Rachel Essner and the team deserve huge congrats for this opus on integrative brain-to-body signaling in the parabrachial nucleus. Now improved and published! Check it out.

Imaging activity in many defined cell types is now easi(er) using conventional 2p and confocal microscopes. 3000-5000 imaged neurons per recording, 78% matched to post hoc 3D EASI-FISH. We wanted this to be useful, affordable, and reliable. Jonna and an incredible team made it happen. Check it out!

Peter Kalugin's paper on optical tracking of up to ten neuromodulators simultaneously is out in Neuron with some cool new results, including quantitative demixing of norepinephrine and dopamine concentrations. Please check it out!

Excited to share my PhD paper! In it, we use targeted 2-photon optogenetic stimulation to determine how V1 activity is read-out in a detection task. We found that network influence, not visual coding properties, predicted the impact of ensembles on behavior - contradicting our expectations (1/5).

Congrats Marta on a very strong effort!

Wild! Stephen, Praneel and their team use fluorescence lifetime imaging and various manipulations to show that, in male mice, both mating drive and hypothalamic tonic dopamine release drop after a successful mating and gradually recover over the next week, paralleling the recovery in sperm count.

Disruption of visual cortical activity and offline reactivations of recent salient experience in the hours following training on a task associating cues with outcomes completely blocks across-day learning! Exciting work by Kristian, Marianne and their team!

We previously showed that specific hypothalamic neurons get more and more activated by each bite of food until they put a brake on homeostatic feeding. Here, we find that this brake is already on at the start of a meal in obese mice on a high-fat diet. Congrats to Marta, Stephen and the whole team!

A drop of milkshake takes a wild ride as it passes through the body. Rachel and Kiersten and the team came up with cool strategies for visualizing food passing through the mouse GI tract and mapping the activity of the same 100s of brainstem neurons across weeks during feeding and other behaviors.

We lack tools to rapidly track >1-2 changing signals in brain fluids. Peter Kalugin and an amazing team begin to address this challenge with simultaneous, real-time tracking of many (10+) neuromodulatory signals using Multiplexed Optical Recording of Sensors on a micro-Endoscope. Feedback welcome!

Stephen Zhang and the team found that in vivo peptide release and signaling gradually enhances responses of satiety-promoting hypothalamic neurons to each bite of food. These consequences of each bite take minutes to manifest, and could help explain why slow eating enhances satiety. rdcu.be/dZlI3
