Professor of Biology and Neuroscience, on leave for the 2023–2024 academic year

The Horch lab uses the cricket model system to examine the molecular neurobiological basis of a number of areas including regeneration, behavior, and development. Mainly, the lab focuses on how the auditory system of the cricket recovers from injury. Removing one ear induces auditory interneurons to sprout new dendrites, grow abnormally across the mid-line, and form synapses with intact auditory neurons from the opposite ear. This is an elegant and robust example of neuronal plasticity, and it happens in adult crickets. The Horch lab uses echniques such as fluorescent backfills, immunohistochemistry, Q-PCR, RNA interference, behavioral assays, and confocal microscopy to understand the consequences of the loss of an ear.
