Thank you so much for the compliment! Indeed, we also think it aligns well with Gao&Ganguli's theory, while highlighting the role of state-feedback control in low-D dynamics. We have updated the preprint to include more comparisons with M1 recordings.

Latest from the lab: Laura Haetzel finds that excitatory transmission from auditory thalamus to tail of striatum is accompanied by a sparse inhibitory projection. This allows for state-dependent control of striatal output.

Live your life in such a way that when you die people don't literally rise from the dead to shit on your grave.
A Sharon Begley byline, almost 5 years after her death.
Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."
Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.

In the end, Andrew Cuomo’s long record was a gift to Zohran Mamdani. “What I don’t have in experience, I make up for in integrity—and what you don’t have in integrity, you could never make up for in experience,” Mamdani told Cuomo in a debate.
The Mamdani Era Begins
His opponents tried to smear him for his youth, inexperience, and leftist politics. But New Yorkers didn’t want a hardened political insider to be mayor—they wanted Zohran Mamdani.

My god this is for real one of the most incredible speeches I’ve ever seen by an elected US politician: ‘And if there is any way to terrify a despot, it is to dismantle the very conditions that allowed him to accumulate power. This not only how we stop Trump, it’s how we stop the next one.’
Mamdani: "We can respond to oligarchy and authoritarianism with the strength it fears, not the appeasement it craves. After all, if anyone can show a nation betrayed by Donald Trump how to defeat him, it is the city that gave rise to him."
