JointPST Tool                  

Many electrophysiology experiments have a repeated stimulus paradigm in which a stimulus is turned on, then turned off, then there is a rest period, then the stimulus is turned on and off again. Researchers often want to align the spike records by the StimOn time to see if there are particular patterns of spiking aligned to the stimulus.

This tool uses the analysis code from MULAB to compute the Joint Peristimulus Time Histogram (JPSTH). This analysis allows a user to investigate the correlation structure between the responses of two different neurons to the same stimulus. As with the PST, it is designed to be used with data collected using a repeated stimulus. Details of the analysis are explained at the Mulab website: http://mulab.physiol.upenn.edu/analysis.html
