Persistent inward currents in motoneuron dendrites: implications for motor output

CJ Heckman, MA Gorassini… - Muscle & Nerve: Official …, 2005 - Wiley Online Library
The dendrites of motoneurons are not, as once thought, passive conduits for synaptic inputs.
Instead they have voltage‐dependent channels that provide the capacity to generate a very …

Spinal cholinergic interneurons regulate the excitability of motoneurons during locomotion

GB Miles, R Hartley, AJ Todd… - Proceedings of the …, 2007 - National Acad Sciences
To effect movement, motoneurons must respond appropriately to motor commands. Their
responsiveness to these inputs, or excitability, is regulated by neuromodulators. Possible …

The anticonvulsant retigabine attenuates nociceptive behaviours in rat models of persistent and neuropathic pain

G Blackburn-Munro, BS Jensen - European journal of pharmacology, 2003 - Elsevier
We have tested for anti-nociceptive effects of the anticonvulsant KCNQ channel opener, N-(2-
amino-4-(4-fluorobenzylamino)-phenyl) carbamic acid ethyl ester (retigabine), in rat models …

Mechanisms underlying the early phase of spike frequency adaptation in mouse spinal motoneurones

GB Miles, Y Dai, RM Brownstone - The Journal of physiology, 2005 - Wiley Online Library
Spike frequency adaptation (SFA) is a fundamental property of repetitive firing in
motoneurones (MNs). Early SFA (occurring over several hundred milliseconds) is thought to …

Spike-rate coding and spike-time coding are affected oppositely by different adaptation mechanisms

SA Prescott, TJ Sejnowski - Journal of Neuroscience, 2008 - Soc Neuroscience
Spike-frequency adaptation causes reduced spiking during prolonged stimulation, but the
full impact of adaptation on neural coding is far more complex, especially if one takes into …

Synaptic disruption and CREB‐regulated transcription are restored by K+ channel blockers in ALS

A Catanese, S Rajkumar, D Sommer… - EMBO molecular …, 2021 - embopress.org
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease, which is still
missing effective therapeutic strategies. Although manipulation of neuronal excitability has …

Focal aggregation of voltage‐gated, Kv2. 1 subunit‐containing, potassium channels at synaptic sites in rat spinal motoneurones

EAL Muennich, REW Fyffe - The Journal of physiology, 2004 - Wiley Online Library
Delayed rectifier K+ currents are involved in the control of α‐motoneurone excitability, but
the precise spatial distribution and organization of the membrane ion channels that …

Preceding muscle activity influences motor unit discharge and rate of torque development during ballistic contractions in humans

M Van Cutsem, J Duchateau - The Journal of physiology, 2005 - Wiley Online Library
To investigate the effect of initial conditions on the modulation of motor unit discharge during
fast voluntary contractions, we compared ballistic isometric contractions of the ankle …

Voltage-sensitive ion channels in rhythmic motor systems

RM Harris-Warrick - Current opinion in neurobiology, 2002 - Elsevier
Voltage-sensitive ionic currents shape both the firing properties of neurons and their
synaptic integration within neural networks that drive rhythmic motor patterns. Persistent …
