By contrast, negatively valenced words stimulated greater activation in the right supramarginal gyrus in males, while greater activation in the left part of the hippocampus with negative stimuli. [18] Therefore, different brain regions in males and females could allude to differential responses emotional processing in intimate situations.
The human brain is the central organ of the human nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous ...
Embryonic vertebrate subdivisions of the developing human brain hindbrain or rhombencephalon is a developmental categorization of portions of the central nervous system in vertebrates. It includes the medulla , pons , and cerebellum .
One such region is the nucleus accumbens—a key part of the brain’s reward system that’s fueled by dopamine, a chemical that Wise fondly refers to as “the slutty neurotransmitter” because ...
The limbic system also plays a part in how sexual stimuli are received. [63] A study done about pleasure and brain activity in men showed that electrical stimulation of the limbic system is highly pleasurable, and can sometimes generate orgasmic responses. [63] During genital stimulation different areas of the brain are activated in men and women.
The part of the brain examined is the anterior hypothalamic nucleus (AHdc), a homologue of SDN-POA. Comparison of the AHdc nucleus volumes between Japanese macaque and rhesus macaque (a closely related sister species of Japanese macaque) shows that there is no significant difference between the volume of AHdc in more male-typical macaques and ...
The cerebral cortex is the part of the brain that most strongly distinguishes mammals. In non-mammalian vertebrates, the surface of the cerebrum is lined with a comparatively simple three-layered structure called the pallium. In mammals, the pallium evolves into a complex six-layered structure called neocortex or isocortex. [62]
Human brain in the coronal orientation. Amygdalae are shown in dark red. The amygdala (/ ə ˈ m ɪ ɡ d ə l ə /; pl.: amygdalae / ə ˈ m ɪ ɡ d ə l i,-l aɪ / or amygdalas; also corpus amygdaloideum; Latin from Greek, ἀμυγδαλή, amygdalē, 'almond', 'tonsil' [1]) is a paired nuclear complex present in the cerebral hemispheres of vertebrates.
