- Abstract:
- In order to recognize the orientation encoding mechanism in the primary visual cortex ( V1 ), a hy.brid encoding method integrating firing rates and the inter-spike-intervals of neurons in rats’primary visualcortex was proposed based on Bayesian estimation theory here. The gratings with different orientations wereused to stimulate the anesthetic lE rats, and their spike sequences were collected by the microelectrode array ,the firing rates and inter-spike-intervals were integrated to encode the orientation using Bayesian estimationtheory, And the results were compared with the encoding ones with firing rates simply. The results showed thatthe encoding precision of the hybrid method was higher than the precision of the firing rate method. It is alsoproved that inter-spike-intervals and the firing rates in rats’area V1 encode the orientation together.
