The Body’s Built-in Ethernet Connection

A fascinating new paper in Current Biology estimates the bandwidth of the eye-brain pathway in humans:

Calculating the proportions of each cell type from receptive field size and coverage factor, we conclude (assuming independence) that the approximately 105 ganglion cells transmit on the order of 875,000 bits/s. Because sluggish cells are equally efficient but more numerous, they account for most of the information. With approximately 106 ganglion cells, the human retina would transmit data at roughly the rate of an Ethernet connection.
