Psychophysical Theory of Human Pitch Processing

We study the mechanisms of fundamental frequency (pitch) adaptation of songbird and human vocalizations. Adaptation can be induced as a response to distortions of pitch feedback.

Analysis of birdsong development and automated clustering of song syllables

During early development, young songbirds such as the Zebra Finch learn acoustically complex but stereotyped sequential behaviors which are termed "songs". Furthermore, zebra finches learn only one song in their lifetime, making the problem of developmental song analysis tractable.

Reinforcement learning of human vocal behavior

We study reinforcement learning of fundamental frequency (pitch) in songbirds and humans. When birds receive aversive reinforcement for low-pitch syllables they successfully learn to increase the syllables’ pitch.

The role of successful and unsuccessful trials during motor learning

Reinforcement (‘good dog’, ‘bad dog’) is one of the main strategies to train animals and humans. We have used this strategy extensively in the lab to train songbirds to change their song and study the neural correlates of vocal and motor learning.

Neuronal controllers for cognitive robots

In our group “Neuromorphic Cognitive Systems", we develop neuronal architectures that allow robots to generate behavior (e.g. navigate in an environment, avoid obstacles, pursue targets), to form memories (e.g. build a map), and learn.

Real-time feedback-controlled delivery of neuromodulators for non-invasive high-resolution modulation of brain

We are employing MRI guided focused ultrasound based delivery of neuromodulators to control activity of specific brain micro circuits and subsequent cognitive behavior, which has both fundamental and medical applications.

Neural underpinnings of auditory observational learning in Zebra Finches

Learning by observation is an important decision making strategy. We examined this in songbirds by pairing zebra finches and training one finch (demonstrator) to discriminate song syllables while the other (observer) observes this behavior. We show that observer finches acquire this behavior faster.
