Structure and function of acoustic neurons in the thoracic ventral nerve cord ofLocusta migratoria (Acrididae)

  1. 1.

    Individual acoustic neurons were investigated by a combined recording and staining technique (CoS). Recordings were done with CoCl2 filled glass-microelectrodes; structural identification of the fibres was achieved by precipitating the Co2+ with (NH4)2S.

  2. 2.

    The fibres of acoustic receptor neurons in the metathoracic ganglion have terminal branches only in the acoustic neuropiles. Fibres of high- and low frequency receptors were found electrophysiologically, which also differ in structure.

  3. 3.

    The thoracic low frequency neurons are interneurons of complex structure; they are limited to the thoracic ventral nerve cord.

  4. 4.

    The response patterns of acoustic neurons ascending to the supraoesophageal ganglion (B, K, C, I, and D neurons) are essentially generated in the frontal acoustic neuropiles of the metathoracic ganglion. Most of these neurons are connected with non-acoustic neuronal systems by their axon branches.
