Areas of interest: Neural circuits, vocal learning, time-frequency analysis, brain-machine interfaces
The Gardner lab studies the mechanisms of temporal sequence perception and production, focussing on vocal learning in songbirds.
The song circuit produces stereotyped structure over a range of time-scales from milliseconds to tens of seconds. We ask how complex songs are assembled from elementary neural units. What are the relationships between patterns of neural activity on different time-scales?
The lab also studies information processing in auditory cortex, examining how auditory signals are transformed as they move from low to high level sensory areas. How are memories for temporal patterns formed?
To address these questions, we develop minimally invasive electrodes that provide stable neural recordings in behaving animals. We also develop high-resolution signal processing algorithms for auditory and neural time-series.
