaptic potential (epsp)
c.) inhibitory postsynaptic potential (ipsp)
d.) spatial summation

Explanation:

• Temporal Summation: Involves repeated signals from a single neuron over time.
• Excitatory Postsynaptic Potential (EPSP): A depolarization making a neuron more likely to fire.
• Inhibitory Postsynaptic Potential (IPSP): A hyperpolarization making a neuron less likely to fire.
• Spatial Summation: Combines inputs from multiple neurons synapsing with a single neuron.

Answer:

d. Spatial Summation
