Real-time, motion compensation in Scanbox

Our colleague Tobias Rose was recently asking about Scanbox’s ability to stabilize the motion of images and signals from regions-of-intrest (ROIs) in real-time.  The goal of such processing is to be able to do experiments in closed-loop, and do very quick analyses on the neuronal responses, such as computing tuning curves on the fly. Below is a…

Sorting calcium imaging signals

Originally posted on xcorr: comp neuro:
Calcium imaging can record from several dozens of neurons at once. Analyzing this raw data is expensive, so one typically wants to define regions of interest corresponding to cell bodies and work with the average calcium signal within. Dario has a post on defining polygonal ROIs using the mean fluorescence…
