Unformatted text preview: M ales vs. Females Anna Simpkins Bryan Parker Do men and women have different Do men and women have different brains???? YES Brain Size Brain Size Men brains are typically 11­12% larger than females brains. This is not because they are more intelligent! Men need more neurons to control their greater muscle mass and larger body size! Other Structural Differences Other Structural Differences Continued: Continued: The Cerebral Cortex in the right hemisphere of males tends to be thicker than in females. Women tend to use both sides of the brain when performing spatial and verbal tasks, while men only use one. The Corpus callosum in women tends to be thicker. The brains actually have a difference The brains actually have a difference in gray and white matter?? Women have more gray matter and men have more white matter. White matter is the tissue through which messages pass between different areas of gray matter of the nervous system. Analogy Desktop Computer system White matter continues to develop where gray matter doesn’t. Conclusion? This could explain why women are better at verbal tasks than men, while men are better at spatial tasks. Cognitive Abilities Cognitive Abilities Studies show that men possess greater spatial and mathematical abilities. This may account for why there are more male mathematicians, airplane pilots, architects, and racecar drivers Women, however, have better verbal abilities and a better memory. Emotions Emotions Emotion is associated with the amygdala. A new study has found that amydalas of men and women are polar opposites in terms of connections with the brain. Women have a typically larger deep limbic system which allows women to be more in touch with their feelings and better able to express them.

Monogamy? In prairie voles, OXYTOCIN, VASOPRESSIN, and DOPAMINE have been strongly linked in monogamous pair bonding. Oxytocin and Vasopressin may facilitate attachment to relationship partners by influencing the activity of dopamine in reward circuits during positive interactions with those partners. Human Monogamy Human Monogamy A recent study found that women who reported having a current sexual partner spent less time looking at images of members of the opposite sex. However, MEN spent an equal amount of time looking at images regardless of whether or not they had a current sexual partner. How does the Menstrual Cycle come How does the Menstrual Cycle come into play? Hormones have a dramatic effect on a woman’s thinking ability. The menstrual cycle begins at the brain, at the pituitary gland, more specifically. The pituitary gland discharges hormones which produce progesterone and estrogen. These hormones obviously influence reproduction and ovulation but they can have other affects, as well. Why do you think it is not wise to mess with a girl when it is “that time of the month?” Fun Facts! Fun Facts! In women, neurons on both sides of the brain are activated when listening, while neurons on only ONE side of the brain of men are activated. That explains A LOT!
