“…LGN cells are largely monocular ( Casagrande and Boyd, 1996 ), organized in layers based on cell type (magno- parvo-cellular layers with intermixed konio-cells) and eye-of-origin (ipsi- and contralateral). However, there are indications that interocular interactions are possible in LGN ( Dougherty et al, 2021 ; Zeater et al, 2015 ), either due to local interthalamic circuits ( Dougherty et al, 2019 ) or to the large contingent of corticothalamic fibers that feedback into LGN from striate and extrastriate visual areas ( Adusei et al, 2021 ; Briggs and Usrey, 2011 ; Fitzpatrick et al, 2009 ; Hendrickson et al, 1978 ; Lund et al, 1975 ). Whichever their origin, these interocular interactions could account for the oscillations of LGN BOLD responses during binocular rivalry, shown in seminal work by Wunderlich et al, 2005 and Haynes et al, 2005 .…”
