Several groups previously reported that (2S,6S;2R,6R)-hydroxynorketamine (HNK) had antidepressant effects in rodents, and that (2R,6R)-HNK increased cortical electroencephalographic gamma power. This exploratory
Under conditions examined to date, ABD exhibits high correlation with the degree of high-gamma (although ABD is more spatially widespread) and the two phenomena can be parsimoniously described as a change in the exponent χ (‘slope’) of the 1/fχ component of the power spectrum57. However...
Both a reduction in the aperiodic (1/ f ) slope and increase in beta/gamma periodic activity contributed to the significant increase in high-frequency power. Increased gamma power, driven by the aperiodic component, was associated with better language ability in the FXS group. No association was...

This deviation from nonlinearity is usually called just gamma and is reported as the exponent of the power law. For instance, “the gamma of this vidicon is 0.43.” The correction of this effect is gamma correction. In the equation above, notice that a gamma value of 1 results in a linea...
In CRTs, screen brightness was proportional to the control grid voltage raised to the 2 to 2.5 power. For this reason, signals had to be encoded with the approximate inverse of this value, and this encoding stuck. As we describe above, in “What is gained by applying a gamma curve?”,...
Vol is the abbreviation of volatility; D.Vol is the abbreviation of downside volatility; CVaR is the cumulative value at risk; PSM is the power spectral measure. MB means moment-based, including both kurtosis and skewness. ER means extreme risks, using simulation data to estimate risks. Naive...
(contrast). Cameras typically do not implement an exact power law, as this would give infinite gain at black: the slope at black is often limited to around 4. In practice, the operator of the cameracontrol unit(CCU; often referred to as the “racks operator”) will adjust the gamma ...

Electrocorticogram (ECoG), obtained from macroelectrodes placed on the cortex, is typically used in drug-resistant epilepsy patients, and is increasingly being used to study cognition in humans. These studies often use power in gamma (30–70 Hz) or hi
