Intracranial EEG reveals a time- and frequency-specific role for the right inferior frontal gyrus and primary motor cortex in stopping initiated responses.

5 Oct 2009 Inappropriate response tendencies may be stopped via a specific fronto/basal ganglia/primary motor cortical network. We sought to characterize the functional role of two regions in this putative stopping network, the right inferior frontal gyrus ... Read more...


Frontal brain oscillatory coupling among men who vary in salivary testosterone levels.

25 Aug 2009 Recent studies suggest that cross-frequency coupling supports the integration of distinct neuronal oscillatory modes. In particular, spectral coupling between slow-wave delta and fast-wave beta oscillations may reflect subcortical-cortical ... Read more...


Preliminary evidence that both blue and red light can induce alertness at night.

25 Aug 2009 BACKGROUND: A variety of studies have demonstrated that retinal light exposure can increase alertness at night. It is now well accepted that the circadian system is maximally sensitive to short-wavelength (blue) light and is quite insensitive to ... Read more...
