Multineuron response to wind stimuli in the American cockroach

摘要

This work describes an experimental system aimed at addressing the problem of how multiple cells code features of sensory information. These experiments on the escape response of the American cockroach, Priplaneta americana, enable a quantitative approach to the problem of collective coding due to good control of the stimulus and simultaneous recordings from a large fraction of the coding cells. The following results are presented: (a) some cells code for features of the wind that are not simple directional in nature, (b) compound events, defined as simultaneous firing of two cells, represent features of the stimulus that are different than each of the individual cells.
