Sensory encoding of odor stimuli inPeriplaneta americana

Summary

  1. 1.

    Characteristic curves and reaction spectra were determined electrophysiologically for sensory cells on the antenna ofPeriplaneta americana responding to odors.

     
  2. 2.

    The cells were stimulated by odors from single pure substances and from complex foodstuffs applied from a cartridge and an ejection olfactometer.

     
  3. 3.

    All receptor cells investigated can be classified according to clearly defined reaction spectra. The spectra for seven groups of cells are described. There was no indication of so-called “generalists”, that is of single cells with individually unique reaction spectra.

     
  4. 4.

    All receptors of one type show the same graded sensitivity to the odorous substances of the spectrum defining the type.

     
  5. 5.

    The spectra of the different cell types show overlap.

     
  6. 6.

    The reaction of sensory cells of a given type appears to be quantitatively uniform. Such uniformity would not seem to permit distinction between various substances belonging to the reaction spectrum of a single type. Distinction would appear possible on the basis of different reaction ratios for different substances in the different types.
