Question

Quizplus · Accepted Answer

Programmed cell death, also known as apoptosis, is a natural process in which cells undergo controlled self-destruction. In the brain, apoptosis plays an important role in pruning unnecessary or damaged neurons during development and making room for the formation of new synapses, which allows for neural plasticity and efficient cognitive functioning. Maternal drug or alcohol use during pregnancy can lead to developmental abnormalities and neurological damage but is not directly related to programmed cell death. Additionally, while apoptosis can potentially result in cognitive impairment if it occurs in specific brain regions, it does not necessarily lead to permanent mental retardation.
