🎇 Excited to finally share JL Romero Sosa’s publication! Results are from single-cell imaging in different subregions of rat frontal cortex during ✨de novo learning. Spoiler: everything is not everywhere all at once www.nature.com/articles/s41...

Neural coding of choice and outcome are modulated by uncertainty in orbitofrontal but not secondary motor cortex - Nature Communications

Neural mechanisms underlying flexible learning and decision-making are not fully understood. Using single-cell calcium imaging, authors here found that neurons in orbitofrontal and secondary motor cortex exhibit complementary roles in reward learning, with neurons in the former exerting a sustained role in conditions of uncertainty.

I'm recruiting a PhD student to study how enkephalins affect cognitive processing in the rodent frontal cortex. The project uses pharmacology, multi-electrode recordings, and fiber photometry, and is funded by NIDA. Please share with trainees applying this cycle. Thanks!

I've never heard of these cases! I wonder if this is driven by spread into the reticulata or if this engaged the compacta lateralis dopamine neurons that regulate fear learning. Very profound!

Government shutdowns hit the DC area very hard. Consider throwing some money at Capital Area Food Bank-they are already struggling to keep up in the face of rising demand and food costs and reduced support. They will be busy in the days and weeks to come. give.capitalareafoodbank.org

Final version of this work is now live! Mitch developed this model and found that a history of chronic neuropathic pain in the SNI model facilitates pain-induced reinstatement of ethanol CPP in male mice.

www.sciencedirect.com/science/arti...

Graphical abstract from publication. Image summarizes findings that show that (1) male mice with a spared nerve injury (chronic neuropathic pain) exhibit greater sensitivity to pain-induced reinstatement of ethanol CPP and that (2) control and injured mice exhibit reinstatement following high force stimulation.

My experience as well, with the stated assumption that there are higher bars for the 2nd year applicants. Was my sense that program may have wanted/ preferred earlier apps for funding.

They have been slowly moving towards this (only one shot in year 1) over the past few years but have suddenly made the shift. Timing of this becoming a strict enforcement for eligibility given the year we are collectively having is deeply unfortunate.
