“The cerebral cortex is responsible for voluntary movements, perception of sensory input and of highly complex functions such as memory, learning, reasoning and language,” said Gabrielle de Courten-Myers, MD, study author and associate professor of neuropathology at the University of Cincinnati. “Males possess more tightly packed and more numerous nerve cells (neurons) than females. Neurons send and receive electrical signals that influence many functions of the body and create thoughts and feelings. Females tend to have more neuropil, the fibular tissue that fills the space between nerve cell bodies and contains mainly nerve cell processes (synapses, dendrites and axons) that enable neurons to communicate with numerous other nerve cells.”
This research may explain previous findings that women are more prone to dementing illnesses than are men. Although a man and woman may lose the same number of neurons due to a disease, such as dementia, the womans functional loss may be greater because the cells lost are more densely connected with other neurons. Added de Courten-Myers, “Conversely, in males, the functional reserve may be greater as a larger number of nerve cells are present, which could prevent some of the functional losses.”
Although these gender-specific variations cause tangible differences in how the brain functions, one type is not “better” or “worse” than the other. Said de Courten-Myers, “It seems reasonable to assume that specific functions may benefit from the presence of more
