Many neural and behavioral functions are affected by estrogens, including mood, cognitive function, blood pressure regulation, motor coordination, pain, and opioid sensitivity. Blockage of N- methyl- d -aspartate receptors decreases testosterone levels and enhances postnatal neuronal apoptosis in the preoptic area of male rats.

Discussion The goal of this study was to investigate sexual dimorphism in sensorimotor-based cognitive activity in speech discrimination. Similarly, sex differences in medullary motoneurons that innervate muscles of the larynx in clawed frogs 2or muscles of the dewlap in green anoles 3have been linked to more frequent and intense use of these structures during courtship in males.
III; Quinnett, Paul, eds. Gonadal hormone receptors have also been found in the basal fore-brain nuclei. Neural, not gonadal, origin of brain sex differences in a gynandromorphic finch. Compared with bird song control areas, it has been much more frustrating to determine the function of the sexually dimorphic nucleus of the preoptic area SDN in rats, which is several times larger in males than in females 9.
Third, behavioral 1718 and neuroimaging studies using various techniques 1219 — 25 have revealed sex-based differences in tasks with different attentional demands brain development sex differences in human in Thornton also may apply to speech perception.
Lateralization may differ between the sexes, with men often being said to have a more lateralized brain. De Vries. Intrahippocampal oestrogen brain development sex differences in human in Thornton modulate memory processes [ ]. Culture and Socialization Postnatal social factors are generally presumed to be involved in the development of sexual orientation .
Many of such sex differences described in the human brain arise during development by an interaction of sex hormones and the developing neurons, although direct genetic effects are probably also involved [ ].
Subsequent PI3 kinase activation via ERs stimulated translation of postsynaptic density protein 95 PSD in dendrites to provide a postsynaptic scaffold for spine synapse maturation. Daliri A, Max L. Therefore, the sex difference in Bcl-2 expression may indeed contribute to differentiation of the SDN.
