Question
When threshold is reached due to signals arriving at multiple synapses, summation has occurred.
Solution
Yes, that's correct. Summation in neuroscience refers to the process by which individual signals at many different synapses are combined together. It can be either temporal or spatial.
Temporal summation occurs when a single synapse generates signals so quickly that they build on each other.
Spatial summation, on the other hand, occurs when signals from multiple synapses combine to reach the threshold.
So, when the threshold is reached due to signals arriving at multiple synapses, spatial summation has occurred.
