Check out our latest research drop! We show BLA dopamine signaling encodes the emotional weight of sensory transitions, but not the associative strength or value of stimuli. These signals dynamically rescale when the learning context changes: "this matters most!" www.biorxiv.org/content/10.1...

Ruben Ray Martinez: Footage shows US citizen shot by ICE agent in Texas traffic stop The Department of Homeland Security did not disclose Martinez was shot by one of its agents until almost a year later.

Newly released footage shows an ICE agent killing Rubin Ray Martinez, 23, in his car in Texas.

"He was shot at point-blank range through his side window by an ICE agent who was in no danger."

New preprint 🚨🧠🔬
@sophiepeterson.bsky.social + @margole.bsky.social dissect the roles of 2 major OFC subcortical pathways in context-dependent reward prediction.
TLDR:
OFC→CDS: critical for hierarchical gating of predictions.
OFC→MDT: more modest role, possibly limiting non-hierarchical predictions

At least yours has a number it seems! Mine is in limbo just as R0100000-00 in the system with no contact or anything. Chalked it up to general chaos but maybe given my request to go to a now canceled SS they have just delayed processing

No clue this seems related to originally CSR restructuring from years back?

Also this probably explains why my R01 in for cycle 1 has yet to receive a number or relevant information in a month with CSR redoing all these study sections

Blind refugee abandoned by Border Patrol dies in Buffalo. A nearly blind refugee abandoned by Border Patrol miles from his home dies in Buffalo after having been missing for nearly a week.

"Nurul Amin Shah Alam, a nearly blind refugee from Burma who Border Patrol agents dropped off at a doughnut shop Thursday and left to find his way home, 5 miles away, has been found dead."

To read the words is to damn all involved, from Trump on down.

Folks, -80 we have may have already bit the bullet and we need to evaluate options. What is the hivemind consensus of best -80 that doesn't die after 1 year and also wont cost me 50K.

"ICE operations in Pa. surge under the radar, destroying communities and lives"

Harrisburg, Scranton, Erie, Norristown. Even if ICE leaves Minnesota, they still need to be stopped

Ending this operation is not enough.

We need justice and accountability. That starts with independent investigations into the murders of Renee Good and Alex Pretti, economic restitution for businesses impacted, abolishing ICE, and the impeachment of Kristi Noem.

The headline should be, "DHS to keep 2,000 immigration officers in Minnesota."

Instead, it seems the entirety of the traditional media went with, "DHS to withdraw 700 immigration officers from Minnesota."

This presser worked like a charm.
