AP PSYCHOLOGY

Detailed explanation-1: -If the excitatory effects of the neurotransmitters are greater than the inhibitory influences of the neurotransmitters, the neuron moves closer to its firing threshold; if it reaches the threshold, the action potential and the process of transferring information through the neuron begins.

Detailed explanation-2: -Excitatory neurotransmitters have excitatory effects on the neuron. This means they increase the likelihood that the neuron will fire an action potential. Inhibitory neurotransmitters have inhibitory effects on the neuron. This means they decrease the likelihood that the neuron will fire an action.

Detailed explanation-3: -Glutamate transmission, like most chemical neurotransmission, typically begins with the initiation of an action potential near the soma of the presynaptic cell and axonal propagation of the impulse toward presynaptic terminals.

Detailed explanation-4: -Excitatory. Excitatory neurotransmitters “excite” the neuron and cause it to “fire off the message, ” meaning, the message continues to be passed along to the next cell. Examples of excitatory neurotransmitters include glutamate, epinephrine and norepinephrine.
