Local cortical injections of glutamate and noradrenaline alter high-frequency (245Hz) neuronal activity in rat cortex
Data collected from rat frontal cortical neurons has shown a surprising change in power levels at frequencies surrounding 245Hz following local injections of the neurotransmitters noradrenaline and glutamate. The power spectrum does not change anywhere else up to 1000Hz. This effect does not appear to be related to the firing rate of individual neurons, nor the overall power spectral densities.
