Secret Weapons: Defenses of Insects, Spiders, Scorpions, and Other Many-Legged Creatures
This book is dominantly about chemical defences of terrestrial arthropods, though other types of defences (camouflage, catapulting, sticky traps) are also mentioned. Chapters are short, and typically… Expand
Receptive fields of motor neurons underlying local tactile reflexes in the locust
The receptive fields of motor neurons to a hind leg were mapped by recording intracellularly from their cell bodies or from the muscle fibers they innervate while stimulating mechanoreceptors on the… Expand
Octopamine mediated relaxation of maintained and catch tension in locust skeletal muscle.
It is suggested that a primary function of DUMETi is to change the response of the muscle from one that favours maintenance of posture to one that Favours rapid changes in joint position or force, such as might occur during locomotion. Expand
Anatomy and physiology of spiking local and intersegmental interneurons in the median neuroblast lineage of the grasshopper
The range of anatomical and physiological properties in the adult progeny of an identified neuroblast was investigated and it is established that the small DUM neurons are spiking interneurons, expressing passively conducted action potentials in the cell body. Expand
Spiking local interneurons as primary integrators of mechanosensory information in the locust.
It is concluded that the spiking local interneurons are major elements in the primary integration of inputs from external receptors on the hindlegs, and are involved in at least two types of pathways for local interactions: 1) sensory neuron-spiking local Interneuron-motor neuron, and 2). Expand
Engrailed Negatively Regulates the Expression of Cell Adhesion Molecules Connectin and Neuroglian in Embryonic Drosophila Nervous System
It is argued that differential Engrailed expression is crucial in determining the pattern of expression of cell adhesion molecules and thus constitutes an important determinant of neuronal shape and perhaps connectivity. Expand
Neurons of the median neuroblast lineage of the grasshopper: A population study of the efferent DUM neurons

A group of lineally related neurons in the grasshopper was studied to determine the number of efferent neuron in the group and their morphological types, and 19 efferent neurons were identified, named according to the lateral nerves containing their axons. Expand
Midline lineages in grasshopper produce neuronal siblings with asymmetric expression of Engrailed.
It is shown that each ganglion mother cell from the median neuroblast produces two neurons of asymmetric type: one isEngrailed positive (of interneuronal fate); and one is Engrailed negative (of efferent fate). Expand
Organization of receptive fields of spiking local interneurons in the locust with inputs from hair afferents.
The receptive fields of spiking local interneurons in the locust were defined by making intracellular recordings from them while stimulating mechanoreceptors on the surface of a hindleg. All the… Expand
