This review summarizes the contribution to neurobiology achieved through the use of
invertebrate preparations in the second half of the 20th century. This fascinating period was …

Invertebrate escape reflexes have long been favoured preparations for investigating
neuronal substrates of behaviour. The large size of many of their component neurones make …

This review was constructed to show how the connectome has evolved in motor command
systems from simple command elements to complex systems of neurons utilizing parallel …

Students of the compound eye deserve to be pleased with the scope and depth of their
knowledge about the diversity of physiological optics and receptor structure. The same may …

Command fibers located in the circumesophageal connectives which modify scaphognathite
and heart rhythms have been mapped and characterized in the crab, Cancer magister …

Several discrete postures have been generated by electrical stimulation at frequencies of 20–
75 Hz of command interneurons within the circumoesophageal connectives of the crayfish …

The motor effects evoked by stimulation of each of eight command fibres in the
circumoesophageal commissures of the crayfish are described. The fibres obtained …

Extrinsic systems were shown to control the excitability of the neurones which mediate tail-
flip escape in the crayfish. Restraint suppresses the escape mediated by giant fibres and …

Command interneurons from the circumoesophageal connectives of crayfish which are
capable of evoking various cyclical, phasic behavioural outputs are described. By pooling …

For the crayfish, properties of visually reacting intemeurone types in the optic nerve are
described on the basis of single-unit analysis. Sustaining fibres show:(a)'surround'inhibition …
