Cortex-Wide to Single-Cell Resolution
Optogenetics and Calcium Imaging:
Cortical Circuit Mapping
Overview

Optogenetics and calcium imaging have advanced the field of neuroscience by providing precise methods for manipulating and imaging neural activity in vivo. In order to map large-scale cortical to single-cell circuits, it is essential to have the ability to perform large-scale targeted optogenetics and calcium imaging in vivo, as depicted by the methodology below.
