Functional Diversity of Neurotrophin Actions on the Oculomotor System
(MDPI AG, 2016)
Neurotrophins play a principal role in neuronal survival and differentiation during development, but also in the maintenance of appropriate adult neuronal circuits and phenotypes. In the oculomotor system, we have demonstrated ...

Muscle Progenitors Derived from Extraocular Muscles Express Higher Levels of Neurotrophins and their Receptors than other Cranial and Limb Muscles
(MDPI, 2020)
Extraocular muscles (EOMs) show resistance to muscle dystrophies and sarcopenia. It has been recently demonstrated that they are endowed with different types of myogenic cells, all of which present an outstanding regenerative ...

Nerve Growth Factor Regulates the Firing Patterns and Synaptic Composition of Motoneurons
(Society for Neuroscience, 2010)
Target-derived neurotrophins exert powerful synaptotrophic actions in the adult brain and are involved in the regulation of different forms of synaptic plasticity. Target disconnection produces a profound synaptic stripping ...

Effects of Selective Deafferentation on the Discharge Characteristics of Medial Rectus Motoneurons
(Society for Neuroscience, 2018)
Medial rectus motoneurons receive two main pontine inputs: abducens internuclear neurons, whose axons course through the medial longitudinal fasciculus (MLF), and neurons in the lateral vestibular nucleus, whose axons ...

Neural Progenitor Cell Implants in the Lesioned Medial Longitudinal Fascicle of Adult Cats Regulate Synaptic Composition and Firing Properties of Abducens Internuclear Neurons
(Society for Neuroscience, 2014)
Transplants of neural progenitor cells (NPCs) into the injured CNS have been proposed as a powerful tool for brain repair, but, to date, few studies on the physiological response of host neurons have been reported. Therefore, ...

Sources and lesion-induced changes of VEGF expression in brainstem motoneurons
(Springer Nature, 2020-04-01)
Motoneurons of the oculomotor system show lesser vulnerability to neurodegeneration compared to other cranial motoneurons, as seen in amyotrophic lateral sclerosis (ALS). The overexpression of vascular endothelial growth ...

Palisade endings of extraocular muscles develop postnatally following different time courses
(Association for Research in Vision and Ophthalmology, 2017)
PURPOSE. To analyze in a frontal-eyed mammal (cat) the postnatal development of palisade endings in extraocular muscles (EOMs) and to compare the spatiotemporal and quantitative patterns of palisade endings among individual ...

Dual encoding of muscle tension and eye position by abducens motoneurons
(Society for Neuroscience, 2011)
Extraocular muscle tension associated with spontaneous eye movements has a pulse-slide-step profile similar to that of motoneuron firing rate. Existing models only relate motoneuron firing to eye position, velocity and ...

Complementary Actions of BDNF and Neurotrophin-3 on the Firing Patterns and Synaptic Composition of Motoneurons
(Society for Neuroscience, 2009)
Neurotrophins, as target-derived factors, are essential for neuronal survival during development, but during adulthood, their scope of actions widens to become also mediators of synaptic and morphological plasticity. Target ...
Tesis Doctoral
Regulación neurotrófica de las propiedades de disparo y de la sinaptología aferente sobre las motoneuronas axotomizadas del núcleo motor ocular externo
(2010)
La teoría trófica de las conexiones neuronales establece que durante el desarrollo embrionario los órganos diana son esenciales para la supervivencia y diferenciación de las neuronas que los inervan, rescatando a estas ...
