Extended Data Fig. 5: Retinotopic specificity at three levels of visual processing in the lamprey brain, related to Figs. 1 and 5.
From: The evolutionary origin of visual and somatosensory representation in the vertebrate pallium
Schematic drawings of the lateral pallium, thalamus and optic tectum showing that the retinotopically organised afferents from the retina target specific subgroups of thalamic neurons, which project to both visual pallium and tectum. This highlights the overall maintenance of retinotopic specificity at the three different levels of visual processing in the lamprey brain—visual pallium, thalamus and optic tectum. Hb, habenula; LPal, lateral pallium; ot, optic tract; Th, thalamus.
