hippocampus is essentially involved in learning and memory processes, and is known to be a target for androgen actions. the high density of the androgen receptors in hippocampus shows that there must be some relationship between androgens and memory. androgen effects on spatial memory are complex and contradictory. some evidence suggests a positive correlation between androgens and spatial memo...

     CA1 region of hippocampus has an important role in learning and memory. Previous reports have shown that androgens like testosterone and its metabolites are present in high concentration in CA1 region of hippocampus. Androgen receptors have also high density in this region. Therefore, it is suggested that neurohormones in CA1 have an important role in learning and memory. It is likely that...

It has been shown that brain glucose metabolism impairment, obesity, and diabetes couldlead to cognitive decline and Alzheimer’s disease (AD) pathogenesis. Kisspeptin (KP) a G-proteincoupled receptor neuropeptide, has been suggested as a link between energy balance andreproduction. Some studies have shown that the attenuation of KP signaling decreases metabolismand energ...
