Modulation of stomatogastric rhythmsWolfgang Stein
Institute of Neurobiology, Ulm University, 89069, Ulm, Germany
J Comp Physiol A Neuroethol Sens Neural Behav Physiol 195:989-1009. 2009..Future challenges include exploring the behavioral conditions under which these systems are activated and how their effects are regulated...- Gastric and pyloric motor pattern control by a modulatory projection neuron in the intact crab Cancer pagurusUlrike B S Hedrich
Department of Neurology and Epileptology, Hertie Institute for Clinical Brain Research, Tubingen, Germany
J Neurophysiol 105:1671-80. 2011..Thus modulatory projection neurons such as MCN1 can control the motor output in vivo, and they participate in the processing of exteroceptive sensory information in behaviorally relevant conditions... - Light-induced effects of a fluorescent voltage-sensitive dye on neuronal activity in the crab stomatogastric ganglionWolfgang Stein
Institute of Neurobiology, Ulm University, Ulm D 89069, Germany
J Neurosci Methods 188:290-4. 2010..It may thus also be used as a means to study the maintenance of phase relationships in rhythmic motor patterns... - Motor pattern selection by nitric oxide in the stomatogastric nervous system of the crabWolfgang Stein
Abteilung Neurobiologie, Universitat Ulm, D 89069 Ulm, Germany
Eur J Neurosci 21:2767-81. 2005..Together, our results show that ascending feedback from a motor network is important in shaping network activity and that this feedback is state-dependent and can be modulated to alter the output of the motor network... - Functional consequences of activity-dependent synaptic enhancement at a crustacean neuromuscular junctionWolfgang Stein
Abteilung Neurobiologie, Universitat Ulm, D 89069 Ulm, Germany
J Exp Biol 209:1285-300. 2006..We conclude that the augmentation of EJPs at the neuromuscular junction tunes the muscle response to support force production during rhythmic motor patterns... - Intersegmental transfer of sensory signals in the stick insect leg muscle control systemWolfgang Stein
Abteilung Neurobiologie, Universitat Ulm, D 89069 Ulm, Germany
J Neurobiol 66:1253-69. 2006.... - Regulation of motor pattern frequency by reversals in proprioceptive feedbackCarmen R Smarandache
Institute of Neurobiology, Ulm University, D 89069 Ulm, Germany
Eur J Neurosci 28:460-74. 2008..Our study thus shows that the cycle frequency of centrally generated activity patterns can be regulated by switching the sign of phasic proprioceptive feedback... - Motor pattern selection by combinatorial code of interneuronal pathwaysWolfgang Stein
Institute of Neurobiology, Ulm University, 89069 Ulm, Germany
J Comput Neurosci 25:543-61. 2008..That is, a switch between behaviors, such as standing to walking, can be brought about by altering the strengths of selected sensory integration pathways... - Frequency control of motor patterning by negative sensory feedbackJessica Ausborn
Institute of Neurobiology, Ulm University, D 89069 Ulm, Germany
J Neurosci 27:9319-28. 2007..This regulatory mechanism appears to be a general emergent property of negative feedback systems... - Differential activation of projection neurons by two sensory pathways contributes to motor pattern selectionUlrike B S Hedrich
Institute of Neurobiology, Ulm University, D 89069 Ulm, Germany
J Neurophysiol 102:2866-79. 2009..Our results thus support the hypothesis that sensory pathways activate different combinations of projection neurons to select distinct outputs from the same neuronal circuit... - Regulation of motor patterns by the central spike-initiation zone of a sensory neuronNelly Daur
Institute of Neurobiology, Ulm University, Ulm, Germany
Eur J Neurosci 30:808-22. 2009..Our results thus demonstrate that sensory neurons are not mere reporters of sensory signals. Neuromodulators can elicit non-sensory coding activity in these neurons that shapes the state of the motor system... - Single-sweep voltage-sensitive dye imaging of interacting identified neuronsWolfgang Stein
Institute of Neurobiology, Ulm University, D 89069 Ulm, Germany
J Neurosci Methods 194:224-34. 2011..We argue that imaging of neural networks with identifiable neurons with well-known connectivity, like in the STG, is crucial for the understanding of emergence of network functionality... - Simultaneous measurement of membrane potential changes in multiple pattern generating neurons using voltage sensitive dye imagingCarola Städele
Institute of Neurobiology, Ulm University, 89069 Ulm, Germany
J Neurosci Methods 203:78-88. 2012..We argue that imaging of neural networks with identifiable neurons with well-known connectivity, like in the STG, is crucial for the understanding of emergence of network functionality... - Sensory-induced modification of two motor patterns in the crab, Cancer pagurusCarmen R Smarandache
Institute of Neurobiology, Ulm University, D 89069 Ulm, Germany
J Exp Biol 210:2912-22. 2007..This work thus provides an initial framework for future studies to determine underlying common principles... - Characterization of a descending pathway: activation and effects on motor patterns in the brachyuran crustacean stomatogastric nervous systemUlrike B S Hedrich
Institute of Neurobiology, Ulm University, D 89069 Ulm, Germany
J Exp Biol 211:2624-37. 2008..The IV neurons were thus capable of synchronizing the activities of different motor circuits, which demonstrates the regulation of motor patterns by higher-order neuronal centers... - The stomatogastric nervous system as a model for studying sensorimotor interactions in real-time closed-loop conditionsNelly Daur
Institute of Neurobiology, Ulm University Ulm, Germany
Front Comput Neurosci 6:13. 2012..We report the real-time capabilities of our models, its performance and its interaction with the biological motor system... - Divergent co-transmitter actions underlie motor pattern activation by a modulatory projection neuronWolfgang Stein
Department of Neuroscience, University of Pennsylvania School of Medicine, Philadelphia, PA 19104, USA
Eur J Neurosci 26:1148-65. 2007..Thus, a modulatory projection neuron can elicit rhythmic motor activity by using distinct co-transmitters, with different time courses of action, to simultaneously influence different CPG neurons... - Actions of a histaminergic/peptidergic projection neuron on rhythmic motor patterns in the stomatogastric nervous system of the crab Cancer borealisAndrew E Christie
Department of Neuroscience, University of Pennsylvania School of Medicine, Philadelphia, Pennsylvania 19104, USA
J Comp Neurol 469:153-69. 2004..These results support the hypothesis that the histaminergic/peptidergic IV neurons are projection neurons with direct and indirect actions on the STG circuits of the crab C. borealis... - Functional recovery following manipulation of muscles and sense organs in the stick insect legUlrich Bässler
Chamissostr 16, 70193, Stuttgart, Germany
J Comp Physiol A Neuroethol Sens Neural Behav Physiol 193:1151-68. 2007..Our results thus indicate the existence of a sensory template that guides recovery. Recovery was limited to a behavioural range that occurs naturally in intact animals, though in different behavioural contexts...
