How thirteen-lined ground squirrels illuminate retinal development

In most mammalian retinas, rods outnumber cones. But that ratio is flipped in ground squirrels, a quirk that helps Seth Blackshaw explore how retinal cells develop their identities.

Book cover of The Brain, In Theory by Romain Brette.

‘The Brain, In Theory,’ an excerpt

In his new book, Brette pushes back against theories that describe the brain as a “biological computer.” In this excerpt from Chapter 4, he challenges equating brain evolution with programming, and the universality of neural network models.
