Generation of specific behaviors in a locust by local release into neuropil of the natural neuromodulator octopamine.
The natural insect neuromodulator octopamine (OCT) was released iontophoretically into regions of neuropil in locust metathoracic ganglia. A narrowly-defined site was found on one side of theExpand

The neuronal basis of behavior in Tritonia. I. Functional organization of the central nervous system.
An account is presented of the brain (paired cerebral, pleural, and pedal ganglia) of the nudibranch mollusc Tritonia diomedia. The major efferent nerve fibers are related to their nerve cell bodiesExpand

The neuronal basis of behavior in Tritonia. 3. Neuronal mechanism of a fixed action pattern.
We have investigated the roles played by numerous identified brain cells in initiating and controlling the coordinated sequence of movements of an instinctive escape-swimming sequence in an intactExpand

The Mechanism of Rapid Running in the Ghost Crab, Ocypode Ceratophthalma
1. Ocypode ceratophthalma has a maximum speed of 2.1 m/sec when running on a measured track with a base of hard-packed sand. Speed increases linearly with the width of the carapace up to a certainExpand

Potassium Ions and Insect Nerve Muscle
1. The ionic composition of the blood of insects, unlike that of vertebrates and most other invertebrates, shows a wide range of values, especially in regard to the physiologically important ions ofExpand

Neural mechanisms underlying behavior in the locust Schistocerca gregaria. I. Physiology of identified motorneurons in the metathoracic ganglion.
A preparation of the desert locust, Schistocera gregaria, has been developed, in which it was possible to work with identified neurons while still allowing some behavior. A total of 26 motorneuronsExpand
