Impulse processing

Question 1

Where are neural polls and what are there function

Answer 1

Neurons form pools in the CNS

Each pool receives impulses, processes them and conducts impulses away

Question 2

What is facilitation?

Answer 2

Each neuron in a pool may receive excitatory and inhibitory stimuli
A neuron is facilitated when repeated impulse conduction increases its release of neurotransmitters in response to a single impulse

Question 3

What is convergence?

Answer 3

Impulses from two or more incoming axons may converge on a single neuron
Convergence enables impulses from different sources to have an addictive effect on a neuron

Question 4

What is divergence

Answer 4

Impulses occurring on a neuron of a neuron pool often synapse with several other neurons

Question 5

What is a result of a divergence?

Answer 5

The action of a single neuron may be amplified to affect more postsynaptic cells
