The three-banded panther worm is rewriting the story of brain evolution

The animal has a brain structure all its own, according to a 2026 preprint. The finding hints that brains could have evolved centralization before regionalization.

Remembering Barbara Finlay, ‘maverick’ of evolutionary neuroscience

Finlay, who died on 12 September, championed the idea that developmental constraints dictate how evolution sculpts brains, a concept she used to model the timing of hundreds of events and align them across mammalian species.

Crows have brains ‘in the fast lane’

The birds accurately complete decision-making tasks twice as fast as primates, although their endbrains look considerably different.

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.

Purkinje cells evolved to have increasingly complex architecture

An increasing proportion of the cerebellar neurons acquired multiple primary dendrites in humans and other apes, according to a comparison of 11 primate species.

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.

What ‘Brain Flows’ gets right

Michael W. Cole’s new book makes a convincing case that the dynamic movement of signals underpins just about everything the brain does, though it misses mention of relevant theoretical and single-cell work.
