Embarazo: Oxitocina y cortisol

Embarazo: Oxitocina y cortisol

from Dailymotion - most recent videos on October 23, 2009
Duration: 106
El proceso biológico natural del embarazo reduce el estrés en la mujer, al desactivar la hormona cortisol, y aumenta la confianza al liberar oxitocina. Son explicaciones del Informe científico sobre la comunicación materno-filial en el embarazo: células madre y vínculo de apego en el cerebro de la mujer. En la Universidad de Navarra hemos querido divulgar los últimos avances científicos publicados sobre embriología y neurobiología del vínculo afectivo en la gestación. Aunque el embrión resulta extraño a la madre, la atmósfera de tolerancia inmunológica creada en el diálogo molecular hace que la mujer perciba al embrión como algo no propio y, sin embargo, sin señales de peligro que activarían las defensas. Esta tolerancia se inicia a petición del embrión, a través de sustancias que liberan y desactivan todas las células maternas que generarían el natural rechazo hacia lo extraño.Author: raulespert Tags: pregnancy hormones physiology Posted: 23 October 2009 Rating: 0.0 Votes: 0

Coast to Coast AM - 11 Oct 2009 - Natural Highs part 1/12

http://www.youtube.com/view_play_list?p=E90364FAA1DA4BC6 Journalist James Nestor discussed how the brain achieves the feeling of being high in terms of neurology, biology, and physiology through meditations, illusions, common herbs, breathwork offers one of the most potent and beneficial ways to clear the mind and induce relaxation, he noted. Curiously, certain kinds of cheese, such as Stilton, are said to bring about odd and memorable dreams if eaten (around 1 oz.) just before sleep. Specific kinds of audio can induce a variety of mental moods or physiological responses. Binaural Beats, in which a different frequency comes out of the left and right speaker, cause the brain to become confused, and create its own auditory track, he said. And listening to the Theta Wave Brain Sync can lull the mind into a creative and vibrant state, similar to what people experience just before falling asleep. Different visual illusions demonstrate the malleability of the brain, and how perceptions can be altered through imagery. In the 'Vomit Vector,' a series of dots appear to be moving and undulating even though they are completely stationary. He also shared some of his anthropological research, detailing how tribes in Brazil, for instance, ingest bizarre substances such as moth larvae to create altered or psychedelic states.
