Abstract
The optical recording system with the computer aided experimental support system has been developed to investigate the animal auditory brain functions. The optical recording system with a 12×12 photodiode array as the image sensors has the spatial resolution about 26μm square and the time resolution about 70μs as the sampled-hold rate. The experimental support software system can afford to analyze the dynamical data using time series analysis in order to make a neural processing model from the observed spatio-temporal data. Some new experimental results on the neural dynamics in the guinea pig auditory cortex have been successfully obtained using this system.
