In 2015 @alexnortn and I were writing the Eyewire Museum and Alex developed this pretty WebGL shader code for artistically showing pulses along neurites, but we didn't find a place for it at the time. Claude revived his old code and it looks cool!

I think SACs aren't spiking after a certain stage of development, it's more to show what kinds of fun things you can do with WebGL ^_^ I believe the pulses are actually flowing down the neurites!

fastremap 1.20.0
- Adds `shell=True` argument for point_cloud (3d support only currently). This extracts only the contour of the 3d shape instead of a dense point cloud.
Code is modified from the implementation in crackle.

Just published yesterday, the #BANC! A full central nervous system (CNS) connectome of a limbed animal enables us to trace sensory-motor arcs and understand how the CNS controls the body. rdcu.be/fncjS #neuroscience @Nature, Video by @quorumetrix, sound on! 1/18

Get up close with brain cells with the browser-based MICrONS Explorer: microns-explorer.org/
This #OpenScience data portal contains connectivity and functional imaging data including #ElectronMicroscopy based reconstructions of cortical circuitry from the mouse visual cortex.

It took endless hours in the lab and a massive effort, but we're finally here: Eyewire II is officially out!
Huge thanks to our amazing co-authors and everyone else who supported us along the way. So grateful for the hard work—it’s been a privilege pushing through this together.
Meet Eyewire II: a new connectomic resource for the mouse retina.
~1 mm² of retina at nm resolution, with synapses and circuits of ca. 100,000 neurons visual responses from the ~400 neurons shown in the video!

connected-components-3d 4.0.0
- deprecates the max_labels parameter (you shouldn't use it anyway)
- significantly faster 4-connected binary image CCL
12
connected-components-3d 3.29.0
- Faster 6-connected multilabel CCL ~5-15%
Finally started applying those cool state machine techniques (PRED) to multilabel algorithms.

zmesh 1.13.1
- Fixes bug in new opt-in marching cubes algorithm
github.com/seung-lab/zmesh
16
zmesh 1.14.0
- New "preserve_order=False" flag for mesh that allows a faster multivalued marching cubes algorithm to run but changes the order of vertices/faces so naive == checks between new and old meshes may be false.

On my little test volumes, it looks to be about 30% faster.
