Abstract
Groh. Eye-centered, head-centered, and complex coding of visual and auditory targets in the intraparietal sulcus. J Neurophysiol 94: 2331–2352, 2005. First published April 20, 2005; doi:10.1152/jn.00021.2005. The integration of visual and auditory events is thought to require a joint representation of visual and auditory space in a common reference frame. We investigated the coding of visual and auditory space in the lateral and medial intraparietal areas (LIP, MIP) as a candidate for such a representation. We recorded the activity of 275 neurons in LIP and MIP of two monkeys while they performed saccades to a row of visual and auditory targets from three different eye positions. We found 45 % of these neurons to be modulated by the locations of visual targets, 19 % by auditory targets, and 9 % by both visual and auditory targets. The reference frame for both visual and auditory receptive fields ranged along a continuum between eye- and head-centered reference frames with �10 % of auditory and 33 % of visual neurons having receptive fields that were more
