Measuring the Song Circuit We use miniature, motorized electrode
drives to record activity from single cells in targeted brain
regions of the singing bird. These recordings allow us to
understand how the song is represented in different parts of the
song circuit and how this neural representation evolves as a
function of learning. We also combine electrical recordings with
manipulations of nearby circuits to shed light on how neural
responses in a given area are influenced and shaped by activity
in adjacent brain regions. Song aligned spike rasters (start and
end of song denoted by asterisk) recorded from RA during
singing, at different times during development. Each color
denotes a different cell.
