Spectral and ocellar inputs to honeybee motion-sensitive descending neurons
… wavelength processing in motion-sensitive descending neurons, which are on the optomotor response pathway, to reveal the neural contributions from other spectral receptor types. In this study, intracellular recording techniques were utilised. The stimuli consisted of a wide-field LED (light …

Glutamate regulates neurite outgrowth of descending neurons in culture from larval lamprey
In spinal cord-transected larval lamprey, descending brain neurons, most of which are reticulospinal (RS) neurons, regenerate their axons across a transection site and contribute to behavioral recovery. In the present study, DiI-labeled descending brain neurons in larval lamprey were dissociated …

Descending premotor target tracking systems in flying insects
… pairs of bilaterally symmetric Target Selective Descending Neurons (TSDNs) relay visual information about small moving objects from the brain to the thoracic motor centres. These neurons encode the movement of small moving objects across the dorsal fovea region of the eye which is fixated on prey …

Descending Control of Limb Movements in Drosophila melanogaster
… but not limited to walking), the contribution of descending inputs to the generation of movements is difficult to study. Here we take advantage of the relatively small number of descending neurons (DNs) in the Drosophila melanogaster model system. We first characterize the number and distribution …

The Logic of Innately Aversive Olfactory Pathways
… the brain, and discovered a previously unknown descending neuron that senses geosmin, and is required for the innate aversion to geosmin exhibited during egg-laying. Connectomics analysis showed that this cell converges with other descending neurons in the ventral nerve cord of the fly that are …

Intrinsic Neural Control of Propulsion, Storage and Slow Transit in the Large Intestine.
… repetitive firing of ascending excitatory and descending inhibitory neuronal pathways lie in the CM, in close opposition to the myenteric plexus. Mechanosensitive ion channels present on the sensory elements are likely to be responsible for the transduction of the circumferential stretch.In the …
