The standard graduate application process has a sequencing problem. You apply, pay the fee, and hope a lab has space. The Vector Graduate Student Program flips this to put research fit first. 🧵

A first for me: a paper I didn't write was published in a supposedly peer-reviewed journal I've never heard of with me as the sole named author. It's a bibliometric analysis of a field that I have done some work in, so there's a plausible connection, but that's not me.

An intrinsic hierarchical, retinotopic organization of visual pulvinar connectivity in the human neonate
Despite the immaturity of the visual cortex, infants exhibit remarkable perceptual abilities. The pulvinar is hypothesized to support perceptual abilities in infancy and even scaffold the initial development of cortical visual areas. Here, Ayzenberg et al. examined the organization and maturity of connections between the pulvinar and the visual cortex.
