Overview

"Willow reduced per-channel cost by an order of magnitude compared to what had been commercially available." –Ed Boyden

Many aspects of neuroscience are data-starved because of technological bottlenecks. LeafLabs is overcoming this challenge by eliminating these bottlenecks at every stage of the pipeline. Willow is the first product developed from the collaboration of LeafLabs and SNG: the 1024-channel data node is designed to be modular, one-tenth the cost per channel of existing systems, and scalable. The data node contains an FPGA that processes 1024 channels of electrophysiological data by communicating concurrently with as many as 32 industry-standard neural amplifier chips. The raw, wide-band data is written directly to a storage drive by the FPGA, while simultaneously being forwarded to a computer for real-time feedback and monitoring by the user.

The Challenge

The brain is tremendously complex, and uncovering its secrets requires huge amounts of high-resolution data. No adequate commercial systems existed to record from the probe’s 1,000 channels.

Performance Results

The Synthetic Neurobiology Group was able to record high channel count experiments. SNG now uses the Willow system routinely to record high channel count experiments. Through this collaboration, LeafLabs has become a critical resource for Dr. Boyden and his research in developing new tools for neuroscience.
