Neuronal Representation of Sound Intensity: A Statistical Evaluation
Original language description
In the mammalian brain, intensity of an acoustic stimulus is represented predominantly by the neuronal discharge rate { the number of action potentials (spikes) per second. Due to inherent randomness of neuronal firing, however, the spike counts for a repeated stimulus vary. The precise assessment of stimulus intensity thus depends on the statistic properties of discharge patterns, particularly on the mean and variance of the spike counts. Employing the signal detection theory and theory of random pointprocesses, the current work statistically evaluates the theoretical models of random activity as well as the published neuronal data recorded in the auditory nerve of domestic cat and compares the results with psychophysical experimental findings. Conclusions are drawn relating to the problem of precise intensity coding, as well as to the design of future experiments.
