About am-2

Information about the data.


These data are population recordings from the zebra finch cortical song nucleus HVC during singing. Most animals had only one electrode, but some had two electrodes within HVC.  These data examine the development of a motor control circuit essential for vocal learning and production.  Juveniles, who sing plastic song, are compared to adults, who sing stable song.  Data were collected as described in:

Crandall, S.R., Aoki, N., and Nick, T.A. (2007) Developmental modulation of the temporal relationship between brain and behavior. The Journal of Neurophysiology. 97(1):806-816.

Format of the data.

Data from nine animals is provided (four adults and five juveniles).  The data for each animal is stored in a separate zip file.  The data includes the electrode recordings along with the simultaneous vocalizations made by the animal.  Data files are in MatLab format. MatLab scripts are provided for working with the data. Details about the data are provided in file crcns-am2-data-description.pdf.  Total size of all compressed data is about 46 Gigabytes.
