About aa-2

Information about the data.


This data set contains about 500 single-unit recordings from different audio areas in zebra finches.  The specific areas recorded from include: Caudal Mesopallium (CM); Primary Forebrain (from subareas L1, L2a, L2b, L3 and L);  Nucleus Ovoidalis (OV); and Mesencephalicus lateral dorsalis (MLd).  In most of the experiments, recordings were collected from two brain regions simultaneously.  For each experiment multiple sound stimuli were used.  In most cases each stimulus was repeated about 10 times.  The experiments for much of the data are summarized in the following paper:

Sound representation methods for spectro-temporal receptive field estimation.  Journal of Computational Neuroscience. 2006 Aug;21(1):5-20 (10.1007/s10827-006-7059-4).  Patrick Gill, Junli Zhang, Sarah M. N. Woolley, Thane Fremouw and Frédéric E. Theunissen

Information about stimuli and responses from OV can be found in this paper:

Role of the Zebra Finch Auditory Thalamus in Generating Complex Representations for Natural Sounds. Journal of Neurophysiology.  2010 Aug;104(2):784-98. (10.​1152/​jn.​00128.​201). Noopur Amin, Patrick Gill, Frederic E Theunissen

Format of the data.

Responses of neurons are stored as text files with each row specifying the times of individual spikes to a particular trial of a stimulus.  Stimuli are stored as audio wav files.  Details of the dtat formats are describe in file crcns-aa2-README.txt.  The total size of the data set is about 180 MB uncompressed.

Conditions for using the data.

The data took years to collect by the experimenters.  Instructions for crediting and consulting the experimenters is given in the README.txt file for the data set.
