title: An apparatus for studying electroretinographic responses under conditions of space flight.
abstract: This project has developed so as to include the total range of electroretinographic responses under conditions of space flight. We built two special containers which made stratospheric balloon flights. The second prototype carries the following specifications: Immobilisation of two frogs; Light stimulation by flashes; Special corneal electrodes; Amplification and recording system. There is almost no tissue damage after prolonged observation (several days) of the animals and the electroretinographic responses do not show any significant changes. Such an apparatus could be used as the basis for an assembly to be incorporated into Spacelab.
