Nice, and it makes sense too. It's regression towards the mean (and away from being mean π)
Either you know you are a neuroscientist, or you don't. Either way, apply to join our lab before March 31 2026! :-)
Is mental imagery a single process?
Our meta-analysis of 46 fMRI studies suggests not.
We find a key divide between object imagery (visualizing an object in rich detail) and spatial imagery (mentally transforming objects).
This split mirrors the ventral and dorsal streams of vision
Also I love the simplicity and elegance of the interface
We are hiring passionate and curious researchers who can take initiative and work independently to tackle complex & challenging problems.
We have recently started a number of fascinating projects with real-world impact, such as studying the cognitive processes that drive literacy and numeracy in children, building neuroscience-inspired robots and performing human brain recordings in epilepsy patients to study vision and language.
Snapshot
We see and recognize objects effortlessly but vision is in fact a very hard computational problem. At the Vision Lab IISc, we are trying to unravel how the brain solves these complex problems by combining behavioral experiments and neural recordings with computational modeling.
Please circulate widely!

Today I received a note from a grad student who lives in Tehran. Her note gives you firsthand experience of what itβs like to live in a city that is being bombed, and what itβs like to be young and feel despair about your future.

Same to you! For those who use the dd/mm format, we have 22 July too π
Humanoid robots can run, crawl, and sort objects in flashy demos. So why canβt they reliably climb stairs or open doors?
@johnpavlus explains:
Join us in Woods Hole for Methods in Computational Neuroscience (MCN) at MBL (July 24βAug 21).
Four weeks of computational + systems neuroscience, hands-on training, and close interaction with an exceptional faculty.
DNN models of the brain are getting bigger. Are we replacing one complicated system in vivo with another in silico?
In new work, we seek the *smallest* DNN models of visual cortex, balancing prediction with parsimony.
It turns out these compact models are surprisingly small!

Come to IISc for open day, when all departments showcase fun demos!
Lovely piece! Charlie visited us in India back in 2011. I can see him come alive with your words.
Here's a striking visual illusion - the 9 purple dots.
Focus your eyes on the top left dot. That one is more purple than the others, right? Now try another dot... that one becomes the purple one! pubmed.ncbi.nlm.nih.gov/41744429/
Proud of my colleague Doug Weber for bringing in a much needed reality check to this discussion on the promise of brain implant tech.

Fantastic post by Colin Raffel, "We Are Over-Indexing on Paper Acceptance," drafted in May 2021 (!) but only posted now. The more things change..
Last sentence: "If you want to judge a researcherβs quality, the only meaningful way is to read their papers and judge for yourself."
Why do children struggle to recognise objects in cluttered scenes more than adults? Our new paper looks at the development of visual acuity and crowding across childhood, and the way the visual system fine tunes our ability to see detail: www.nature.com/articles/s41...
Like someone said on the thread, thanks. I hate it π
Bots have made their way to Prolific experiments. Our lab has stopped online testing of adults entirely now for this reason - we want to know if what we study is real. Probably data collected 2-3 years ago are ok, but moving forward we just can't know. www.pnas.org/doi/10.1073/...
The best nerdy valentine poem ever π
haha this is awesome!
