Question

A toxin interferes with the opening of the Na+ channels in the postsynaptic membrane, causing them to open more slowly when bound to a neurotransmitter. What would be the effect on the formation of an action potential in the postsynaptic membrane?

Answer 1

All functions performed by the nervous system—from a simple motor reflex to more advanced functions like making a memory or a decision—require neurons to communicate with one another. While humans use words and body language to communicate, neurons use electrical and chemical signals. Just like a person in a committee, one neuron usually receives and synthesizes messages from multiple other neurons before “making the decision” to send the message on to other neurons.
