Verified step by step guidance

Begin by understanding the basic function of a neuron, which is to transmit signals. Neurons receive signals from other neurons through synapses.

Recognize that neurons can receive two types of signals: excitatory signals, which increase the likelihood of the neuron firing an action potential, and inhibitory signals, which decrease this likelihood.

Learn that the process of summing up these excitatory and inhibitory signals is crucial for determining whether a neuron will fire an action potential. This process is known as synaptic integration.

Understand that synaptic integration involves two main types of summation: spatial summation and temporal summation. Spatial summation occurs when multiple synapses are activated simultaneously, while temporal summation occurs when a single synapse is activated repeatedly over time.

Conclude that synaptic integration is the correct term for the process of summing excitatory and inhibitory signals, allowing the neuron to make a decision about firing an action potential based on the combined input.
