The origins of hallucinations are traced in specialized brain cells

Why do optical illusions work? The culprit may be a group of neurons in the visual cortex that help us fill in missing information.

@markjohnpost.bsky.social for @washingtonpost.com dives into the science and how it could help demystify visual hallucinations: www.washingtonpost.com/science/2025...

Researchers used lasers to record and stimulate the activity of neurons in mice to learn how the brain processes and interprets optical illusions.

When a neuroscientist is bored with chickens over the weekend…

Jérôme Lecoq @jeromelecoq.bsky.social · 18d

Yes, the chicken was doing some kind of turn every time on this day. It was fun to watch as it predicted the decision to ring.

Chickens are smarter than you might think....

🧠 Scientists shot lasers into brain cells to uncover how illusions work.

This study, published in @natneuro.nature.com, was supported by the @alleninstitute.org’s OpenScope program and could help us better understand neuropsychiatric disorders.

Thank you @fox13seattle.bsky.social for sharing a recent #OpenScope study on the science of illusions!

@hyeyoungshin.bsky.social shared how this research helps the world better understand how schizophrenia and other mental conditions work.

Open science is more than just datasets. It's also opening access to scientific facilities and pipelines.

OpenScope allows researchers from around the world to pitch experiments to be run – at not cost to them – in the Allen Brain Observatory.

Do you see a white square?

A new study, supported by our #OpenScope team, identified the key neural circuit and cell type involved with inferring details that don't exist in illusions like the one below.
