28 Spike train mutual information measurements quantify stimulus specific aspects of neural encoding. Mutual information of bullfrog peripheral auditory neurons was estimated –1.4 bits/sec for broadband noise stimulus –7.8 bits/sec for bullfrog call-like stimulus

29 Summary Information theory quantifies how much a response says about a stimulus –Stimulus, response entropy –Noise entropy –Mutual information, KL divergence Maximizing information transfer yields biological receptive fields –Factorial codes –Equalization –Whitening Spike train mutual information
