Unbiased Measures of Neuronal Information Transmission and Channel Capacity

Abstract

The response activity of nerve cells in the mammalian visual system was analysed for information bearing properties. Primary findings include: support the multiplex filter hypothesis (nerve fibers encode multidimensional inputs by modulating the amplitudes of a few linearly independent temporal patterns summed to produce an output); the nature of encoding may permit recovery of an image's pattern regardless of its intensity or duration; in higher brain centers, encoded information becomes more evenly distributed among the temporal patterns of a nerve cell; higher brain centers, appear to affect the responses of lower centers through feedback; with sequentially changing visuals inputs, independent responses can occur with images separated by about 30 msec. Keywords: Nerve transmission.
