How does motivation shape learning and memory? In a new review w @ralisonadcock.bsky.social, we propose that under different motivational ‘moods', neuromodulators set distinct neural contexts to determine information processing and memory formation.

Motivation as Neural Context for Adaptive Learning and Memory Formation
Our memories shape our perception of the world and guide adaptive behavior. Rather than a veridical record of experiences, memory is selective. An accumulating body of work suggests that motivational ...

New issue of Nature - with NINE studies on #brain #development from the BRAIN Initiative Cell Atlas Network (BICAN) 🧠🧪🔬

An amazing set of resources for all scientists working on the brain!

🧠 Immersive feature:
www.nature.com/immersive/d4...

🧠 Perspective:
www.nature.com/articles/s41...
Cover of this week's Nature showing a brain rendering Cover caption from the journal: Brain development: Our ability to process information into complex emotions, behaviours and decisions relies on the rich diversity of cell types that make up the human brain. Uncovering the molecular and cellular events that take place during brain development could reveal not only the mechanisms that give rise to this diversity but also shed light on how this process might go awry in neurodevelopmental disorders such as autism and schizophrenia. In this week’s issue, the BRAIN Initiative Cell Atlas Network (BICAN) builds on its previous work creating atlases of cell types in the adult mouse, non-human primate (NHP) and human brains to present cell-type atlases of the developing human, mouse and NHP brains. Across a suite of papers, nine of which are published in Nature, the researchers uncover the complex programs through which cell types emerge during brain development in humans and animals, revealing both the shared and unique features of the human brain. The latest work, along with future research directions, is summed up in a Perspective article by Tomasz Nowakowski and colleagues

Our experience of time is powerfully shaped by boundaries between events (i.e., going from one meeting to the next). But what about time *within an event*? In new work, we find reliable distortions of time based on internal event structure (e.g., beginnings, middles, and ends)! tinyurl.com/n8mn2sn7
