[Evaluation of the cat brain activation using ECoG on the cat striate cortex].
The striate cortex electrocorticogram has been analyzed in 12 cats in following states: at rest with the eyes closed and with the eyes opened; after light electrical stimulation of ears; somnolence; eye opening after somnolence+; barbituric sleep. The behaviour of cats was controlled and the state of emotional excitability was determined. Spectral and periodometric analysis of ECoG has revealed state-dependent differences of cats in power spectra from 2 frequency ranges (2.8-5.0 Hz and 13.8-20.8 Hz). It is suggested that the ratio of ECoG power spectra in these frequency ranges can be used to evaluate the brain activation of cats.
