Cool, looks like it ended up underestimating background firing rate and (perhaps thus) phasic responses…

Amazing study and the coolest results (from my point of view!) is that LC norepinephrine neurons projecting to the frontal cortex encode reward prediction error

I am livid that after less than a day, Vance et al are back empty-handed. "Marathon" talks?? They didn't even sleep on it and try again! Many thousands of lives, the world economy and world hunger, and more, hang in the balance, and they stopped trying after less than a day??

What a rotten failure.

We’re recruiting!

Exciting opportunities in our lab supported by a
@wellcometrust.bsky.social Discovery Award.

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

What cool tools you guys are making

Congratulations, very interesting results

The same, despite trying every possible route of calling for hours and hours

Agreed, and very interesting

what a nice study, congrats. will take a slide in my next BG teaching :) I wonder about the uniqueness of persistent confidence signals. Aren’t they as persistent as e.g. OFC confidence signals? Or am I missing something?

Actually the view from my office just got more interesting, as the official celebrations of the 200th anniversary now include a pirate projection saying "Free Palestine". Regardless of opinions, may UCL enjoy 200 more years of freedom of speech.

Out today in Neurophotonics, we show that cross-talk between the imaging laser and opsin in all-optical experiments can affect response dynamics beyond what has been accounted for. Imaging conditions subthreshold for evoking spikes can accelerate opsin desensitization:

Nice journal cover image!

Thank you

Thanks! we indeed found the dissociation interesting

Hah! thank Ross

It started with a surprising observation: we manipulated both sensory and reward expectation during a visual decision task. These had SIMILAR behavioral effects but OPPOSITE dopamine signals. These, other exp & modelling showed spatially overlapping dopamine SPEs & RPEs for shaping visual decisions

Dorsal striatal dopamine integrates sensory and reward prediction errors to guide perceptual decisions Perceptual decisions are shaped by expectations about sensory stimuli and rewards, learned through sensory and reward prediction errors. Dopamine is known to convey reward prediction errors that shape...

New preprint. We show that in addition to reward prediction errors (RPEs), dorsal striatal dopamine signals encode sensory prediction errors (SPEs), the difference between sensory prior & observed stimulus. www.biorxiv.org/content/10.6...

congradulations! you giving us good xmas reading homework!!

Very sad to hear

We tend to think of neurons as either excitatory or inhibitory, but some neurons chemically inhibit their downstream targets while electrically exciting their neighbors. What is gained by having an inhibitory neuron excite its neighbor?
