Herma of Demosthenes from the Athenian Agora, work by Polyeuktos, c. 280 BC, Glyptothek
^ Origin
In the earliest times Greek divinities were worshipped in the form of a heap of stones or a shapeless column of stone or wood. In many parts of Greece there were piles of stones by the sides of roads, especially at their crossings, and on the boundaries of lands. The religious respect paid to such heaps of stones, especially at the meeting of roads, is shown by the custom of each passer-by throwing a stone on to the heap or anointing it with oil. Later there was the addition of a head and phallus to the column,
which became quadrangular (the number four was sacred to Hermes).

 Name and origin
The earliest form of the name Hermes is the Mycenaean Greek
*hermahΓ£s, written e-ma-a2 (e-ma-ha) in the Linear B syllabic script. Other forms of the name of Hermes are Hermeias, HermaΓΆn,
HermΓ£n, Hermaios, and
Hermayos. Most scholars derive Hermes from Greek (herma),
'stone heap’,  Hermax, ('heap of stones'), hermaion, ('gift of Hermes'), hermaios hill were holy to Hermes.

Yeah dopamine encodes reward but what about when contingencies shift and behavior needs to be flexible? Turns out VTA GABA neuron activity plays a role, check it out in my first postdoctoral research article here!πŸ‘‡

Have you ever wondered why it’s called β€œThe Three Weeks” but sefira isn’t called β€œThe 7 weeks”? Sefira is literally about the 7 weeks, bain hamitzorim just happens to be 3 weeks long!

This FDA hearing is a sham. There is enough stigma and confusion about treatment for medically-based psychiatric issues. These lies will result in deaths of people who have treatable illnesses.

Do I know anyone who has worked with Peter Carruthers, Joshua Knobe, Hakwan Lau, or Thomas Metzinger?

I am looking for who would be a good collaborator on an experimental philosophy project.

The group also attacked financial aid programs at Hopkins, including one given by alum Michael Bloomberg, making the medical school free to attend for those from families making under $300,000 a year. About two-thirds of Hopkins medical students, according to the university, qualify for the scholarship.
But the conservative group argued that "it is well recognized that race and ethnicity are inseparable from socioeconomic status," adding that "Johns Hopkins masks racial preferences behind income thresholds."

New from @dralexharris.bsky.social, Ula Skupio, and myself in @cp-trendsneuro.bsky.social: a long in the works review trying to untangle what stress is doing in the VTA, and what the piles of confusing data might teach us about what the VTA is doing at all.

Stress is complicated, right?

Ula Skupio @ampolter.bsky.social & I had a hard think about the way acute & chronic stress impacts the different neural populations in the VTA & I’m really pleased with what we came up with.

Just published in TINS. Check it out!
