[A direct current amplifier for measuring eye saccades].

For testing saccadic eye movements three methods are used today: the coil-, the infrared- and the electrode-method. All of these techniques are endowed with advantages and disadvantages. The electrode-method that uses the dipole-character of the eye needs a DC-amplifier with small noise and drift error. The amplifier described here complies with these requirements. It has been used for a long time and disapproves the general opinion that the coil- and the infrared-method are the more expensive but in all cases the better methods.
