When the rat's eyes open (P14) the retino-collicular projection is largely mature but the cortico-collicular afferents are naive and mature considerably in the following week. At P14, single units in the superior colliculus' superficial grey layer (SGS) had discrete receptive fields (RFs) (diameter = 15 +/- 1.6 degrees) which expanded with age, reaching 30 +/- 2.6 degrees at P21, possibly reflecting the increasing influence of the visual cortex, whose RFs are known to be enlarged at P21… CONTINUE READING
