Semi-hypothetical question. Would you find it interesting if there were time cells in primary visual cortex?
Let's say you do an experiment recording from a bunch of neurons after you present a stimulus. You find that the neurons fire in a reliable sequence so you can decode time since the stimulus was presented. The sequence starts out fast and then slows down smoothly so that you can decode recent time better than more distant time. Cells that participate in the sequence also distinguish the identity of the stimulus, so the population is a distributed code of what X when.
So far this is exactly like time cells people see in hippocampus, PFC, striatum etc. Time cell sequences go from about 200 ms post stimulus up to at least a minute.
But this population was recorded from (mouse) primary visual cortex and the sequence starts way sooner, 50 ms up to about 200 ms (the longest that could have been observed in this experiment.
Big deal? Obvious? Do we know this already about visual cortex? #Neuroscience#TimePerception#Vision
Apple may regret picking the Vision Pro name for its new headset, as a rival firm has already trademarked it. And it’s not the only headache Apple is facing.
My wife and I tested our new old camera from 1954 that produces square images on a 35 mm film, so on a roll of 36 you can squeeze in over 50 images! (We used the cheapest color film available) 📸
I'm back to living after a tough experience. This time a cute bunny, another photo from the same roll as before, more material already waiting to be published! 😊

I'd love to chat with a #vision scientist about why they think some things have a "right side up" and not others. writing is strongly orientation sensitive, but brain doesn't seem to care when recognizing and processing lots of other complex objects. seems like a weird gap in my understanding and a really basic question. #neuroscience#neuro@neuro@neuroscience

So....top of the line Varilux progressives for about $478 (w/ insurance, lenses only) or good ol' Costco frames and prog. lenses (proprietary?) for less than 300.?
That's my current dilemma.
I dunno about you but I’m not interested in the #Apple#Vision until there’s a mod for the Apple video conference avatars that gives everyone big floppy dick nipples.

Don't know why we have a double checkmark in the Mastodon Advanced Web Interface in the Notficatins column. As someone who takes reading glasses on and off it makes me reach for my eyeglasses even though I’m wearing them. Sort of silly and very distracting. #Mastodon#eyeglasses#vision#UI

The human eyes have "only" 3 different colour receptors, so multiple spectra can be perceived as the same colour.
(And this without considering all the ways the signal is processed before you actually "see" it.) #Optics#Colour#Color#Vision
The screenshot below features Patrick Lichtsteiner and his work on mimicking retinal circuits in the design of the dynamic vision sensor (DVS), an event-based camera where the log difference of light intensity at time t and t-1 is emitted (the event), rather than a typical camera frame. This has extraordinary implications for visual processing, data transfer bandwidth and data storage.
