Thinking on your feet: potentially enhancing phylogenetic tree learning accessibility through a kinaesthetic approach - Evolution: Education and Outreach Background Phylogenetics is one of the main methodologies to understand cross-cutting principles of evolution, such as common ancestry and speciation. Phylogenetic trees, however, are reportedly chall...

Because many of the biggest open questions in neuroscience still revolve around the cerebral cortex โ€” how it emerged, expanded, diversified, and why it differs so much across species.

We now describe the cortex in extraordinary detail:
cell types, layers, gene expression, developmental programs.
Yet description alone doesnโ€™t explain why the cortex is built the way it is โ€” or why evolution took such different paths in different lineages.

Importantly, cortical evolution is not just about the past.
Many vulnerabilities of the human brain, from developmental disorders to psychiatric disease, may be inseparable from the evolutionary trajectories that shaped cortical expansion and complexity.

Only by comparing species can we distinguish what is conserved from what is derived, what is fundamental from what is contingent, and which features come with hidden costs.

From genes to dynamics: Examining brain cell types in action may reveal the logic of brain function Defining brain cell types is no longer a matter of classification alone, but of embedding their genetic identities within the dynamical organization of population activity.

Defining brain cell types is no longer a matter of classification alone, but of embedding their genetic identities within the dynamical organization of population activity, writes @lmprida.bsky.social.

CORTICAL EVOLUTION CONFERENCE 
June 15-17, 2026
Organizers: Verรณnica Martรญnez Cerdeรฑo, Fernando Garcรญa Moreno, Elena Vecino, and Stephen Noctor.
https://ventricular.org/corticalevolution26/
Topic: The Cortical Evolution symposium will promote the dissemination of novel ideas and concepts to shed light on evolution of the mammalian cerebral cortex. The goal of this conference is to further our understanding of factors involved in cortical evolution that are relevant for human brain function under normal and pathological conditions. Experts from prestigious research universities in the Americas, Europe, and Africa will present their most recent findings at the meeting. 150 faculty, students, and interested parties are expected. Attendees will have the opportunity to present their work in poster format, and six abstract submissions will be selected for a short oral presentation. The meeting will be organized into topical 5 sessions:

Cortical Development
Cortical Evolution
Evolution of Cellular Types
Evolution of Cortex and Behavior
Paleoanthropology

"High-resolution activity maps of PFC did NOT align with cytoarchitecturally defined subregions."
Key tenet in neuroscience is that cytoarchitectonic boundaries correspond to functional ones.

Rock art from at least 67,800 years ago in Sulawesi - Nature A hand stencil painted on a cave wall on a small island off the coast of Sulawesi more than 67,800โ€‰years ago suggests a very early occupation of Wallacea.

The oldest documented rock art in the world.

I am also thinking of the industry interest in these numbers, and developers who make money off them are not contributing to acquiring new data.

I am so skeptical of any lucky numbers, unfortunately! Instead let's show WHY we need more comparative brain data!
