Morphological characteristics of motor neurons do not determine their relative susceptibility to degeneration in a mouse model of severe spinal muscular atrophy. [PDF]

open access: yesPLoS ONE, 2012
Spinal muscular atrophy (SMA) is a leading genetic cause of infant mortality, resulting primarily from the degeneration and loss of lower motor neurons.

Motor neurons and the generation of spinal motor neurons diversity [PDF]

open access: yesFrontiers in Cellular Neuroscience, 2014
Motor neurons (MNs) are neuronal cells located in the central nervous system (CNS) controlling a variety of downstream targets. This function infers the existence of MN subtypes matching the identity of the targets they innervate.

Motor neurons are dispensable for the assembly of a sensorimotor circuit for gaze stabilization [PDF]

open access: yeseLife
Sensorimotor reflex circuits engage distinct neuronal subtypes, defined by precise connectivity, to transform sensation into compensatory behavior. Whether and how motor neuron populations specify the subtype fate and/or sensory connectivity of their pre-

Motor cortex analogue neurons in songbirds utilize Kv3 channels to generate ultranarrow spikes

open access: yeseLife, 2023
Complex motor skills in vertebrates require specialized upper motor neurons with precise action potential (AP) firing. To examine how diverse populations of upper motor neurons subserve distinct functions and the specific repertoire of ion channels ...

Motor Neuron Diseases

open access: yesDeckerMed Neurology, 2022
The motor neuron diseases (MNDs) are a family of diseases commonly categorized by their propensity to affect upper or lower motor neurons and by their mode of inheritance. The chapter provides some content on infectious MNDs caused by viral infections affecting the motor neurons in the anterior horn of the spinal cord. However, the chapter devotes most

A size principle for recruitment of Drosophila leg motor neurons

open access: yeseLife, 2020
To move the body, the brain must precisely coordinate patterns of activity among diverse populations of motor neurons. Here, we use in vivo calcium imaging, electrophysiology, and behavior to understand how genetically-identified motor neurons control ...

Motor neurons in the escape response circuit of white shrimp (Litopenaeus setiferus) [PDF]

open access: yesPeerJ, 2015
Many decapod crustaceans perform escape tailflips with a neural circuit involving giant interneurons, a specialized fast flexor motor giant (MoG) neuron, populations of larger, less specialized fast flexor motor neurons, and fast extensor motor neurons ...

Onecut-dependent Nkx6.2 transcription factor expression is required for proper formation and activity of spinal locomotor circuits. [PDF]

open access: yes, 2020
In the developing spinal cord, Onecut transcription factors control the diversification of motor neurons into distinct neuronal subsets by ensuring the maintenance of Isl1 expression during differentiation.

Calcium imaging of CPG-evoked activity in efferent neurons of the stick insect. [PDF]

open access: yesPLoS ONE, 2018
The stick insect is a well-established experimental animal to study the neural basis of walking. Here, we introduce a preparation that allows combining calcium imaging in efferent neurons with electrophysiological recordings of motor neuron activity in ...

Aging alters mechanisms underlying voluntary movements in spinal motor neurons of mice, primates, and humans

open access: yesJCI Insight, 2023
Spinal motor neurons have been implicated in the loss of motor function that occurs with advancing age. However, the cellular and molecular mechanisms that impair the function of these neurons during aging remain unknown. Here, we show that motor neurons
