Extracellular

Extracellular

Extracellular research measures and characterizes the electrical properties of cells and tissues, particularly neurons and neuronal tissue. Measurements are usually performed either in the extracellular fluid near the cell of interest, or non-invasively. These measurements can be divided into three main groups, which include single/multiple unit recordings, whole nerve recordings, and extracellular field potentials. Epithelial voltage clamping recording can also be classified under extracellular recordings.

Easily acquire and analyze extracellular potentials from nerves and brain slices, and seamlessly assess conscious neural activity, extracellular spikes, and extracelllular field potentials, by using a combination of the PowerLab 35 series and our extracellular neural amplifiers.

Noise Elimination

This is a common issue in electrophysiology as you are dealing with very small signals as well as high impedance and capacitance of electrodes. All of ADInstruments hardware is optimized with high-quality noise specifications, but it is always good to have a few other tricks up your sleeve to help in your setup. 

  1. Ensure all electronic equipment used in recording setup is plugged into the same wall socket by using a fused multibox.
  2. Ensure all shielding is connected to one grounding point or grounding bar. This will eliminate the risk of a grounding loop when different grounds are at slightly different potentials causing currents to flow in the shielding introducing noise.
  3. To identify the source of noise, strip back to the bare essentials, like the amplifier and acquisition and then systematically switch on additional equipment.
  4. Always try to eliminate the source of noise first, but if this isn’t possible then mask with shielding.
  5. Try and keep lead wires as short as possible and not looped. If they are long, try braiding them to prevent magnetically induced currents.
  6. Even fluid filled tubing for perfusions can act as antennas. If this is the case, shield with tin foil and connect to the metal grounding bar.
