Congratulations to Greg, Melissa, Katie, Philippe and Tom on the great work!

In the fly mushroom body, excitatory Kenyon cells receive feedback inhibition from the APL neuron. When Kenyon cells are over-activated, APL compensates by reducing its activity. But this decreases inhibition onto Kenyon cells, conflicting with the Kenyon cells' attempts to reduce their activity.

Conflicting adaptations in an inhibitory feedback circuit Abstract figure legend We studied activity-dependent adaptation in the fruit fly Drosophila’s memory centre, the mushroom body. Here, excitatory Kenyon cells (KCs) receive feedback inhibition from th...

Oxygen-free metabolism in the bird inner retina supported by the pecten - Nature While the photoreceptor outer segments in the bird outer retina have access to oxygen, the inner retina operates under chronic anoxia, supported by anaerobic glycolysis in the retinal neurons.

Birds have a thick retina devoid of blood vessels - so how do they ensure sufficient oxygen availability?
They don't - neurons rely on glycolysis, metabolizing glucose released from the pecten.

Insane new study that includes comparative data on lizards and crocs.🧪

NIBAI 2025 Workshop on the Nature of Intelligence was held in Sheffield, bringing together over 70 participants from diverse backgrounds in neuroscience, animal cognition, philosophy, and AI.

An optical brain-machine interface reveals a causal role of posterior parietal cortex in goal-directed navigation Relating neural circuitry to behavior is challenging due to closed loop interactions between neural activity, actions, and sensations.

We all know that correlation doesn't imply causation. So we took some correlations and tested if they were causal. Here's what happened:

This was the work of Katie Greenin-Whitehead and Melissa Tan in my lab, with @eyalrozenfeld.bsky.social and @mosheparnas.bsky.social who did the electrophysiology, and Anthony Moreno-Sanchez, Kurtulus Kullu & Jessica Ausborn who did the compartmental model. Thanks for the super collaboration!

Excited to share our latest work - expressing the bacterial sodium channel in fly Kenyon cells surprisingly *decreases* their excitability, thanks partly to decreased endogenous sodium channels. This prevents learning and decreases odor-evoked calcium influx doi.org/10.1113/JP28...

Stereo olfaction underlies stable coding of head direction in blind mice - Nature Communications Stereo olfaction involves comparing odor differences between the two nostrils.

🚨new paper alert
Blind mice use stereo olfaction, comparing smells between nostrils, to maintain a stable sense of direction. Blocking this ability disrupts their internal compass.
