Topic: upper visual field

The spatial embedding of the cortical connectome ensures that inter-areal connection strength is largely determined by distance. A flat map of macaque area V1 show that the areal neighborhoods of the far periphery upper and lower visual field representations are highly distinct from each other and from that of the fovea, predicting that they exhibit distinct connectivity profiles. Tracer injections in upper and lower visual fields in areas V1 and V2 revealed different connectivity profiles at different eccentricities. Connection strengths of most projections differ significantly with eccentric
