"Olfaction is at once both the primitive sensory modality and one of the hardest to understand, in large part due to the complexity of olfactory stimulus space. Whereas light and sound are easily ordered along natural physical axes that are reflected in their respective sensory codes, the organizational axes of odor space are not obvious."

More than happy to land here! I am a neuroscientist interested in the dog-human bond. 😃 💞 🐶 Using fMRI, I help uncover how dog brains perceive their social world.


I am not alone in this endeavor. Besides brilliant human colleagues worldwide, I have two amazing furry colleagues, Odín and Kun-kun.

Hearing is believing: Sounds can alter our visual perception https://www.psychologicalscience.org/news/news-release/2022-december-sounds-visual-perception.html

Question for the vision scientists out there. Do we know whether mice experience binocular rivalry (or similar bistable phenomena)? After a superficial search, I see that they have 40 degrees of binocular vision so it seems plausible but can't find anything on it specifically.

Hi all, my #introduction! I lead a #neuroscience research lab at Emory University called the Perception and Action Lab. We study how the brain allows us to actively explore and learn about the world through body motion. We're particularly interested in modeling and understanding distributed computations across multiple brain areas, and how these computations change during hearing loss and other conditions. I mostly post about work but sometimes other things too!

Who are you when you're split in two? When it comes to your brain, two halves do not make a whole. Learn about how the two halves of your brain communicate and what happens when you cut your brain in half in this week’s article by Barnes Jannuzi.

Important note for educators about now: it looks like GPT-2 output detectors can detect #chatgpt output pretty well.
https://huggingface.co/openai-detector

That is a damn cool view.

One straightforward way of dealing with systems like #ChatGPT or #Galactica in #higherEd is to directly confront students with an LLM-generated answer and have them critique it.
This is in fact be much better aligned with what we want to teach. Remembering and recalling facts isn’t an important skill anymore, but #criticalThinking is essential for a future in which graduates will work side by side with “#AI.” #constructiveAlignment

#climatecrisis Wonderful interview of @WanderingGaia on Nature Podcast. It's inspiring to hear someone talk so positively about solutions to the #climatecrisis - social solutions which are practical and rapid such as managed migrations followed by concerted efforts to restore abandoned areas. Hope remains.

Really interesting results. I would not have guessed. But great, yes, let’s emphasize the science (while doing the others too). And interact more around science topics. That’s also what I want to see more of. And I’m hoping to help by facilitating and participating in more interactions here. Join me!

After an evening's thought, I see that these systems pose challenges when writing open-book, open-internet exams.

(I am unreservedly opposed to using any sort of digital spyware —e.g. Proctorio—for reasons that I explain in this twitter thread: https://twitter.com/CT_Bergstrom/status/1322369355930165248)

My hope is that as we come to understand better what these systems can and can't do, we can learn to write questions that cannot be answered by AI, and that in doing so we will learn to write better questions in general.

A big jump in prosthetic vision https://scopeblog.stanford.edu/2022/12/02/a-big-jump-in-prosthetic-vision/ BTW, the legal blindness definition in the US uses an acuity threshold of a harder to surpass 20/200, not 20/400, whereas the WHO uses an acuity threshold of 20/400 for blindness, but that is not a legal one; #retinal #implant, #AMD, #Pixium #Vision

This short piece by Kevin Mitchell on how Free Will might be compatible with what we know about the brain is compelling (although early undergrads might need a bit of help with it).
