Tutorial: Circuits and Technologies for Cell and Brain Interfacing

Cell and brain interfacing has gained a lot of interest in recent years. Thanks to advancements in technology scaling, current state-of-the-art systems are able to record the electrical activity down to single neuron resolution from several hundreds of recording sites at the same time. This is a critical tool for the neuroscientist to help understand how our brain operates. In recent years, stimulation has also gained a lot of interest. Neural stimulation serves many potential applications like restoring bodily functions for disabled people, suppressing pain, brain-computer-interfaces and Parkinson?s disease. This tutorial will focus on the circuit techniques and technologies to enable such high-density neural recording and stimulation. It will go from high-level system design aspects, to processing/technology aspects (electrodes) and will end with specific circuit design techniques.
