Microscopic analyses suggest that cortical asymmetry might result from different
A) rates of apoptosis.
B) rates of proliferation of progenitor cells.
C) processes of migration.
D) synaptogenesis.

Question

Quizplus · Accepted Answer

Cortical asymmetry is believed to result from differences in the rate of proliferation of progenitor cells during development. This can lead to differences in the number, size, and connectivity of neurons in different regions of the brain, contributing to functional specialization.

Answer choices A, C, and D are not considered primary factors in cortical asymmetry as they do not directly relate to the growth and development of cortical cells. Apoptosis refers to programmed cell death, which can be a normal process in development but is not specific to cortical asymmetry. Migration refers to the movement of cells during development, while synaptogenesis refers to the formation of connections between neurons, both of which can be affected by factors such as gene expression and environmental factors. However, these processes are not thought to be the primary determinants of cortical asymmetry.
