Multiple Choice

What can happen to a neurotransmitter after it is released into the synaptic gap?

Multiple Choice

Which of the following is a function of excitatory neurotransmitters?

• They turn on neurons and excite them to send messages to other neurons.

• They turn off neurons and prevent excitement.

• They slow down communication between neurons.

• They only regulate hormonal processes.
