Brain scans of both sexes have shown that the pleasure centers of a mans brain show more intense activity than in women during orgasm.Male and female brains demonstrate similar changes during orgasm, with brain activity scans showing a temporary decrease in the metabolic activity of large parts of the cerebral cortex with normal or increased metabolic activity in the limbic areas of the brain.EEG tracings from volunteers during orgasm were first obtained by Mosovich and Tallaferro in 1954. These research workers recorded EEG changes resembling petit mal or the clonic phase of a grand mal seizure. Further studies in this direction were carried out by Sem-Jacobsen (1968), Heath (1972), Cohen et al. (1976), and others. Sarrel et al. reported a similar observation in 1977. These reports continue to be cited. Unlike them, Craber et al. (1985) failed to find any distinctive EEG changes in four men during masturbation and ejaculation; the authors concluded that the case for the existence of EEG changes specifically related to sexual arousal and orgasm remained unproven. So disagreement arises as to whether the experiment conducted by Mosovich & Tallaferro casts a new light on the nature of orgasm. In some recent studies, authors tend to adopt the opposite point of view that there are no remarkable EEG changes during ejaculation in humans. Health
General
Orgasm, and sexual activity as a whole, are physical activities that can require exertion of many major bodily systems.
Neurodevelopmental disorders are a group of disorders that affect the development of the nervous system, leading to abnormal brain function which may affect emotion, learning ability, self-control, and memory. The effects of neurodevelopmental disorders tend to last for a persons lifetime. Types
Neurodevelopmental disorders are impairments of the growth and development of the brain and/or central nervous system. A narrower use of the term refers to a disorder of brain function that affects emotion, learning ability, self-control and memory which unfolds as an individual develops and grows.According to the DSM-5, the neurodevelopmental disorders include the following:
Attention deficit hyperactivity disorder (ADHD)
DLD - Developmental language disorder (formerly known as SLI- Specific Language Impairment)
Communication, speech, or language disorders, expressive language disorder, fluency disorder, social (pragmatic) communication disorder, and speech sound disorder. Autism spectrum disorder (ASD)
Intellectual disabilities (IDs) or intellectual development disorder (IDD, previously called mental retardation) and global developmental delay (GDD)
Motor disorders including developmental coordination disorder, stereotypic movement disorder, and tic disorders (such as Tourettes syndrome), and CAS - Apraxia of speech
Neurogenetic disorders, such as Fragile X syndrome, Down syndrome, Rett syndrome, hypogonadotropic hypogonadal syndromes
Specific learning disorders, like dyslexia or dyscalculia. Traumatic brain injury (including congenital injuries such as those that cause cerebral palsy) and disorders due to neurotoxicants including Minamata disease caused by mercury, behavioral disorders including conduct disorder etc. caused by other heavy metals, such as lead, chromium, platinum etc., hydrocarbons like dioxin, PBDEs and PCBs, medications and illegal drugs, like cocaine, radioactive metals like Po210(which is found in cigarettes), and others.
