Xochitecatl [ʃot͡ʃiˈtekat͡ɬ] is a pre-Columbian archaeological site located in the Mexican State of Tlaxcala, 18 km southwest of Tlaxcala city. [1] The major architecture dates to the Middle Preclassic Period (1000–400 BC) but occupation continued, with one major interruption, until the Late Classic , when the site was abandoned.
Involved in orgasm, trust between people, [2] and circadian homeostasis (body temperature, activity level, wakefulness). [3] 50 Pancreatic polypeptide: Peptide: Pancreas: PP cells: pancreatic polypeptide receptor 1: Self-regulation of pancreatic secretions (endocrine and exocrine). It also affects hepatic glycogen levels and gastrointestinal ...
The first biochemical pathology test for any brain disease can be attributed to Vito Maria Buscaino (1887-1978), a neuropsychiatrist who studied schizophrenia. He found that treating her patients' urine who had schizophrenia, extrapyramidal disorders, or amentia, with 5% silver nitrate produced a black precipitate linked with an abnormal level ...
Brain Electrical Oscillation Signature Profiling (BEOSP or BEOS) is an EEG technique by which a suspect's participation in a crime is detected by eliciting electrophysiological impulses. [ 1 ] [ 2 ] It is a non-invasive, scientific technique with a degree of sensitivity and a neuro-psychological method of interrogation which is also referred to ...
Richard Caton discovered electrical activity in the cerebral hemispheres of rabbits and monkeys and presented his findings in 1875. [4] Adolf Beck published in 1890 his observations of spontaneous electrical activity of the brain of rabbits and dogs that included rhythmic oscillations altered by light, detected with electrodes directly placed on the surface of the brain.

The dopamine reward circuitry in the human brain involves two projection systems from the ventral midbrain to the nucleus accumbens-olfactory tubercle complex. First, the posteromedial VTA and central linear raphe cells selectively project to the ventromedial striatum , which includes the medial olfactory tubercle and the medial NAC shell .
The brain's magnetic field, measuring at 10 femto tesla (fT) for cortical activity and 10 3 fT for the human alpha rhythm, is considerably smaller than the ambient magnetic noise in an urban environment, which is on the order of 10 8 fT or 0.1 μT. The essential problem of biomagnetism is, thus, the weakness of the signal relative to the ...
MAO-A appears at roughly 80% of adulthood levels at birth, increasing very slightly after the first 4 years of life, while MAO-B is almost non-detectable in the infant brain. Regional distribution of the monoamine oxidases is characterized by extremely high levels of both MAOs in the hypothalamus and hippocampal uncus, as well as a large amount ...
