A bit of a late post, but defended my PhD earlier this week! One of the most important moments of my life, and thanks to all that have helped me during my journey!

Divisive Normalization Circuits Faithfully Represent Auditory and Visual Stimuli biorxiv.org/cgi/content/sh… #biorxiv_neursci

Happy Halloween!

Our paper on a Drosophila visuomotor circuit was published in Current Biology. Congratulations Hyosun Kim and all the authors for your hard work for many years. This one is special as it is the first research project that was carried out entirely at Hanyang Univ..

Making the odorant world intelligible - How its semantics can be characterized. doi.org/10.1371/journa… models the identity of an odorant object as semantic information and the onset/offset timing events as semantic timing.

BrainMapViz now features Ventral Nerve Cord (VNC) connectomic dataset. Check it out and start exploring at manc.neuronlp.fruitflybrain.org

BrainMapViz now features FlyWire dataset. Try out the demos and begin exploring the near-complete Drosophila brain connectome at flywire.neuronlp.fruitflybrain.org

BrainMapViz of Fruit Fly Brain Observatory now features an updated Drosophila L1 Larva Connectome (L1EM) dataset with over 3000 neurons (including part of larva ventral nerve cord). Try out the demos and begin exploring at larva3000.neuronlp.fruitflybrain.org

BrainMapViz of the Fruit Fly Brain Observatory now features the Drosophila Optic Lobe connectome, featuring mostly columnar neurons in the medulla, lobula and lobula plate. Try out the demos and begin exploring at opticlobe.neuronlp.fruitflybrain.org

Two cascaded divisive normalization processors, carrying out intensity/contrast gain control and elementary motion detection, respectively, model the robust motion detection of the early visual system of the fruit fly doi.org/10.1007/s00422…

Gal Haspel @[email protected] and friends are calling for papers at JNP Send your research, reviews, or opinion papers!

We have joined a consortium with 8 other NYC graduate engineering programs that allows doctoral students at any of the affiliated programs to take courses at each other’s institutions.

Might not be flowers for Valentines day but snapshot 783 is at least as beautiful if not more 😀

Awesome! The 4th NSF-funded workshop on the Functional Logic of Neural Circuits, in San Juan PR, was as fantastic as the first three :) sites.google.com/njit.edu/diamo… Lots of interesting discussions and ideas to think about. More tags below:

BrainMapViz now features the Optic Lobe connectomic dataset, containing over 50,000 neurons in the right optic lobe. The dataset features indexable columns, strata, layers and hexagonal rings. Check it out and start exploring at opticlobe.neuronlp.fruitflybrain.org

Modeling and characterization of pure and odorant mixture processing in the Drosophila mushroom body calyx doi.org/10.3389/fphys.… (i)Odorant stimuli are modeled by their identity (semantics) and concentration amplitude (syntactic) information content.

Modeling and characterization of pure and odorant mixture processing in the Drosophila mushroom body calyx doi.org/10.3389/fphys.… (ii)The Antennal Lobe and Calyx jointly separate the odorant semantics from syntactic information.

Modeling and characterization of pure and odorant mixture processing in the Drosophila mushroom body calyx doi.org/10.3389/fphys.… (iii)The semantics info is mapped by the Calyx into a first spike sequence for easy memory access in the Mushroom Body.
