lab preprint! Interopceptive predictions are central to many brain-body interactions theories, but it's unclear if/how they affect bodily physiology. We (fearless Einav Litvak et al) show that insular cortex predictions are essential for glucose homeostasis-THREAD.. www.biorxiv.org/content/10.6...

Why do old books smell?

"That "old book smell" brings back so many memories, but what creates that distinctive scent?"

one of the coolest things about ChatGPT is how you can actually just never use it. you can fill your whole entire life with simply not once using it. it's incredible.

Effects of Cervical and Auricular Vagus Nerve Stimulation on Electrocardiogram and Electroencephalogram in Rats Vagus nerve is the longest cranial peripheral nerve of human body comprising both sensory and motor nerves. Due to its extensive distribution throughout the body, vagus nerve stimulation (VNS) has bee...

A comparison of cervical and auricular VNS in rats shows that only cVNS alters heart rate (likely due to efferent effects). aVNS is not inferior to cVNS in terms of modulated EEG power (peaks in somatosensory cortex).

Finland ends homelessness and provides shelter for all in need - scoop.me In Finland, the number of homeless people has fallen sharply. Why? The country applies the "Housing First" concept agains homelessness.

“In Finland, the number of homeless people has fallen sharply. Those affected receive a small apartment & counselling with no preconditions. 4 out of 5 people affected make their way back into a stable life. And all this is CHEAPER than accepting homelessness.”

It costs a lot less to house people.

The work I love most blends learning about theory with answering something practical. Here, we got to hit both nails on the head!

Come for the "Does implicit bias change generalize across implicit measures?" Stay for the "Can we reduce anti-fat bias?" Or vice versa. Just read the paper; it's great!

A neural mechanism for learning from delayed postingestive feedback - Nature Illness signals from the gut reactivate and strengthen flavour representations in the amygdala to support learning from delayed postingestive feedback.

How do we associate the flavors we experience during a meal 🍽️😋 with postingestive effects like food poisoning 🤢🤮 that arise much later?

Our answer in @nature.com this week: Illness signals from the gut reactivate and strengthen flavor representations in the amygdala.

Summary of the study. A: The schematic shows the experimental procedure, illustrating five weekly lab visits followed by 2 MR visits labeled from S1 to S7. After the first session (S1), participants undergo four weeks of continuous glucose monitoring (CGM) combined with ecological momentary assessment (EMA). B: The CGM system uses a small flex sensor placed at the posterior upper arm that is inserted in the subcutaneous fatty tissue. The glucose sensor, positioned beneath the skin surface layers (epidermis and dermis), measures glucose levels in the interstitial fluid within the subcutaneous adipose tissue. The data is wirelessly sent via near field communication (NFC) to the FreeStyle Libre 3 app on the participant’s cell phone. The accuracy of the sensor concerning capillary glucose has been validated (Alva et al., 2022). C: Participants rate their metabolic and mood states twice daily using a visual analog scale (VAS), ranging from 0 (not at all) to 100 (very).

Do you get in a bad mood if you are hungry? Over 4 weeks with EMA+CGM, we tested if mood shifts are subconsciously driven by glucose levels or ratings of metabolic state #neuroskyence 🩺

But Vought and Rufo are missing something.

We aren't cowards.

And we know we are not the enemies of the American people either, much as these ideologues might like to claim that.
