Epilepsy Research
Networks of Language Processing
Investigator: Nitin Tandon, MD
Purpose: We will investigate the rapid computations that allow us to convert from the visual input of a string of letters to a known word with an associated sound and meaning using our established techniques for precise co-localization and analysis of a large population intracranial recordings, thus circumventing the sparse sampling problems inherent to human intracranial experiments. improve our understanding of written language systems and develop new ways to model neural computation. It will greatly enhance our understanding of dyslexia and language disorders following brain injury or degeneration, with our experimental focus on word learning directly informing neurobiological models of language.

Cell transplantation for epilepsy: A First-in-human (FIH), Multicenter, Open Label, Single Arm, Dose Escalation Study of Inhibitory Interneurons (NRTX-1001) in Drug-Resistant Unilateral Mesial Temporal Lobe Epilepsy (MTLE)
Multicenter trial (Sponsor: Neurona)
Purpose: Neurona Therapeutics is studying an investigational drug (NRTX-1001) as a possible treatment for drug-resistant Mesial Temporal Lobe Epilepsy. NRTX-1001 is a cell product that will be placed surgically into the brain area that originates seizures. UTHealth Houston will serve as a center for the trial.

Network based neuro-modulation for mesial temporal lobe epilepsy
Investigator: Nitin Tandon, MD
Purpose: Current stimulation treatment for MTLE involves the implantation of a recording/stimulation device with 2 electrodes placed bilaterally in the anterior nucleus of the thalamus (ANT), and the delivery of high-frequency stimulation to disrupt the epilepsy network. In this grant, we will implant two devices in each patient, which will give us 4 electrodes to implant in 4 different areas of the MTLE network. We will see if stimulating these different locations with low-frequency stimulation will produce greater seizure reduction.
