The Difference on Memory Between Genders

Topics: Hippocampus, Memory, Gender Pages: 5 (1674 words) Published: September 3, 2012
This paper shows five different articles on how either gender can affect the amygdale or affect short term memory; they were all online articles from 1997 to 2010. In Cahill, L (2006, May) his paper uses the term amygdale which is defined as a small section in both the left and right hemisphere of the brain, they are almond-shaped groups of nuclei located deep within the medial temporal lobes of the brain in complex vertebrates, including humans. There are always going to be debates on which gender can suppress more information, men and women have always tried to prove their superiority in the brain related field and there are going to be scientists that argue male’s have a better memory and others that say female’s, but there has been research done to try and determine which one, males or female’s. In the nervous system, the memory related events occur in the hippocampus; it belongs to the limbic system and plays important roles in long-term memory and spatial navigation. The hippocampus is located inside the medial temporal lobe, beneath the cortical surface. It is also one of the first regions of the brain to go when a person develops Alzheimer’s disease. Keywords: amygdale, hippocampus

Gender and Memory
In Cahill L (2006, June) “Research into sex influences is mandatory to fully understand a host of brain disorders with sex differences in their incidence and/or nature. The striking quantity and diversity of sex-related influences on brain function indicate that the still widespread assumption that sex influences are negligible cannot be justified, and probably retards progress in our field”. Cahill has written many articles about neurobiology and neuroscience, and the majority of them were published in 2006. (Cahill L, 2006, May) Shows an example of the “sexually dimorphic function in other amygdale nuclei” comes from a recent study by Braun (et al). A rodent species known as Octodon degus or rat known to central Chile “were exposed to the stress of temporary separation from their mother. They found that hearing the mother’s call during the stress of separation increased the number of serotonin receptors    in the basomedial amygdale of male rodents, but decreased serotonin receptor concentrations in female pups (opposing effects that are reminiscent of those described above for the hippocampus)”. For example, it is significantly larger in men than in women (adjusted for total brain size). Sex differences also exist in its structural relationship with the rest of the brain. In a study of a large sample of men and women, the patterns of covariance in the size of many brain structures were ‘remarkably consistent’ between men and women, with one exception — the amygdale (in particular, the left hemisphere amygdale), which showed several marked sex differences. Several studies now report sex influences on amygdale function, including in the context of its well-known role in memory for emotional events. Extensive evidence from animal research documents that the amygdale can modulate the storage of memory for emotional events, and does so through interactions with endogenous stress hormones released during stressful events”. This amygdale/stress hormone mechanism provides an evolutionarily adaptive way to create memory strength that is, in general, proportional to memory importance. Both lesion and imaging studies have confirmed this conclusion in humans. However, imaging studies have also revealed a sex-related hemispheric lateralization of amygdale function in relation to memory for emotional material. Specifically, the studies consistently indicate a preferential involvement of the left amygdale in memory for emotional material in women, but a preferential involvement of the right amygdale in memory for the same material in men. In an intriguing parallel with the studies in humans, Lalumiere and McGaugh recently reported that stimulation of the right but not the left hemisphere...
