In this study, we found a feeding rate-dependent neuronal modulation in the mouse olfactory cortex (aPC). When mice are binge feeding, the whole olfactory cortex is shutting down, while we can see clear neuronal responses during slow feeding. This modulation is not observed in the gustatory cortex, another main sensory modality in flavor perception. We dived much deeper into the potential mechanisms including olfactory bulb inputs and local GABAergic interneurons in the aPC (see Fig. 3 in the paper). 

​

We further found a correlation between binge-induced aPC suppression and mice's appetite. Enhancing the aPC suppression through closed-loop optogenetics we can increase food intake in mice!

​

Overall, we described a novel behavior-dependent sensory modulation in the olfactory cortex, and such modulation has an active role in regulating feeding behaviors.

We (open & reproducible courses lecturers and brainstorming organizers, marked with *) invited our past course participants for a brainstorming event for following up on what practice they have implemented in their own research and what are the challenges they faced. We distilled the discussion into this "10 simple rules" paper so researchers can find it easier to navigate what to do after participating in training courses.

​

This is a meta-research paper collaborated with the eLife community ambassador program. We performed meta-research on papers from three biomedical fields (Plant Biology, Cell Biology, Physiology) and assessed the reporting quality of biomedical images (eg. scale bar, color, annotation...).

​

We also provided a clear step-by-step guideline on how to make clear and informative image-based figures for biomedical research articles.

​

During postnatal development, neurons' morphology changes drastically. Here, we found the dendrites of layer 2a and layer 2b excitatory neurons in the mouse piriform cortex have very different morphology during the postnatal development regarding their length and branches. 

​

We further identified a potential mechanism that during the early critical period, NMDA-mediated dendritic spikes are only observed in the distal apical dendrites of layer 2b piriform neurons, which select the dendritic branches to survive during developmental pruning in apical dendrites.
