The global neuronal workspace (GNW) is currently the best documented neuroscience mechanism by which conscious processing arises in the human brain — and now Anthropic researchers have discovered a similar workspace inside their large language model !

How might animals perceive time? Ishan Singhal describes how illusions might hold the key, in today's @theguardian.com (based on our recent @cp-trendscognsci.bsky.social which he led) @singhal.bsky.social www.theguardian.com/commentisfre...
Why would we show an optical illusion to a monkey or a sparrow? To learn how they experience time, of course | Ishan Singhal
Animals may inhabit the same world as us, but new research shows how their perceptions of what is around them differs, says research fellow Ishan Singhal

for undergrads getting their degrees this Fall: if u're computationally savvy & wants to get into cog neuro -- instead of taking up lab manager / RA positions, why not come to Korea & get a master's degree instead?
it will be all paid for w/ stipend, of coz. why would u pay for a master's degree??

First media coverage I ever received for a paper I wrote! It was a huge surprise and honour to be interviewed by @science.org
Do animals perceive time differently from humans?
Science chats with @singhal.bsky.social—a researcher whose team is using “timescapes” to understand how nonhumans experience the world. https://scim.ag/4xFs4wM

what do researchers mean when they say they measure 'consciousness'? do they mean 1) subjective experiences, or 2) just general cognitive capacities?
to those who say 1, perhaps they think Alzheimer patients are zombies, or they are actually confusing 1 with 2

How does blood flow relate to brain activity? We discovered that it reflects two neural populations affected oppositely by arousal. Together, they explain neurovascular coupling in all brain regions and brain states!
