Topic: intrinsic traveling waves

Perceptual sensitivity varies from moment-to-moment with fluctuations in the gain of sensory-evoked responses. We previously found that intrinsic traveling waves (iTWs) of activity in marmoset Area MT regulate the gain of evoked responses for targets presented near perceptual threshold and correlate with the monkey’s detection performance (Davis, Muller, et al. Nature 2020; Davis, Benigno, et al. Nat. Communi. 2021). Here we ask whether target detection also depends on the spiking activity of neurons beyond the retinotopic locus of the target (off-target locations). We hypothesized that activi
