Nature research paper: Rewiring an olfactory circuit by altering cell-surface combinatorial code go.nature.com/3MbCoZT

Rewiring an olfactory circuit by altering cell-surface combinatorial code - Nature

In Drosophila, changing the expression of a small set of cell-surface proteins in just one type of olfactory neuron rewires its connections almost entirely to a new postsynaptic partner neuron type, altering the fly’s odour response and courtship behaviour.

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.

The first detailed look at how mosquitoes mate from @leslievosshall.bsky.social's lab reverses the assumption that male mosquitoes control the process, finding that a subtle female behavior dictates whether mating will take place or not. @currentbiology.bsky.social More here: https://bit.ly/4huwEpL
