- Abstract:
- In this paper，a method waspresented to determine the bandof gamma oscillation，and the eharac— teristics of the gamma oscillation response to simple graphics with different topologies wasexplored．First，the method combining wavelets transform and power spectrum wasadoptedto determine the accurategamma band range of the localfield potentials in rat’S primary visual cortex．Secondly，the latencyperiods ofgamma oscillation for simple graphics stimuluswith different topologies were calculated andthe curves of mutual informa．tionbetween the stimulus sequences andpower spectrums in gamma bandwere estimated．The means，maxi．mumvalues and the frequencies at themaximumvalues ofthe curveswereextractedas the feature parameters．Finally，these characteristics were analysed statistically with one—way analysis of variance．The experiment re．suits showthatundervisual stimulations the gamma-bandoscillations exist obviously in the primary visual cot．tex(V1)ofanesthetized rat．The gamma oscillations were significantly selective to the topological features of simple graphic stimulations．
