Common gene version optimizes thinking -- but with a possible downside
...Daniel Weinberger, M.D. "Normally, enhanced cortex connectivity with the striatum would provide increased flexibil...sted circuit activation, structural and functional connectivity and performance on thinking tasks, likely by increasing gene expression. In 257 affected families, p......ven neighboring neurons of the same type differ in connectivity and function. So, researchers have been trying to figure out the pattern of connections typical of a type of neuron, to see which other cell types they connect with and how those connections are configured. To do this, they need a tracer that can......porns and Honey suggests that this very pattern of connectivity is crucial to generating and shaping brain activity in the resting and active brain. Empirical work on the human brain is challenging due to the fact that the brain's intricacies cannot simply be manipulated and observed. Sporns and Honey compare...
