Democracy seldom collapses in plain sight; it erodes in the gray areas. Its decline begins at the uncertain boundary between what is clearly lawful and what can be made to appear so through interpretation. Democracy dies in the gray.
(Also true on university campuses)

Academic friends,
It's beyond heartbreaking to watch what's unfolding in Iran & the region.
A few of us drafted an open letter calling for protection of civilians & of educational, research, medical & cultural institutions.

Who would have thought? Tune in, and Tucker Carlson has more to say about this than our scientific community... Forget Tucker, even MTG and Alex Jones are on the right side of history with this... While Barack Obama talks about college basketball...

You see what happens, Larry? This. Is what happens, Larry. When a king goes insane. Destruction of a whole civilization.

What is the 25th Amendment for, if not for a moment like this, when a king has totally lost it and gone bananas?

"Whole civilization will die tonight". Thank you for your attention to this matter.

... But I only study rats and viruses.
They will come for you, too, in time. He promised to send the country back to the Stone Age, where there was no Institut Pasteur. Or maybe the war criminal has 'credible' intel that the Ayatollah was living under the institute...

100+ year old Pasteur Institute in Tehran was a premier infectious disease research institute and vaccine manufacturer

It is a reason Iranian kids like me born in 60s had access to measles vaccines soon after they were developed in the west

Pasteur Institute of Iran, founded in 1920 now destroyed by Israel-US bombing😞

It played a pivotal role in developing vaccines & public health services, for over a century, now gone😞

A few days ago a pharmaceutical plant was bombed, accused of making anesthetic fentanyl

Bombs keep falling from the sky. Some are closer to your home, and you can hear them. This one fell 6 blocks from my old house in Tehran. My childhood friend's mom was collateral damage:she was bombed, in passive voice. No one drops the bombs. No one pays for them to drop. No one is held accountable

I wonder what the carbon cost of the US/Israel attack on Iran is. Someone should write a grant to study this... For the environment

I suppose there are still living, dear Jeffreys who hover over our institutions, and some colleagues are continuing to woo them for a fistful of dollars. It's like the ending of Jurassic Park. You think you destroyed the island, but dinosaurs are still out there. This movie has a sequel.

Thrilled to finally share this work! 🧠🔊

Using a new reinforcement-free task we show mice (like humans) extract abstract structure from sound (unsupervised) & dCA1 is causally required by building factorised, orthogonal subspaces of abstract rules.

The current system is working exactly as designed. It destroys critical thought to protect capitalist hegemony and utilizes disciplinary techniques to mold compliant, indebted subjects. It is a factory for the production of inequality that only societal change can address imho…

A synaptic locus of song learning Learning by imitation is the foundation for verbal and musical expression, but its underlying neural basis remains obscure. A juvenile male zebra finch imitates the multisyllabic song of an adult tutor in a process that depends on a song-specialized cortico-basal ganglia circuit, affording a powerful system to identify the synaptic substrates of imitative motor learning. Plasticity at a particular set of cortico-basal ganglia synapses is hypothesized to drive rapid learning-related changes in song before these changes are subsequently consolidated in downstream circuits. Nevertheless, this hypothesis is untested and the synaptic locus where learning initially occurs is unknown. By combining a computational framework to quantify song learning with synapse-specific optogenetic and chemogenetic manipulations within and directly downstream of the cortico-basal ganglia circuit, we identified the specific cortico-basal ganglia synapses that drive the acquisition and expression of rapid vocal changes during juvenile song learning and characterized the hours-long timescale over which these changes consolidate. Furthermore, transiently augmenting postsynaptic activity in the basal ganglia briefly accelerates learning rates and persistently alters song, demonstrating a direct link between basal ganglia activity and rapid learning. These results localize the specific cortico-basal ganglia synapses that enable a juvenile songbird to learn to sing and reveal the circuit logic and behavioral timescales of this imitative learning paradigm. ### Competing Interest Statement The authors have declared no competing interest. National Institutes of Health, K99 NS144525 (DCS), F32 MH132152 (DCS), F31 HD098772 (SB), R01 NS099288 (RM), RF1 NS118424 (RM and JP)

Where does learning through imitation happen in the brain?

In juvenile zebra finches, we pinpoint a synaptic locus of song learning in a cortico-basal ganglia circuit and leverage this localization to measure the timescale of consolidation and make birds learn faster! #neuroskyence (1/14)
