Kinda reminds me of this...
Come to the CRaNE conference in Atlanta in May. Some folks I know will be speaking about spatial navigation (one of them is me!)
My main scenario of concern is that D senate wins in red states (OH, GA, TX, AK) will *not* be certified by R election authorities.
Our results build on previous cool work by @carolinerobertson.bsky.social @nancykanwisher.bsky.social @annamynick.bsky.social @samberens.bsky.social @aidanhorner.bsky.social @neurosteel.bsky.social, among others.
Our new paper in @sfnjournals.bsky.social shows different neural systems for integrating views into places--PPA integrates views *of* a location (e.g., views of a landmark), while RSC integrates views *from* a location (e.g., views of a panorama). Work by the bluesky-less Linfeng Tony Han.
Some nice publicity on our recent "Neural compass" paper, from @sfnjournals.bsky.social.
This is a great Postdoc opportunity at UPenn, for recent Ph.D.s who want to collaborate with CogSci (psych, neuro, ling, philo, cs, etc.) faculty and have their own research direction.
That was my breaking point too.
Penn faculty senate passes resolution urging the Penn admin to reject the compact, as MIT and Brown have already done.
It's really not clear to me how U.S. democracy gets out of this one alive. Dems would need +6 on the popular vote to have a 50/50 chance of controlling the House. That's a recipe for a one-party state.

The administrations "invitation" to 9 universities is in fact just their latest attempt at extortion. I urge my @upenn.edu colleagues to sign the petition below.

Interested in navigation, VR, fMRI, aging? Here's a great postdoc opportunity in @stevenmweisberg.bsky.social's new lab at U Texas Arlington.
Our new paper Cognitive maps for hierarchical spaces in the human brain is out in Cerebral Cortex! Work by first-author Michael Peer.

Thanks for the post. You knew that it was out before we did!
I downloaded an electronic version this summer and started to read it...many, many good chapters. I can highly recommend!
This work builds on an extensive line of previous fMRI studies on heading codes (by @wolberslab.bsky.social, @doellerlab.bsky.social, @matthiasnau.bsky.social, @hugospiers.bsky.social, Baumann & Mattingley, Kim & Maguire + others). It was a LONG time in the making so we are thrilled to see it out!!!
When we looked at the model weights, we found that voxelwise peaks were distributed across all directions (like a compass), but the voxelwise troughs tended to be aligned with the main axis of the space. The latter result was unexpected and we think it’s pretty cool!
These heading codes generalized across perceptually different versions of the city, different locations in the city, and different phases of the taxi-cab task—thus fulfilling the expected characteristics of a “neural compass”.
We found heading-related response in retrosplenial complex (RSC) and superior parietal lobe (SPL). This is nicely consistent with previous studies that observed heading codes in these regions using trial-based designs.
How do we keep track of our sense of direction during navigation? Head direction cells in rodents are well-studied, but what about humans? To answer this question, we used an encoding model to analyze fMRI responses while participants performed a “taxi-cab” task in a VR city.
Our new paper, “A neural compass in the human brain during naturalistic human navigation” is out in @sfnjournals.bsky.social! First-author @zhenganglu.bsky.social led the charge, with Josh Julian and collaborator @gkaguirre.com.

"Things the reviewers care more about than we do" + "Things we care about, but we're pretty sure you don't"
This is some very cool work that @ainsleybonin.bsky.social did at Colby College, working with Derek Huffman. If you are fortunate enough to be at CogSci, give it a look.
The mass starvation & killing of Palestinians in Gaza at the hands of the Israeli gov’t is a chillul hashem, a desecration of God.
Jewish leaders who criticized Zohran Mamdani for three words he doesn’t use should raise their voices loudly here as well.

Supposedly AI is going to take over the world, but I just spent 30 minutes unsuccessfully trying to get ChatGPT to change the axis labels of a chart. Which it kept failing to do, each time saying "now I've done what you asked!" without changing a thing. So I am skeptical.
This little document is immensely helpful.
Super cool! Sending you best wishes for a safe trip and many moments of brilliant insight.
Democracies do not use their military to try and intimidate their own citizens with “shows of presence”.
This is fascism.
We’ve bombed Iran. And dismantled our joint terrorism task force. And sent a third of the FBI to help ICE. And gutted the National Security Council. And a drunk guy is in charge at the pentagon. And our intelligence allies probably won’t share intel with us. Because people couldn’t vote for a woman.
