The Distribution of the Olivo-Cochlear Bundle and its Possible Role in Frequency/Intensity Coding

  • Phyllis E. Stopp
Conference paper


There are two methods by which sensory systems signal changes in the stimulus intensity — by an increase in the pulse rate within a fibre and by an increase in the number of fibres activated. There may also be a change from low threshold to high threshold channels. In general, as we proceed along a sensory pathway towards the cortex, the relationship between stimulus strength and discharge rate becomes less strong (Hilali and Whitfield, 1953; Katsuki et al., 1959) and may cease to be monotonic; thus the number and identity of the fibres becomes relatively more important.
