Insulin action impaired by deficiency of the G-protein subunit G ialpha2.

abstract：:We often face alternatives that we are free to choose between. Planning movements to select an alternative involves several areas in frontal and parietal cortex that are anatomically connected into long-range circuits. These areas must coordinate their activity to select a common movement goal, but how neural circuits...
