Research Overview


The Viventi Lab aims to develop flexible electronics to interface with the brain.  With high spatial and temporal bandwidth, micro-electrocorticography (micro-ECoG) provides a high-resolution interface with the brain by obtaining fine-scale structure over large areas of the cortex.  

Our goal is to make usable devices that are stable, repeatable and easy to build that we can use in-house and share with the research community at-large to answer interesting questions in nueroscience.  To do this, our work is focused on several key areas:
