Dr. Schulz's lab studies diseases at the cellular and clinical level that affect cognition and behavior. The lab is especially interested in the mechanisms underlying normal cognition and neurodegenerative disorders.
The basic science research in the lab focuses on the cellular mechanisms underlying cognition and behavior, and how they are altered by neurologic disease. We use electrophysiological recording techniques, such as patch-clamp recordings and extracellular recordings, to record from a single neuron or groups of neurons. Several projects focus on the normal mechanisms underlying long-term potentiation (LTP), long-term depression (LTD), and decremental forms of plasticity. One set of projects focuses on explicating different forms of LTD and their transcriptional regulation. In another project, we are investigating the cellular mechanisms underlying decremental plasticity, including using mutant mice to understand the underlying mechanisms. Another project examines dendritic channels that are altered with LTP- we have also found that inhibition of these channels may enhance neuronal excitation after stroke and contribute to neuronal death. In another project, we record from single or small groups of synapses to demonstrate the addition of silent synapses to the development of LTP. Finally, the lab is interested in mutant mouse models of neurodegenerative disorders that can be used to investigate mechanisms that contribute to neuronal loss.
The clinical research in the lab focuses on investigating neurodegenerative disorders at several levels. The lab is interested in how to better diagnose and differentiate between neurodegenerative disorders. We are interested in how to treat them, especially the disorders for which no treatments currently exist. Neuroepidemiology is used to investigate general medical illnesses that alter the probability or speed of progression of neurodegenerative disorders – these types of studies give us insights into the mechanisms involved in neurodegeneration. The lab uses clinical studies to understand the prevalence of various behavioral changes (like aggression) and how to treat them. The lab is interested in how cognitive functions, like semantic memory, are altered in diseases like epilepsy and by epilepsy surgery. Functional imaging is used to investigate human interactions, their underlying anatomy, and how they are altered in disease. Finally, we are using genetics to understand the genes for which mutations produce neurodegenerative disease and are especially interested in amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD).
