Core Services

Our Electrophysiology Core focuses on electrophysiology and muscle physiology.

This Core expands the capabilities of neuroscience research on campus by making available specialized expertise, equipment and assistance to support electrophysiological analyses of signal transduction and synaptic function in cultured cells, tissue slices and zebrafish embryos.

Microelectrodes record intracellular activity of individual neurons in rat hypothalamic tissue slices.

Available services:

  • Technical expertise, equipment and consultation for conducting electrophysiological studies
  • Extracellular or patch clamp recordings to screen for alterations in synaptic transmission, such as measurement of EPSP or EPSC or alteration in LTP or LTD, in cerebellar, hippocampal, hypothalamic and spinal cord slices
  • Electrophysiological studies of voltage- and ligand-channels in isolated or cultured neurons

Please see our Terms of Service and User Fee Structure for specifics regarding use of this core.
