1/ Mapping synaptic connectivity between individual neurons is extremely laborious. We developed BRISC, a new method that makes it possible to map inputs onto 100s of neurons in the same animal in a matter of weeks! Led by Alex Becalick and @antblot.bsky.social. 🧵

Many of us use 2p scopes to image 3D volumes of brain. But then we analyze the data plane by plane, resulting in duplicated neurons, missed neurons, and low s/n. Let's go 3D!

When I first joined here I remember there being a lot of posts about how the 'culture' of bluesky was to block liberally and starve the trolls.

I just hope people are still doing that!

Everyone who is able should be doing this. And growing as much of their own food as they can, and saving seed

But individuals can only do so much, and millions don't have the means to stockpile or grow

The government should be making appropriate plans NOW

A #SciencePerspective by @zalaly.bsky.social and @erictopol.bsky.social identifies key issues that need to be prioritized in the study of #LongCovid.

Learn more on #LongCovidAwarenessDay: scim.ag/3XKbds3
Many forms of Long Covid: Long Covid is a multisystemic disease with sequelae that affect almost all organ systems. Various putative mechanisms that underlie these sequelae are not mutually exclusive and may explain the myriad health effects seen in Long Covid. Therapeutics that target these pathways, such as antivirals, anti-inflammatory agents, microbiome restoration, and anticoagulant drugs, may ameliorate symptoms.

Are you using GCaMP8 or are planning to switch from GCaMP6? Then check out this new preprint from our lab! www.biorxiv.org/content/10.1...

- Calcium imaging
- GCaMP8 vs. GCaMP6
- Spike inference
- Imaging + ephys ground truth

With F. Helmchen, K. Svoboda, M. Rozsa & X. Fang.
Three images with figure excerpts from the paper, highlighting 1) single-spike detection analysis, 2) autocalibration analysis, and 3) non-linearity of calcium-to-fluorescence transfer functions and their effect on the reporting of complex spiking events.

Scientists need to face the reality that this is not some temporary funding crisis while a bumbling administration sorts out their priorities.

This is an intentional assault on academia by accelerationist extremists who wish to break society. Fascism must be met in the streets.
