Unit 2 – Biological Basis of Behavior
2.4 Neural Firing
mixed difficulty
How could we argue that nerve impulses are predominantly electrical rather than chemical reactions?
Chemicals only play minor roles within synaptic spaces between neurons, not inside them.
Chemical changes occur only after the electrical impulse has reached its destination neuron.
Nerve impulses involve electrically charged particles moving across neuronal membranes to generate an action potential.
Neurons don't rely on chemicals during the refractory period.
