In work with Professor Fragouli’s group and UCLA neurophysicist Professor Mehta, we have been investigating neuronal signaling in the hippocampus and the medial entorhinal cortex (MEC). In initial work, we used tools from machine learning and information information theory to understand aspects of neuronal signaling, including how to decode the stimuli from the neuronal signals. We are focusing more recently on the MEC to understand potentially superposition of positional, directional and speed information through grid-like patterns in coding of neuronal firing.
