Gamma activity correlates to a variety of cognitive processes, including sensory processing, attention, working memory, and action selection ( Bressler et al., 1993 Murthy and Fetz, 1996 Roelfsema et al., 1997 Tallon-Baudry et al., 1999 Fries et al., 2001 Pesaran et al., 2002 Buzsáki, 2006 Beshel et al., 2007 Pesaran et al., 2008). Gamma oscillatory activity (30–100 Hz) is manifested in local field potentials (LFPs) recorded from a wide range of brain areas in both human and animals. Altogether, these results suggest that OFC gamma-band synchronization reflects inhibitory control over a subpopulation of neurons that express information about the emotional valence of actions after a motor decision, which suggests a novel mechanism for response inhibition. Neurons phase-locked to either theta or gamma rhythms but not to both, suggesting that they become associated with separate rhythmic networks involving OFC. In addition to gamma rhythm, OFC field potentials were characterized by theta oscillations during odor sampling. During sampling, this subgroup displayed a suppression in firing rate but a concurrent increment in the consistency of spike timing relative to gamma oscillations. These cells showed action–outcome selective activity, not during stimulus sampling but during subsequent movement responses. However, only a specific subgroup of cells showed consistent phase timing. Spikes of OFC neurons were consistently timed to the gamma rhythm during odor sampling, regardless of the associated outcome. Learning speed was correlated to the slope of the gamma power increment. Gamma power was strongest during the late phase of odor sampling, just before go/no-go movement, and increased with behavioral learning. We conducted multineuron and local field potential recordings in the orbitofrontal cortex (OFC) of rats performing a task in which they made go or no-go decisions based on two olfactory stimuli predicting appetitive or aversive outcomes. However, they have barely been studied in relation to emotional processing and valuation of sensory signals and actions. ReturnThanks to all the coders, see previous posts, for this useful code.Gamma oscillations (30–100 Hz) correlate to a variety of neural functions, including sensory processing, attention, and action selection.

The sequence of the arrays is red, green, blue. The gamma ramp is specified in three arrays of 256 WORD elements each, which contain the mapping between RGB values in the frame buffer and digital-analog-converter (DAC) values. lpRamp : Pointer to a buffer containing the gamma ramp to be set. Lexikos adviced me on this issueīasically i'm trying to use these two API GetDeviceGammaRamp & SetDeviceGammaRamp
