Representations of information value in mouse orbitofrontal cortex during information seeking
bioRxiv - the preprint server for biology, operated by Cold Spring Harbor Laboratory, a research and educational institution
www.biorxiv.org
Absolutely thrilled to share my postdoc work in the Axel lab. We found odor-evoked representations of the intrinsic value of information in mouse orbitofrontal cortex and showed that mice desire knowledge as its own reward. Now on bioRxiv! www.biorxiv.org/content/10.1...

Estrogen modulates reward prediction errors and reinforcement learning - Nature Neuroscience
Dopamine encoding of reward prediction errors naturally fluctuates over females’ reproductive cycles with estrogenic signaling due to reduced expression of dopamine reuptake proteins.

N-gram novelty is widely used as a measure of creativity and generalization. But if LLMs produce highly n-gram novel expressions that don’t make sense or sound awkward, should they still be called creative? In a new paper, we investigate how n-gram novelty relates to creativity.
