Research Topics
- Development of unsupervised robotic hardware for high throughput animal training in tactile decision-making tasks.
- Dissecting neural circuits controlling somatosensory topographic map reorganization and tactile decision-making using spatially restricted, temporally gated neural (in)activation techniques.
- Electrical and optical reconstruction of the cortical column to understand the local circuits subserving somatosensory map reorganization.
- Understanding the neural codes underlying somatosensory map reorganization by large-scale 3D electrophysiological recordings in awake behaving animals.
Research Overview
Topographic representations in the primary sensory cortices are believed to be the neural basis of sensory perception. These representations are continuously altered during learning and after sensory organ loss. Despite their role in sensory information processing, the mechanisms by which they are modified is still unknown. The major goal of our lab is to describe the neural circuits and the synaptic mechanisms responsible for the development and maintenance of the sensory representations using in vivo and in vitro electrophysiological recordings, imaging, computerized behavioral trainings and molecular biological methods.Contact Information
