Impedance Spectroscopy of Newt Tails

We use impedance spectroscopy to characterize the electrical properties of newt tail. The newt model has attracted recent interest because the regeneration of newt tail and limbs may provide insights into tissue engineering for mammals. Impedance spectroscopy could provide a convenient means to monitor the progress of regeneration while various controlling stimuli are applied. In this initial phase of our research we compare the impedance spectra of healthy and necrotic tail tissue and identify a potentially confusing artifact in the spectra due to interneedle capacitance.
