10. Glutamate is an example of an excitatory amino acidneurotransmitter that acts via direct synaptic transmission when itis released from presynaptic neurons in the brain.
Which of the following is a mechanism by which an actionpotential is LEAST likely to occur in the associated postsynapticneuron? Summation of ionic events

temporally from rapid stimulation of the presynapticneurons that release glutamate
spatially from the glutamate-releasing neurons and otherneurons releasing an excitatory neurotransmitter that acts via anindirect mechanism
spatially from the glutamate-releasing neurons and otherneurons releasing the excitatory transmitter,aspartate
spatially from the neurons releasing glutamate and otherneurons releasing the inhibitory transmitter, GABA
spatially from many postsynaptic neurons that releaseglutamate.

Answer will be Spatially from neurons releasing glutamate and other neurons releasing the inhibitory transmitter GABA Explanation As we know the glutamate amino acid is an example of excitatory neurotransmitter NT responsible for activation of reaction It always release when gets a excitatory stimulus from the presynaptic terminal and binds with the specific receptor on the post synaptic cells Normally Sodium ions channels are responsible for opening and release Na See Answer
