About aa-4
Summary.
This data set contains extra-cellular electrophysiological recordings from 6 urethane anesthetized adult zebra finches (Taeniopygia guttata), 4 males and 2 females. At each electrophysiological recording site a set of sounds was presented to the subject. This set was made from 10 ripple noise stimuli of 2 sec., and 20 songs of zebra finches and the vocalizations from the repertoire of 10 individuals. The maximum number of stimuli that could be selected in that procedure was 171. The average number of stimuli played for each single unit was 144. Ten trials were acquired for each stimulus with a few exceptions. Sounds were broadcasted in a random order.
Neural responses were recorded using the signal of two (5 subjects) or one (1 subject) electrode arrays. When two electrode arrays were used, they were placed each in one hemisphere, targeting the following avian auditory cortical regions: Field L (including the thalamo recipient L2, the primary auditory regions L1 and L3), caudolateral and caudomedial mesopallium (CLM and CMM) and caudomedial nidopallium (NCM). Data contains spike times for 914 single auditory units from the 1401 auditory spike-sorted units of all our recordings. Additional details on these experiments can be found in:

Format of the data.
The data of spike arrival times and stimuli played are saved for each single-unit as an h5 file. A matlab notebook along with the functions it is calling is provided as a first exploration tool of the data. Details are given in the document at the bottom of this page.
