Question

Which of the following statements best reflects the nature of synaptic plasticity?

(a) New synapses are created due to the postnatal generation of neurons.
(b) Synaptic response changes in magnitude depending on frequency of stimulation.
(c) There is a change in the type of neurotransmitter used at the synapse.
(d) Neuronal connections are pruned during normal development.

Answer 1

Synaptic plasticity refers to the ability of synapses to change and adapt, allowing for the strengthening or weakening of synaptic connections. It is crucial for processes like learning and memory. One aspect of synaptic plasticity is that synaptic response can change in magnitude depending on the frequency of stimulation.

Step-by-step explanation:

Synaptic plasticity refers to the ability of synapses to change and adapt, allowing for the strengthening or weakening of the synaptic connections between neurons. It is a fundamental process in the functioning of the nervous system, particularly in processes like learning and memory. One important aspect of synaptic plasticity is that the synaptic response can change in magnitude depending on the frequency of stimulation. This means that repeated, high-frequency stimulation leads to the strengthening of synaptic connections, a phenomenon known as long-term potentiation (LTP). On the other hand, low-frequency stimulation can weaken synaptic connections, resulting in long-term depression (LTD).
