Genetically Encoded Voltage Indicators

Genetically encoded indicators of voltage offer the promise of less invasive monitoring of identified neuronal activity. Several fluorescent indicators have been developed but the use in in vivo experiments remains minimal. I will discuss efforts by our laboratory to produce indicators that perform better in in vivo experiments in mammalian cortex. This involves novel fluorescent protein discovery and engineering of indicator molecules as well as in vivo application in mammalian brain.

Optimal Control of an Epileptic Neural Population Model

In this talk, I will present the model and a formulation of the seizure abatement goal expressed as an optimal control problem. I will show several results including a realistic, noise-driven simulation where the control is applied as needed in a moving window. Finally, I will present results from our ongoing work that investigates spatially heterogenous and patient specific models and stimuli.

Characterizing and manipulating multisensory perceptual networks

Sensory brain areas traditionally thought to be dedicated to a single modality can exhibit multimodal responses. These responses may be evidence for crossmodal recruitment (i.e., sensory processing for inputs in a non-primary modality); however, the direct contribution of this activity to perception is unclear...

High-Resolution Brain Machine Interfaces using Flexible Silicon Electronics

Current implantable brain devices for clinical and research applications require that each electrode is individually wired to a separate electronic system. Establishing a high-resolution interface over broad regions of the brain is infeasible under this constraint, as an electrode array with thousands of passive contacts would require thousands of wires to be individually connected. To overcome this limitation...

Universal laws and architectures: theory and lessons from hearts, bugs, brains, nets, grids, flows and zombies

The objectives of this talk are to 1) accessibly introduce a new theory of network architecture relevant to biology, medicine and technology, while minimizing math details, and 2) illustrate the key ideas with familiar examples from neuroscience, including live demos using audience brains...

Bioelectronics: The Push Towards New Medicines

The functions and organ systems of our body are, to a significant extent, controlled by electrical signals that travel along the nerves. Bioelectronic medicines will aim to control biological processes and treat disease by modulating these electrical impulses...

Electronic, Optical and Magnetic Materials for Neural Interrogation

The mammalian nervous system is often compared to an electrical circuit, and its dynamics and function are governed by ionic currents across the membranes of neurons. Many neurological disorders are characterized by inhibited/amplified neural activity in a particular region of the nervous system (e.g., depression) or lack of communication...
