Abstract: The human brain is composed of billions of cells that communicate through chemical and electrical signals. LLNL microelectrodes can interface directly with the brain to allow us to monitor and manipulate the dynamics of these brain signals. LLNL microelectrodes are flexible and microfabricated in dense arrays that allow them to collect large amounts of information over long periods of time in the body. We will go over how these arrays are microfabricated and their diagnostic and therapeutic applications.

Abstract: The human brain contains approximately 86 billion neurons, and 100 trillion connections between those neurons. Despite our inability to image each neuron and determine their exact connective patterns, several approaches for noninvasive imaging of the living brain have been developed and utilized to great benefit. In this talk, we will explore the immense landscape of the human brain and quantify the brain in terms of data flow. Then we will describe engineering applications of recorded electrophysiological data. We will also explore methods for analyzing such data to determine the pattern of signals that arise during various activities and mood states.

Abstract: Cancer becomes highly dangerous when it spreads from its original site to a different vital organ. These secondary tumors called metastases are what kill most patients. Despite hundreds of years of research, it is not understood why, where, and how cancer spreads to organs like the brain. A major limitation in our current knowledge is how we study this process; most metastasis research is performed in mice. At LLNL, we are building systems to watch metastasis happen. Using 3D printing technology paired with advanced computer modeling, we create functional human brain blood vessels to monitor how cancer cells spread to the brain and form a tumor. This talk will describe how we bring together cancer biology, 3D printing and material science, to understand and hopefully prevent metastases in the future.
