Skip to Content Skip to navigation. However, this does not seem to fully capture reality. Even when we relish sex, we may be capable of mentalizing, talking, voluntarily postponing orgasm, and much more. This might indicate that the central control mechanisms of sexual activity are quite flexible and susceptible to learning mechanisms, and that cortical brain areas play a critical part. The posterior insula may be particularly important for processing input from the engorged penis and coordinating penile responses.

Sex: How does it impact brain activity?

The largest study to look at sex differences in brain anatomy found that women tend to have thicker cortices, whereas men had higher brain volume. Do the anatomical differences between men and women—sex organs, facial hair, and the like—extend to our brains? The question has been as difficult to answer as it has been controversial. Now, the largest brain-imaging study of its kind indeed finds some sex-specific patterns, but overall more similarities than differences. The work raises new questions about how brain differences between the sexes may influence intelligence and behavior. Most studies have looked at relatively small sample sizes—typically fewer than brains—making large-scale conclusions impossible. In the new study, a team of researchers led by psychologist Stuart Ritchie, a postdoctoral fellow at the University of Edinburgh, turned to data from UK Biobank , an ongoing, long-term biomedical study of people living in the United Kingdom with , enrollees.

Anatomy of the Brain

Arousal is the physiological and psychological state of being awoken or of sense organs stimulated to a point of perception. It involves activation of the ascending reticular activating system ARAS in the brain , which mediates wakefulness, the autonomic nervous system , and the endocrine system , leading to increased heart rate and blood pressure and a condition of sensory alertness, mobility, and readiness to respond. Arousal is mediated by several different neural systems. Wakefulness is regulated by the ARAS, which is composed of projections from five major neurotransmitter systems that originate in the brainstem and form connections extending throughout the cortex ; activity within the ARAS is regulated by neurons that release the neurotransmitters acetylcholine , norepinephrine , dopamine , histamine , and serotonin. Activation of these neurons produces an increase in cortical activity and subsequently alertness.

The frontal lobes are considered our emotional control center and home to our personality. The frontal lobes are involved in motor function, problem solving, spontaneity, memory, language, initiation, judgement, impulse control, and social and sexual behavior. The frontal lobes are extremely vulnerable to injury due to their location at the front of the cranium, proximity to the sphenoid wing and their large size.
