Shaping brain connections through spontaneous neural activity.
An overwhelming number of observations demonstrate that neural activity and genetic programs interact to specify the composition and organization of neural circuits during all stages of development. Spontaneous neuronal activities have been documented in several developing neural regions in both invertebrates and vertebrates, and their roles are mostly conserved among species. Among these roles...
متن کاملRules for Shaping Neural Connections in the Developing Brain
It is well established that spontaneous activity in the developing mammalian brain plays a fundamental role in setting up the precise connectivity found in mature sensory circuits. Experiments that produce abnormal activity or that systematically alter neural firing patterns during periods of circuit development strongly suggest that the specific patterns and the degree of correlation in firing...

BIG BANG HUMAN BRAIN The universe started with the Big Bang some 13,500 million (billion) years ago. Then very recently, about 200,000 years ago, another " Big Bang " happened – Homo sapiens appeared on earth. It has many genetic similarities with other species such as the chimpanzee and, even more so, with other hominids such as the Neanderthals who lived with us until 30,000 or so years ago. ...
