Calciumsignalextract: A Matlab Gui To Automatically Extract The Activity Of Multiple Cells From Calcium Imaging Data, Stephan Meyer Zum Alten Borgloh Jan 2015

Calciumsignalextract: A Matlab Gui To Automatically Extract The Activity Of Multiple Cells From Calcium Imaging Data, Stephan Meyer Zum Alten Borgloh

Gilbert Laboratory

A Matlab GUI that automatically segments fluorescence image stacks into ROIs based on differential morphology and fluorescence activity of the individual cells. The time course data of each ROI gets extracted and plotted. External data from behavioral experiments and sensory stimuli can be integrated to compare for task and stimulus dependent neuronal events


Estimating The Amount Of Information Conveyed By A Population Of Neurons, Marshall Crumiller Jan 2014

Estimating The Amount Of Information Conveyed By A Population Of Neurons, Marshall Crumiller

Knight Laboratory

Recent advances in electrophysiological recording technology have allowed for the collection of data from large populations of neurons simultaneously. Yet despite these advances, methods for the estimation of the amount of information conveyed by multiple neurons have been stymied by the “curse of dimensionality”–as the number of included neurons increases, so too does the dimensionality of the data necessary for such measurements, leading to an exponential and, therefore, intractible increase in the amounts of data required for valid measurements. Here we put forth a novel method for the estimation of the amount of information transmitted by the discharge of a …


Meyer Navigator: User Scanimage Functions To Show X/Y Positions Of The Stage/Objective In A Coordinate System, Stephan Meyer Zum Alten Borgloh Jan 2013

Meyer Navigator: User Scanimage Functions To Show X/Y Positions Of The Stage/Objective In A Coordinate System, Stephan Meyer Zum Alten Borgloh

Gilbert Laboratory

These Matlab functions extend Janelia Farms' ScanImage microscope control software. The functions allow the user to view, mark and track positions of the motor stage/objective in x, y, and z, which get displayed in a separate window. This helps to keep track of the stage movements, regions of interest and makes it easy to document areas imaged and map out the specimen being investigated. For detailed information about the functionality as well as installation, view the included manual file.
