Question

Quizplus · Accepted Answer

Neurotrophins are life-preserving chemicals that promote the survival, growth, and differentiation of neurons. They are supplied to neurons by their synaptic targets, which release them in response to the activity of the neuron. Neurotrophins also support neural plasticity, the ability of the brain to modify its connections in response to experience. While neurotrophins can be overproduced or underproduced, leading to problems like neuronal death, their primary function is to promote neuron survival. Therefore, options A and B are correct, but C is not.
