Fluoroacoustic Multipipette Electrodes (FLAME)

Description:

Current limitations in optical imaging depth and cellular identification limit high resolution in vivo recording of different regions throughout the brain. Light delivery probes are often used for deep brain illumination to acquire spatiotemporal neuronal activity. However, these probes are still unable to perform recordings of cellular activity with high temporal resolution, primarily due to their material properties.
 
Researchers at Arizona State University have developed a novel tool which incorporates light with acoustics to navigate to specific cells types at unprecedented depths and resolutions. This platform tool, the fluoroacoustic multipipette electrode (FLAME), enables scalable and automated deep brain neuronal targeting. It shows spatiotemporal activity patterns within the neurocircuitry to facilitate precise modulation and high-resolution imaging and recording of cells deep within the living brain.
 
FLAME provides a valid and reliable foundation to target select cells deep in the brain, modulate neuronal activity, and record electrical signals from multiple neurons within a single circuit to enable transformational discoveries in neuroscience.
