Brain Slice Chamber 2: Interface

  • “Interface” method of slice maintenance
  • Single feed channel for perfusion solution
  • Use entire surface for multiple slices or reduced area with templates
  • Single well diamond shaped templates, other designs available upon request
  • Proportional temperature controller (PTCO3) with low noise performance used for heating

This slice recording chamber is designed to maintain isolated, living tissues in vitro in ‘interface’ mode and allow stable electrophysiological recordings to be made from the preparation. The temperature is controlled by a proportional control heating unit, the PTC03.

The chamber lower section is similar to the BSC-1 for temperature control and oxygenation. Pre-oxygenated medium enters the main body of the chamber through a feed line. This fine bore PTFE tube which spirals in the heated distilled water in the lower part of the chamber enters the upper part of the chamber. Here any bubbles in the line break and allow perfusion fluid to flow smoothly towards the slices. Acrylic templates allow the option for use of a single well or can be custom designed. Typical dead space volume for the single well is approx. 200 ul. The length of PTFE tubing carrying the perfusion solution to the well has a volume of approx. 400ul. The flow rate of the perfusion fluid is adjusted at the exit well by means of lens tissue which is used to wick solution out of the exit port.

By adjusting the over-hang the flow rate is effectively adjusted and determines the characteristics of the meniscus of fluid around the slice preparation. As with all interface preparations, the high oxygen tension is maintained by bubbling a 95% oxygen, 5% carbon dioxide gas mixture through a ceramic bubbler located in the lower heated part of the chamber. This moistened and warmed gas mixture enters the upper part of the chamber via port-holes and is then deflected by an acrylic cover across to the centrally located slice preparation. The temperature in the upper chamber is maintained by ensuring that the medium and moistened gas mixture enter at the required temperature. This is dependent on the temperature of the lower chamber body which is warmed by a heating element controlled by the Proportional Temperature Controller, PTC03. An optional monitor sensor allows the upper chamber temperature to be checked when required.
