Cortical α-synuclein pathology induces cell autonomous neuronal hypoactivity and compensatory circuit changes in a model of early Lewy Body Dementia
Cognitive impairment is a common non-motor symptom of Parkinson's disease (PD) and a defining feature of Dementia with Lewy Bodies (DLB). Although many cognitive domains can be affected, impairments i...

🎇 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.

Here is the formal letter the NIH sent today to UCLA Chancellor Julio Frenk.

“These projects are fully reinstated, and the letter dated July 31, 2025 is rescinded without conditions. Funds will be made available immediately and are no longer suspended, terminated, or restricted.”

In the early years of my PhD I remember being asked if we'd ever treat or cure diseases like HIV or Huntington's. I remember saying maybe, but not knowing if I believed. Seeing research pay off as real impact on human lives is - incredible.

BREAKING: A federal judge has ordered Trump to restore $500 million in frozen UCLA NIH grants. The same judge, Rita F. Lin, previously ordered all UCLA NSF grants reinstated. Lin has now nearly entirely reversed Trump's July de-funding of UCLA research: www.latimes.com/california/s...

This was a great event I was happy to help organize it. It was so heartening to see so many folks put their time and effort into making it happen. At the same time, it is eye opening to realize how little most folks out in the public, including our own backyard, know about what is going on.

🚨 150 University of California law professors (and counting) have now signed this open letter to the UC Regents and other officials, explaining the flagrant illegality of the Trump Administration’s UCLA funding cut offs, and urging the UC to fight back. sites.google.com/view/uclawfa...
Dear President Milliken, Regents, and Governor Newsom, As faculty members of University of California law schools, we endorse Governor Newsom's commitment to resist the Trump Administration's unlawful actions taken against the University of California, Los Angeles. The Governor is on firm legal ground. The Trump Administration's termination and suspension of federal funds has violated Title VI of the Civil Rights Act of 1964 in numerous ways. Governor Newsom and the University of California Regents will protect the vital interests not only of Californians but of all Americans if they defend the University of California's rights. The U.S. Department of Justice notified UCLA on July 29, 2025, that it had found that UCLA had "violated its obligations under the Equal Protection Clause of the Fourteenth Amendment and Title VI of the Civil Rights Act of 1964." Chancellor Frenk subsequently announced that "the federal government claims antisemitism and bias as the reasons" for federal grant terminations. UCLA faces losses of at least $584 million, funding that has supported vital research on matters ranging from treatments for pancreatic cancer to advances in online security. The Trump Administration has made no pretense of following the law. Title VI permits a federal agency to terminate funding only if it has found that the particular program receiving that funding has violated the law's non-discrimination provisions. Funding cannot disappear just because the agency's policy or political preferences differ from the institution's. Moreover, the agency can act only after following specific procedural steps. Importantly, Title VI requires a formal administrative hearing—a proceeding much like a trial-before the agency can terminate funding. At the hearing, the agency would have the burden of proving the university's alleged violations of Title VI before an impartial decision-maker. If the agency prevails at the hearing, the university or other interested persons could appea… factually supported and consistent with civil rights laws. Without the steps Title VI requires, there is no protection against an administration alleging discrimination as a pretext to force compliance with its policy or partisan preferences. Title VI's procedures guarantee the constitutional due process requirement that no person can be deprived of liberty or property without fair notice and opportunity to be heard. They protect the university and its members' academic freedom, an endowment essential to scientific research, intellectual discovery, and open debate. We are deeply committed to the core principle of non-discrimination codified in Title VI and in the Constitution's Equal Protection Clause. The principle that no person may suffer discrimination because of race, color, or national origin protects equality and ensures fairness in political as well as social life. Allegations of discrimination deserve serious and careful consideration and, where established, effective redress. But this enforcement effort must follow the law. We urge Governor Newsom and the UC Regents to continue to stand up for the fundamental principles of the rule of law, due process, and equal protection. A defense of the University of California's rights in court will model respect for these bedrock principles of equality and fairness, and it will ensure that the government honors them. The Trump Administration's failure to abide by the law subverts these principles by denying the University of California a fair opportunity to contest the government's charges of unlawful discrimination before an impartial decisionmaker. It is precisely because we cherish the principles of the Civil Rights Act and the Constitution that we encourage Governor Newsom, the UC Regents, and the University of California to fight back. Through its grantmaking powers, the federal government wields vast influence over social and economic life. If not held to account by the procedural protections enacted by Congres…

My lab’s major NIH grant was among those blocked in the attack on UCLA. Because our lab website discusses inclusivity? Because this grant had a diversity-based supplement? Simply because I work at UCLA? Who knows. Feeling a strange mix of unsurprised, furious, and numb.
