TLDR
There are six pairs of nerves, of which the sixth and most posterior are referred to as recurrent nerves since they join the first nerve of the ganglion in the metathorax.Abstract:
A description is given of those nerves which arise from the mesothoracic ganglion of Locusta migratoria migratorioides R. & F. There are six pairs of nerves, of which the sixth and most posterior are referred to as recurrent nerves since they join the first nerve of the ganglion in the metathorax. The median nerve is also described. The posterior median nerve of the prothoracic ganglion is noted as its branches make a connection with the branches of the first mesothoracic nerve. Wherever possible an attempt has been made to relate the observations to those of some other authors.read more

Chordotonal Organs of Insects

TL;DR: Combining the technologies of neurophysiology with those of genetics, electron microscopy, membrane biochemistry, and biophysics can elucidate the mechanisms that provide chordotonal sensilla with their different physiological properties.

Monosynaptic connexions between wing stretch receptors and flight motoneurones of the locust.
TL;DR: The connexions between stretch receptors of the wings and motoneurones innervating flight muscles have been studied anatomically and physiologically and it is expected that the stretch receptor will influence the time at which a mot oneurone will spike and hence have an effect on the amplitude of the upstroke and upon the phase relationship between spikes of motoneurs.

A Guide to the Neuroanatomy of Locust Suboesophageal and Thoracic Ganglia
N. M. Tyrer,G. E. Gregory +1 more
TL;DR: In this article, the thoracic and sub-oesophageal ganglia of locusts were examined in three species: Chortoicetes terminifera (Walker), Schistocerca gregaria (Forskal) and Locusta migratoria migratorioides (Reiche and Fairmaire).

Motor and sensory flight neurones in a locust demonstrated using cobalt chloride.
N. M. Tyrer,J. S. Altman +1 more
TL;DR: The central projections of motor and sensory neurons involved in the control of the wing beat in locusts have been analysed using cobalt chloride introduced axonally and the cobalt method offers an important advance in the analysis of insect neuropile.

Potassium Ions and Insect Nerve Muscle
TL;DR: It is predicted that the mechanical properties of the muscles of a herbivorous insect will be found to be subject to fairly marked changes if the blood potassium rises or falls to an appreciable extent.

The Motor Mechanism of the Insect Leg
TL;DR: A double motor innervation is described from an insect muscle, the two nerve fibres producing respectively a tonic contraction and a twitch, and the distribution of motor fibres to the muscles of the metathoracic leg of Periplaneta is described in detail.

TL;DR: Eight pairs of nerves emanate from each of the three thoracic ganglia of the adult American cockroach and the two nerves emanating from the first abdominal ganglion are characterized.
