Verified
The summing up of excitatory and inhibitory signals in a neuron is called
A) repolarization.
B) inhibition.
C) synapse.
D) synaptic integration.
E) sympathetic response.
Synaptic Integration
The process by which multiple synaptic potentials combine within a single neuron, critically influencing the neuron's output.
Synapse
The junction between neurons through which nerve impulses pass, facilitated by the release and reception of neurotransmitters.
Excitatory
Pertaining to or causing excitation, often used in the context of neuronal activity where excitatory signals lead to the activation or stimulation of a nerve cell.

Final Answer :
D
Explanation :
The summing up of excitatory and inhibitory signals in a neuron is called synaptic integration. This process occurs at the synapse, where neurotransmitters bind to receptors on the postsynaptic neuron's dendrites and cell body, resulting in either depolarization (excitatory) or hyperpolarization (inhibitory). Ultimately, the signals are integrated at the axon hillock, where the decision is made whether to fire an action potential or not.
