Using Digital Spatial Profiling for Transcriptomic Analysis of Neuronal Subpopulations
The Scientist Creative Services Team in collaboration with Advanced Cell Diagnostics | 1 min read
Kit Fuhrman and Anushka Dikshit present how to obtain whole transcriptome data from spatially mapped neuron populations.
This is DishBrain, an in vitro system that combines human brain cells with artificial intelligence technology, which researchers at Australian biotech Cortical Labs recently trained to play the classic 1972 Atari video game Pong. Fluorescent markers show axons in green, neuron bodies in purple, dendrites in red, and all other cells in blue. Where multiple markers are present, colors are merged and typically appear as yellow or pink. Posted: October 12, 2022
