To study the effects of stimulus duration on neural responses, it is essential to be able to modify stimulus timing paradigms rapidly. A four-channel programmable timing device (PTD) has been designed to provide flexible and accurate data-acquisition timing protocols, PTD outputs are used to control data-acquisition and stimulus-generation peripherals. Four attributes of the timing protocol are programmable: trial duration, stimulus duration, stimulus onset delay, and a number of trials. The use of the PTD has allowed for a more detailed description of dorsal cochlear nucleus unit-response properties.
