Information about the data.


This data set contains single unit electrophysiological recordings of neurons in Nucleus Interface in juvenile male zebra finches (Taeniopygia gutatta). Recordings were taken while birds were singing (n = 89 single units, including 29 HVC-projectors), and also while they were listening to a tutor (n = 103 single units, including 29 HVC-projectors). In addition to neural recordings, we have included simultaneously recorded audio recordings. The results are reported in:

Mackevicius EL, Happ MTL, Fee MS. An avian cortical circuit for chunking tutor song syllables into simple vocal-motor units. In revision at Nature Communications 2020.

The methods that were used to collect this data are described in detail in the following protocol:
