Long-Term Potentiation Within the Brain Has Been Found to Involve

question 197

Multiple Choice

Long-term potentiation within the brain has been found to involve the release of the neurotransmitter glutamate, which stimulates an increase in Ca²⁺ concentration in the postsynaptic cell that causes a cascade of events in that cell, including an increase in the number of glutamate receptors on the postsynaptic membrane. What other change is also observed in the postsynaptic cell?

• A)an increase in ribosomes on the rough endoplasmic reticulum
• B)a decrease in the number of non-glutamate receptors on the synaptic membrane
• C)atrophy of dendrites with no glutamate receptors
• D)an increase in mitotic divisions by the postsynaptic cell
