What's the relation between voltage and calcium in dendrites? Xiang Wu studied this in CA2 hippocampal pyramidal cells in behaving mice. www.biorxiv.org/content/10.6...

Poster of the EM course in Naples with marine samples. The Electron Microscopy Hands-On Course: sample preparation and imaging of marine environmental samples arises from a very strong and active collaboration between the Stazione Zoologica Anton Dohrn and the EMBL in Heidelberg.
The aim of the course is to provide a theoretical and practical training on electron microscopy starting from the basics to the preparation of samples with high pressure freezing and image acquisition using TEM and SEM.

Two nerve nets are formed in Hydra vulgaris: the endodermal (cyan) and the ectodermal (purple) net. (B) Intraepithelial neurons are randomly scattered between the epithelial cells of the two germ layers. (C) Two types of connections have been found between Hydra’s neurons. (D) Endodermal neurons are in physical touch with each other by forming neural handshakes by digiform endings, which get intertwined. (E) In other places, clusters of vesicles of different types can be released to mediate volume transmission between neurons and between neurons and other cells.

How do neural circuits generate the walking rhythm?

Using connectome simulations, @sarahpugly.bsky.social found a minimal central pattern generator (CPG) that produces oscillations in leg motor neurons. Same circuit motif for each πŸͺ° leg.

For a decade, my white whale as a neuroscientist has been working to convince public+private funders to "go big" on post-mortem human tissue analysis, so we can define circuit disruptions in disease and just maybe link them with molecular drivers. This remains as tough a sell today as 10 years ago.
