At present, this data set contains data from 4,207 neurons. About 4,000 more will appear later in the same format as supplemental data sets. However, some neurons were incompletely studied and their data may need to be set aside depending upon the analysis.
This data set is an appending from several studies (see references below) in which the protocol was essentially the same for the included data. The user should check for statistically significant differences among the data from these studies.
These data have been prepared as rectangular ASCII tables to provide the most generality for import into a variety of data analysis systems. The data are organized in BLOCKs, each containing a subset of variables. Each neuron has been arbitrarily assigned a unique number UN# (not in the order of data collection). This number specifies to which neuron (table row) the data in the BLOCK belongs. The first link provides a list of symbol definitions and variable names with the encoding for the group variables.
Many of the BLOCKs contain zeros to fill out the table where there was no data. The users will have to make the required transformation to {null} for the data processing system they use. [a zero for DPTH in BLOCK 01 is real, in this case, -1 is used for {null}]. BLOCKs 06-15 have been appended to each other in sequence because they are relatively small. The users will have to split them apart with a text editor as needed.
The data files are in HTML with the data bracketed as TEXT rather than as an FTP site so that the user can actually look at the data before deciding to store them. Use your browser's 'File/ Save As' and assign a 'file name' to store a local copy. Then use a text editor to remove the HTML code at the beginning and end of the file as well as the column labels.
In experiments 21, 22, and 23 (see Symbols, Variables and Encoding below), the same number of tracks were run in each animal at each of sites 1, 2 and 3 (Fig. 1). The relative number of neurons responding at these sites can be determined from this subset.
