“…If the prenatal retina to pulvinar pathways were strong at these prenatal times, they could promote the early maturation of MT and the subsequent maturation of dorsal stream visual areas dependent on MT. Yet, architectonic features of MT develop early in MT of marmosets (Bourne and Rosa, 2006) and MT in galagos has inputs densely labeled with PV within days of birth that fades with maturation (Turner et al., 2020). Because of these uncertainties, more studies on the nature of the retina to pulvinar pathway are needed in different primates, both postnatally and prenatally.…”

“…This finding supported the proposal that an early retina to pulvinar to MT pathway is responsible for the early maturation of area MT. Histologically, MT appears to mature nearly as early as primary visual cortex (Turner et al, 2020;Bourne and Rosa, 2006).…”

Here, we describe the postnatal development of retinal projections in galagos. Galagos are of special interest as they represent the understudied strepsirrhine branch (galagos, pottos, lorises, and lemurs) of the primate radiations. The projections of both eyes were revealed in each galago by injecting red or green cholera toxin subunit B (CTB) tracers into different eyes of galagos ranging from postnatal day 5 to adult. In the dorsal lateral geniculate nucleus, the magnocellular, parvocellular, and koniocellular layers were clearly labeled and identified by having inputs from the ipsilateral or contralateral eye at all ages. In the superficial layers of the superior colliculus, the terminations from the ipsilateral eye were just ventral to those from the contralateral eye at all ages. Other terminations at postnatal day 5 and later were in the pregeniculate nucleus, the accessory optic system, and the pretectum. As in other primates, a small retinal projection terminated in the posterior part of the pulvinar, which is known to project to the temporal visual cortex. This small projection from both eyes was most apparent on day 5 and absent in mature galagos. A similar reduction over postnatal maturation has been reported in marmosets, leading to the speculation that early retinal inputs to the pulvinar are responsible for the activation and early maturation of the middle temporal visual area, MT.

In neurophysiology, achieving precise correlation between physiological responses and anatomic structures is a significant challenge. Therefore, the accuracy of the electrode marking method is crucial. In this study, we describe a tungsten-deposition method, in which tungsten oxide is generated by applying biphasic current pulses to conventional tungsten electrodes. The electrical current used was 40–50 μA, which is similar to that used in electrical microstimulation experiments. The size of the markings ranged from 10 to 100 μm, corresponding to the size of the electrode tip, which is smaller than that of existing marking methods. Despite the small size of the markings, detection is easy as the marking appears in bright red under dark-field observation after Nissl staining. This marking technique resulted in low tissue damage and was maintainedin vivofor at least two years. The feasibility of this method was tested in mouse and macaque brains.
