Single-cell recordings in the awake monkey during bistable visual perception have revealed a diversity of roles for individual neurons with regard to an experienced percept. We have recently shown that this perceptual modulation is not only neuron-specific but also stimulus-specific: MT neurons showing perceptual modulation to one stimulus often do not show significant modulation to closely related ambiguous patterns that differ only in the value of a single parameter (Maier et al., SFN 2003). In the present study, we explore how this stimulus-specificity for perceptual modulation might be reflected in the local field potential (LFP) during the perception of ambiguous 3-D rotation, as well as during binocular rivalry flash suppression. Following the presentation of several combinations of rivaling patterns, as well as 3-D rotation, to the same neurons, we analyzed percept-related changes in band-limited power (BLP) during these paradigms. LFP recorded in area MT of two monkeys was band-pass filtered into m...
