🧠 - As a male with a brain that took a long time to fully mature, this incredibly interesting topic has always been close to my heart Fantastic post from @neuroradiology Male/female differences exist in every major part of the Human brain. Through molecular, animal, and neuroimaging studies, a great deal of information regarding the differences between male and female brains and how much they differ in regards to both structure and function has been uncovered. This may be due to the fact that females have a more intricate evaluation of risk-scenario contemplation, based on a prefrontal cortical control of the amygdala. For example, the ability to recall information better than males most likely originated from sexual selective pressures on females during competition with other females in mate selection. Recognition of social cues was an advantageous characteristic because it ultimately maximized offspring and was therefore selected for during evolution. Oxytocin is a hormone that induces contraction of the uterus and lactation in mammals and is also a characteristic hormone of nursing mothers. Studies have found that oxytocin improves spatial memory. Through activation of the MAP kinase pathway, oxytocin plays a role in the enhancement of long-term synaptic plasticity, which is a change in strength between two neurons over a synapse that lasts for minutes or longer, and long-term memory. This hormone may have helped mothers remember the location of distant food sources so they could better nurture their offspring. Meta-analysis of grey matter in the brain found sexually dimorphic areas of the brain in both volume and density. When synthesized, these differences show volume increases for males tend to be on the left side of systems, while females generally see greater volume in the right hemisphere. Cahill L (June 2006).
