Thank you for the great summary, @thetransmitter.bsky.social, and the shout-outs from scientists we admire. There is so much we don’t know about how sex hormones modulate behavior and we’ll keep exploring!
“It’s giving mechanistic insight into how estrogen modulates reinforcement learning—all the way down to the molecular mechanism,” says Ilana Witten.

Sex hormone boosts female rats’ sensitivity to unexpected rewards
During the high-estradiol stages of their estrus cycle, female rats learn faster than they do during other stages—and than male rats overall—thanks to a boost in their dopaminergic response to reward…

So excited to see our latest paper out today in @natcomms.nature.com! Studies led by the amazing @margestelzner.bsky.social www.nature.com/articles/s41.... VTA GABA neurons have a unique role in economic decision making - they integrate reward seeking motivation and the current cost of seeking
Ventral tegmental area GABA neurons integrate positive and negative valence - Nature Communications
The role of ventral tegmental area GABA neurons in behavior is unclear. Here, authors show that VTA GABA but not dopamine neurons integrate positive and negative valence to encode motivational conflic...

Characterizing neuronal population geometry with AI equation discovery
The visual cortex contains millions of neurons, whose combined activity forms a population code representing visual stimuli. There is, however, a discrepancy between our understanding of this code at ...
