The range of anatomical and physiological properties in the adult progeny of an identified neuroblast was investigated. Some 80–90 adult neurons constitute the dorsal unpaired median (DUM) group of the grasshopper metathoracic ganglion. Within the group are efferent, octopaminergic neurons with large cell bodies and overshooting action potentials. Our objective was to determine the properties of the neurons with small cell bodies that make up the majority of the clone, some 60–70 neurons, about… Expand
Neurons of the median neuroblast lineage of the grasshopper: A population study of the efferent DUM neurons
TLDR
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
Interneurons with inhibitory effects on stridulation in grasshoppers exhibit GABA-like immunoreactivity
Three identified descending interneurons (SOG-1, -2, -3) of the suboesophageal ganglion are described that have inhibitory effects on stridulatory movements in the grasshoppers Chorthippus mollis andExpand
Engrailed protein is expressed in interneurons but not motor neurons of the dorsal unpaired median group in the adult grasshopper
TLDR
The differential expression of En in the embryo and its continued expression in the adult nervous system suggest a role in the development and maintenance of neuronal phenotype. Expand
Anatomy and physiology of neurons composing the commissural ring nerve of the cricket, Acheta domesticus.
TLDR
The primary function of the RN of the cricket Acheta domesticus is to serve as a peripheral nerve commissure and that its role as a neurohemal organ is negligible. Expand
Cellular configuration of single octopamine neurons in Drosophila
TLDR
This work maps the segmental location and developmental origins of individual octopamine neurons in the Drosophila subesophageal ganglion and demonstrates that two sets of unpaired median neurons exhibit the same projection patterns in the brain. Expand

TLDR
This report analyzes the development of the CNS midline in the grasshopper embryo, focusing on the median neuroblast (MNB) cluster, which contains the majority of midline neurons and finds that this neuroblast is actually a multipotent progenitor cell. Expand
Synaptic activation of efferent neuromodulatory neurones in the locust Schistocerca gregaria.
TLDR
The persistence of common synaptic potentials in neurones of the three subsets in isolated ganglia indicates that they are derived from neurones within the metathoracic ganglion, lending further support to the idea that there is a subdivision of action amongst this population of DUM neurones.

Origin and clonal relationship of common inhibitory motoneurons CI1 and CI3 in the locust CNS.
In the primordial thoracic ganglia of locust embryos, the bromodeoxyuridine (BrdU) technique for labelling proliferating cells and their progeny was combined with intracellular dye injection toExpand
Distribution of GABA‐like immunoreactive neurons in insects suggests lineage homology
TLDR
There is a two‐ to threefold increase in numbers of thoracic neurons between the flightless Thysanura and the most advanced orders of insects, and it is found that only selected lineages have significantly contributed to this increase in neuronal numbers. Expand
Auditory DUM neurons in a bush-cricket: inhibited inhibitors
TLDR
In bush-crickets, the largest population of local auditory neurons in the prothoracic processing centre are dorsal unpaired median (DUM) neurons, which are suggested to be inhibitory using γ-aminobutyric acid (GABA) as transmitter. Expand

The morphology of local non‐spiking interneurones in the metathoracic ganglion of the locust
The morphology is described of a number of non‐spiking interneurones in the metathoracic ganglion of the locust that control motor neurones innervating muscles in the coxa and femur of a hind leg.Expand
Heterogeneous properties of segmentally homologous interneurons in the ventral nerve cord of locusts
TLDR
It is shown that the G, B1, and B2 neurons are segmental homologues in that they arise from equivalent lineages during embryogenesis in the T2, T3, and A1 segments, respectively. Expand
Physiological characteristics and reflex activation of DUM (octopaminergic) neurons of locust metathoracic ganglion.
TLDR
It is suggested that the DUM neurons of the metathoracic ganglion of the locust Schistocerca gregaria and the grasshopper Romalea microptera will be found to have many functions serving a general role comparable to that achieved by the release of adrenaline in vertebrates. Expand
Activation of DUM cell interneurons by ventral giant interneurons in the cockroach, Periplaneta americana.
TLDR
These data, taken along with the known association of DUM cells with the neuromodulatory substance octopamine, suggest that the DUM interneurons may act to modulate central synapses. Expand

TLDR
The hypothesis that transmitter determination is at least in part regulated by cell lineage in the grasshopper embryo is supported and that some clonally related neurons appear to share a common transmitter determination by virtue of their common lineage is suggested. Expand
Motor neurons of grasshopper metathoracic ganglion occur in stereotypic anatomical groups
TLDR
Similarities between the morphology of the adult groups reported here and the descriptions by others of embryonic and larval nervous systems suggest to us that the motor neurons of each group are the progeny of a single neuroblast. Expand
Spiking local interneurons as primary integrators of mechanosensory information in the locust.
TLDR
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
Structure and distribution of dorsal unpaired median (DUM) neurones in the abdominal nerve cord of male and female locusts

This paper aims to fill the gap by systematically describing the number and morphology of DUM neurones in each of the abdominal ganglia of male and female locusts by backfilled the lateral nerves of each abdominal ganglion to reveal the position of the somata of D UM neurones. Expand
Graded synaptic transmission between local interneurones and motor neurones in the metathoracic ganglion of the locust.

A number of physiological tests indicate that the graded effects upon motor neurones are mediated by chemical synaptic transmission. Expand

TLDR
It appears unlikely that the DUM neurons examined play a major central role within the metathoracic ganglion, but a novel structure, with the appearance of a presynaptic density but which was not associated with synaptic vesicles, was found in certain regions of the neurons. Expand
