Conjunctive tuning and cortical geometry shape predictive visual remapping.

ABSTRACT: Perceptual continuity across saccades depends on pre-saccadic remapping of receptive fields (RFs) of visual neurons, a process driven by corollary discharge (CD). Yet how accurate remapping is achieved within the brain's non-uniform representation of visual space remains unclear. We present a recurrent network model in which neurons conjunctively tuned to retinotopic location and planned saccade direction integrate CD signals to remap. Pre-saccadic suppression stabilizes this process by counteracting distortions from direction selectivity. The model preserves cell-cell RF relationships and constrains population dynamics to a low-dimensional manifold. Recordings in macaque V2 during cued saccades validate saccade direction selectivity and preserved RF relationships of visual neurons. The mo
