Analyzing intracranial electrophysiology data with xarray

Over the last few years, it has been exciting to see the xarray project evolve, add new functionality, and mature. This post is an attempt at giving xarray another visit to see how it could integrate into electrophysiology workflows.

It is common in neuroscience to ask individuals to perform a task over and over again. You record the activity in the brain each time they perform the task (called an “epoch” or a “trial”). Time is recorded relative to some onset when the task begins. That is t==0. The result is usually a matrix of epochs x channejupyls x time. You can do a lot of stuff with this data, but our task in this paper is to detect changes in neural activity at trial onset (t==0).
