BRIEF COMMUNICATIONS

Detection and prediction of periodic patterns by the retina pp552 - 554
Greg Schwartz, Rob Harris, David Shrom & Michael J Berry II
A fundamental task of the brain is detecting patterns in the environment
that enable predictions about the future. Here, we show that the salamander
and mouse retinas can recognize a wide class of periodic temporal patterns,
such that a subset of ganglion cells fire strongly and specifically in
response to a violation of the periodicity. This sophisticated retinal
processing may provide a substrate for hierarchical pattern detection in
subsequent circuits.
