Serotonin in the raphe nuclei: regulation by light and an endogenous pacemaker.

abstract：:Human cognitive decisions can be strongly susceptible to the manner in which options are presented ('framing effect'). Here we investigated the neural basis of response adjustments induced by changing frames during intuitive decisions. Evidence exists that the anterior cingulate cortex plays a general role in behavior...
