How To: Pattern with two attractor points in Rhino 3D

In this Rhino 3D / Grasshopper software tutorial we expand on a previous video from the site, Rhino - Patterning Based on Point Distance with Grasshopper. The idea is to use 2 points rather than one. The logic is borrowed from Andy Payne on a 3ds Max model with wire parameters. Basically the idea is to drive the radius of the circles with the distance between the point(s). The circles then use the MIN component and a “range” factor to limit how big the circles can get as well as the area of i...

How To: Perform single cell electroporation of neurons

Single-cell electroporation (SCE) is a specialized technique allowing the delivery of DNA or other macromolecules into individual cells within intact tissue, including in vivo preparations. The distinct advantage of this technique is that experimental manipulations may be performed on individual cells while leaving the surrounding tissue unaltered, thereby distinguishing cell-autonomous effects from those resulting from global treatments. When combined with advanced in vivo imaging techniques...
