... end result is reduced GABA release and heightened network excitability. In hippocampal slices from seizure-naive rats, tetanic stimulation potentiated DSI in a CB1 receptor-dependent manner. However, tetanization did not potentiate DSI in slices from animals that had experienced in vivo hypothermia-induce...

Complexity constrains evolution of human brain genes

...equences. The higher complexity of the biochemical network in the brain, they suspect, with multiple gene-gene interactions, places strong constraints on the ability of most brain-related genes to change. "We found that genes expressed in the human brain have in fact slowed down in their evolution, contrar...
