Summary of recordings of spike trains available for analysis and guide to their context and means for their analysis

This is a data resource of recordings of spike activity from about 5000 neurons along the auditory pathway from the cochlear nuclei to the neocortex, cerebellum, and elsewhere. There is also an analysis program that averages histograms of spike activity and concurrent electromyographic (EMG) activity obtained from the orbicularis oculi (eyeblink) and levator oris (nose twitch) muscles. No search interface; distribution consists of a collection of Microsoft Office and Windows executable files. Each recording contains the response to a 70 dB click* (produced by applying a 1 ms rectangular pulse to a loudspeaker) before or after conditioning blink responses to the click as a CS. A discriminative acoustic stimulus, a 70 dB hiss DS, was also presented at a time apart from the click. There are guides to the regions from which each recording was made and to the associated behavioral states as well as a tutorial on how to use the analysis program. There is an appendix listing the data format. Sufficient indexes and examples are available here to understand the data. The data can be downloaded (voluminous) or borrowed on CD (5) from the UCLA Biomedical Library and copied.

There are guides to the regions from which each recording was made and to the associated behavioral states as well as a tutorial on how to use the analysis program. There is an appendix listing the data format. There is a second appendix (12. Appendix 2) with downloadable, self-executable data files of the complete database. Also available are copies of the original lab notebooks with depths of the recordings. WHAT THE ANALYSIS PROGRAM DOES 1. Averages four groups of specified spike or EMG files. 2. Graphs the current averages as peri-stimulus time histograms (PSTHs). (Check the ppt files.) 3. Adjusts scaling to specification. 4. Prints or copies the graphs to slides. 5. Creates super averages from specified averages or data from many units 6. Graphs, scales, prints and copies super averages 7. Batch processing as yet not ready for use 8. Provides detailed reports of all useful information contained within the current averages raw data files or general information about the super averages 9. Provides error messages concerning the analyses.
