Final answer:
The cell body of a neuron, also known as the soma, is the integrator part that determines if there's enough information to create an action potential. It receives signals from dendrites and integrates them before passing the signal to the axon. When sufficient stimulation is received, the neuron generates an action potential.
Step-by-step explanation:
The integrator part of a neuron that determines if there's enough information to create an action potential is the cell body. When a neuron is sufficiently stimulated, it generates an action potential that propagates down the axon towards the synapse. If enough neurotransmitters are released at the synapse to stimulate the next neuron or target, a response is generated.
