We are investigating image-guided transcranial application of focused ultrasound (tFUS) to neuromodulation. We have developed a unique paradigm for tFUS utilizing our dual-mode ultrasound array (DMUA) prototypes. DMUAs are capable of subtherapeutic or therapeutic of tFUS while providing real-time monitoring and localization of its interactions with brain tissue. Our DMUA prototypes have been shown to detect and localize both mechanical and thermal tFUS-tissue interactions with brain tissues in a rat model in vivo.

My current research focuses on the development and integration of 7T MRI and high-field neuroimaging data into deep brain stimulation (DBS) surgical navigation in particular and brain surgery in general. We are developing new structural/anatomical imaging  which are combined with post processing image analysis schemes for the creation of a 3-dimensional anatomical  model of the brain. This 3D model created by the 7T images allows us to literally ‘see’ the individual shape, size and orientation of the brain target area for DBS therapy.

My group is primarily interested in developing and refining neural interface technologies to improve the quality of life for people with movement disorders. Deep brain stimulation (DBS) is one such technology, which over the past twenty years has helped numerous patients with Parkinson’s disease, dystonia, and essential tremor reclaim control over their motor function. The therapy involves placing small electrodes in regions of the brain that exhibit pathological activity, which contributes to the movement disorder, and then stimulating those regions with continuous pulses of electricity. My lab focuses on understanding how the brain responds and adapts to such stimulation-based therapies from a combination of computational and experimental perspectives. The knowledge gained from these studies in turn provides us with a framework to develop, evaluate, and translate new approaches for improving patient outcome.

Suhasa Kodandaramaiah's research group is focused on engineering neurotechnologies that help better understand how computations that occur in the brain drive behavior. A critical challenge for modern neuroscience is to study neuronal computations across multiple spatial and temporal scales. Traditionally, technologies used to observe activities at one level do not scale to the next level without loss of signal fidelity or information. HIs laboratory is combining expertise in robotics, precision engineering, optics and microfabrication for engineering technologies that seek to bridge these experimental scales.

We are using neuromodulation techniques to understand the role of the neurohormone orexin in energy balance. Our laboratory first developed the idea that orexin drives spontaneous physical activity (SPA) and non-exercise activity thermogenesis (NEAT); that it interacts with other neurotransmitters and brain sites in a network fashion; and that it has relevance to obesity: higher orexin signaling is associated with greater SPA and NEAT, the lean state and obesity resistance. Recently we have shown that orexin stimulation - either by direct receptor stimulation with orexin A injections in rats, or by DREADD [Designer Receptors Exclusively Activated by Designer Drugs] stimulation of orexin neurons in mice, prevents diet-induced adiposity and weight gain. This, coupled with our use of optogenetics to understand effects of acute simulation and inhibition of orexin neurons, and the recent development of the CAV2-Cre virus, which transfers Cre recombinase retrogradely between neurons, allows us to begin the study of orexin thermogenic pathways relevant to obesity.

Neuronal networks, diversity, and specificity of function are important to both physiological processes and neurological disorders, including epilepsy.  My laboratory seeks to improve our understanding of how cells interact within a network, how networks interact with each other, and the physiological roles of neuronal populations.  In this regard, key questions remain in epilepsy research, including what are the principal networks, conditions, and cell types involved in initiating, sustaining, propagating, terminating, and potentially suppressing, seizures.  By improving our understanding of these, we improve the prospects of someday reaching the goal of no seizures, no side effects, for all epilepsy patients.  My lab uses rodent models of neurological disorders, including temporal lobe epilepsy, and techniques including electrophysiology, optogenetics, immunocytochemistry, transgenic animals, and behavioral experiments to address these fundamental questions.

The goal of my research is to utilize novel DBS paradigms based on the generation of rotating fields by amplitude and frequency modulated pulses, for efficient low energy modulation of thalamic – cortical pathways. The general objective is to optimize DBS pulse shapes to generate excitation of selective neuronal populations. The work on animal models is critical for the translation of more efficient and safer DBS strategies to humans. Development of novel efficient schemes which allow for flexible and selective excitability of cell’s and axonal populations is critical. The detection of network level activity leaded to a breakthrough development of resting state functional MRI (rsfMRI) methodologies. Our preliminary studies demonstrate that strikingly different functional connectivity outcomes can be robustly measured by fMRI in rest and activated conditions upon different DBS paradigms, thus substantiating the rationale for this project.

In the Center for Applied and Translational Sensory Science (CATSS) lab, we are working on the development and refinement of sensory aids for sensory loss. Most of Dr. Nelson’s work is focused on auditory perception and device evaluation. Specifically, we believe that auditory sensory aids (hearing aids and cochlear implants) have progressed to the point where speech intelligibility is conveyed quite successfully, at least for understanding in quiet environments. We believe the next stage is improving the sound quality and ease of listening for users of these sensory aids.  Improving these abilities would ensure that the central auditory system has acclimated to the new inputs, and is processing them as natural acoustic information.  Visual and vestibular implants are in earlier stages of development, but show promise to improve sensory input to the brain to improve quality of life for millions of Americans.

Brain disorders and mental illness represent a tremendous social and economic burden, with few effective treatments. The goal of our research is to identify the causes of brain conditions, and develop interventions to restore healthy function using synaptic plasticity and neuromodulation. We study the striatum, and important brain region for both simple and complex movements and cognitive functions. We examine the function of neural circuits formed by striatal synapses that connect specific sources and targets. Our multidisciplinary approach includes quantitative analysis of gene expression; genetic and molecular manipulations of neural circuits; measurement of synaptic function and plasticity using electrophysiology; and optogenetic stimulation of circuits in brain slices and behaving animals. Our current research focuses on autism spectrum disorders and drug addiction - two brain conditions that affect overlapping elements of striatal circuitry.

I came late to neuromodulation, having been trained as a neuro-oncologist with research interests in quantitative neuroimaging and computational anatomy.  With the advent of deep brain stimulation (DBS) for the treatment of movement disorders in the 1990's I recognized an opportunity to transfer my computer skills and computational interests to programming the implanted pulse generators used for DBS.  My clinical and research interests in DBS focus on the poorly-understood high-dimensional space created by the multiple parameters — active contacts, applied voltage, pulse width, constant current, and stimulation frequency — that are routinely selected to modulate DBS in individual patients.

Our group invents and applies protein engineering technologies to study how cells sense, integrate and exchange information, how pathologic changes in these processes relate to health and disease, and provide insights into new therapies. We are developing novel optogenetic reagents that allow us to systematically perturb specific ion channels and signaling receptors in a time- and amplitude-variant manner. We combine these molecular reagents into an experimental framework in which all families of ion channels and receptors can be independently controlled, and their contribution to diverse cellular signal transduction circuits investigated.

We study the therapeutic effect and efficacy of vagal nerve stimulation (VNS) therapy in experimental in-vivo animal models, aiming to assess the effects of VNS therapy on the functional and electrophysiological properties of the heart. We continuously record in-vivo ECG and blood pressure to characterize the effect of VNS on heart rate, blood pressure and arrythmias. We also perform ex-vivo optical mapping experiments in the isolated whole heart that  allow us to study complex spatio-temporal organization of electrical activity encountered in the heart during normal and abnormal rhythms, and investigate the electrophysiological properties induced by VNS in both healthy and diseased hearts.
