Stujenske Lab Studying emotional control circuits

Techniques & Tools

Our group actively develops and disseminates software with applications to neuroscience research. We primarily develop tools using Matlab. Here we provide links to open source tools that we use, developed in the lab and elsewhere.

Techniques

Two photon calcium imaging
Two photon calcium imaging Imaging activity in genetically-identified and spatially-localized neurons in vivo

This is a major technique used by the lab to understand coding of information in individual cells and neural populations across time.

Electrophysiology
Electrophysiology In vivo extracellular recordings

This is another major technique for tracking activity in neural populations. We use micro-LED silicon probes and CMOS-based high density probes, among other approaches.

Anatomy
Anatomy Understanding cell types and connections

Our lab uses immunostaining, brain clearing, and viral approaches to understand cells and circuits.

Optogenetics
Optogenetics Manipulating cells and circuits

Our lab uses optogenetics to activate or silence cells and circuits, while monitoring the effects using electrophysiology. See “modeling for optogenetics” below.

Fiber photometry
Fiber photometry Tracking genetically defined populations

Our lab uses fiber photometry to explore the activity of genetically-defined populations and projections.

Behavior and physiology
Behavior and physiology Tracking behavioral and physiological metrics of internal state response simultaneously

Our lab has a method to non-invasively track multiple behavioral and somatic parameters that response to environmental changes.

Stujenske Lab Resources

Modeling for Optogenetics
Modeling for Optogenetics Predict light and heat spread from optic fibers

This is a github package containing the code for Monte Carlo and heat diffusion simulations as published in Stujenske et al., 2014, Cell Reports.

Tiff Read & Write
Tiff Read & Write Suite of tools for fast reading and writing of uncompressed tiffs in Matlab.

Includes TiffViewer, which can load a HUGE tiff stack in a matter of SECONDS.

ReadOIR
ReadOIR Read Olympus .oir files in Matlab and/or convert to tiff.

This is a fork of another repo. Used with Tiff Read & Write repo, can convert .oir files to tiffs quickly.
