Sex hormones influence the structure and function of the brain, but little is known about the effect of hormone therapies HT on changes in the brain during menopause. A new study shows smaller increases in structural brain changes related to aging were associated with hormone-level changes from transdermal estradiol or oral conjugated equine estrogen. Age-related changes in learning and memory have been associated with changes in the structure of the brain. Visually, such structural changes can be seen through magnetic resonance imaging in what appear as bright white spots in the brain known as white matter hyperintensities. These changes in brain structure and in cognitive function may, in part, be related to the lower estrogen levels resulting from menopause. In a new study involving participants from the Kronos Early Estrogen Prevention Study, researchers investigated the link between the changes in hormone levels from both the brain and the ovary with different HT formulations and structural changes in the brain associated with aging compared with placebo.

Background: While sex hormones and their receptors play well-known roles in progression of primary tumors through direct action on sex steroid hormone-responsive cancer cells, emerging evidence suggest that hormones also play important roles in metastatic progression by modulating the tumor microenvironment. Estrogens and androgens synthesized in gonads and within the brain influence memory, behavior, and outcomes of brain pathologies. Yet, their impact on brain metastatic colonization and progression is just beginning to be explored. Recent findings: Estradiol and testosterone cross the blood-brain barrier and are synthesized de novo in astrocytes and other cells within the adult brain.

7 Weird Things That Happen To Your Brain After Sex

After you arrive, explains cognitive neuroscientist Gina Rippon in her riveting new book, The Gendered Brain , the big reveal will be hidden within some novelty item, such as a white iced cake, and will be colour-coded. If it is blue, it is a…. For my part, I was braced for an encounter with an egghead, who would talk at me and over me. Rippon is patient, though there is an urgency in her voice as she explains how vital it is, how life-changing, that we finally unpack — and discard — the sexist stereotypes and binary coding that limit and harm us.

The regions described as amygdala nuclei encompass several structures of the cerebrum with distinct connectional and functional characteristics in humans and other animals. The basolateral complex can be further subdivided into the lateral, the basal, and the accessory basal nuclei. Anatomically, the amygdala, [8] and more particularly its central and medial nuclei, [9] have sometimes been classified as a part of the basal ganglia. In one study, electrical stimulations of the right amygdala induced negative emotions, especially fear and sadness. In contrast, stimulation of the left amygdala was able to induce either pleasant happiness or unpleasant fear, anxiety, sadness emotions.
