Spatial learning circuitry fluctuates in step with estrous cycle in mice Jun 25, 2025

Show notes

Cyclic shifts in estradiol levels coincide with changes in dendritic spine density and the activity of place cells in the CA1 region of the hippocampus, a new study shows.

Expanded view of hippocampal function comes into focus Jun 24, 2025

Show notes

After decades of debate, the region's role is being rewritten. Rather than using sensory input to simply log key points in time and space, the hippocampus may serve to contextualize our experiences and memories-and ultimately make predictions about the future.

Many students want to learn to use artificial intelligence responsibly. But their professors are struggling to meet that need. Jun 23, 2025

Show notes

Effectively teaching students how to employ AI in their writing assignments requires clear guidelines-and detailed, case-specific examples.

The big idea with Diego Bohórquez Jun 20, 2025

Show notes

His theories around the neuropod have challenged the boundaries of classic ideas regarding gut-brain communication.

Genetic background steers PTEN syndrome traits Jun 19, 2025

Show notes

People with the syndrome, caused by variants in the gene PTEN, often have autism or cancer, or both, but it depends on the genetic diversity encoded in the components of distinct cell signaling pathways, according to a new study.

Star-responsive neurons steer moths' long-distance migration Jun 18, 2025

Show notes

Cells in the bogong moth brain respond to astral landmarks to orient the insects in the direction they need to go.

This paper changed my life: Bradley Dickerson on how a 1940s fly neuroanatomy paper influences his research to this day Jun 17, 2025

Show notes

This classic paper by zoologist John Pringle describes the haltere-a small structure in flies that plays a crucial role in flight control. It taught me to think about circuits and behavior as greater than the sum of their parts.

Gazing at a location from afar activates place cells in chickadees Jun 13, 2025

Show notes

The results help explain how the hippocampus can recall information about a place without an animal physically revisiting it.

Some dopamine neurons signal default behaviors to reinforce habits Jun 11, 2025

Show notes

Movement-sensing neurons that target the striatum influence a mouse's choice of action by favoring routine.

On the importance of reading (just not too much) Jun 09, 2025

Show notes

The real fun of being a neuroscientist, and maybe the key to asking and answering new questions, is to think big and take intellectual risks.
