Training Cognitive Control in Older Adults with the Space Fortress Game: The Role of Training <br />Instructions and Basic Motor Ability

open access: yesFrontiers in Aging Neuroscience, 2010
This study examined if and how cognitively-healthy older adults can learn to play a complex computer-based action game called the Space Fortress (SF) as a function of training instructions (Standard vs. Emphasis Change (EC); e.g.

Brain Functional Connectivity is Different during VoluntaryConcentric and Eccentric Muscle Contraction

open access: yesFrontiers in Physiology, 2016
Previous studies report greater activation in the cortical motor network in controlling eccentric contraction (EC) than concentric contraction (CC) of human skeletal muscles despite lower activation level of the muscle associated with EC.

Online visual feedback during error-free channel trials leads to active unlearning of movement dynamics: evidence for adaptation to trajectory prediction errors.

open access: yesFrontiers in Human Neuroscience, 2016
Prolonged exposure to movement perturbations leads to creation of motor memories which decay towards previous states when the perturbations are removed.

Brain Microvascular Endothelial Cell-Derived Exosomes Protect Neurons from Ischemia–Reperfusion Injury in Mice

open access: yesPharmaceuticals, 2022
Stroke often results in neurological and neuropsychiatric sequela. Exosomes derived from brain endothelial cells (EC-Exo) protect neurons from hypoxic injury.

Effects of antecedent footshock and current intensity on ECS-produced motor seizures in rats [PDF]

open access: yesPhysiological Psychology, 1973
The effects of antecedent footshock (FS) on ECS-produced motor seizures were examined. In two experiments, antecedent FS was shown to inhibit the tonic extension phase of the motor seizure without affecting a corresponding reduction in the duration of post-ECS coma.

Sex differences in the influence of body mass index on anatomical architecture of brain networks. [PDF]

open access: yes, 2017
Background/objectivesThe brain has a central role in regulating ingestive behavior in obesity. Analogous to addiction behaviors, an imbalance in the processing of rewarding and salient stimuli results in maladaptive eating behaviors that override ...

Basic Class Materials and Laboratory Projects with DC Motors in an Introductory Undergraduate ECE Class for Non-Majors [PDF]

open access: yes2011 ASEE Annual Conference & Exposition Proceedings, 2020
Basic class materials and laboratory projects with DC motors in an introductory undergraduate ECE class for non-majorsMost electrical and computer engineering departments in the United States and abroad typicallyoffer a fundamental one or two-semester course in ECE for non-major students.

Hox Genes Regulate Muscle Founder Cell Pattern Autonomously and Regulate Morphogenesis Through Motor Neurons [PDF]

open access: yes, 2010
The differentiation of myoblasts to form functional muscle fibers is a consequence of interactions between the mesoderm and ectoderm. The authors examine the role of segment identity in directing these interactions by studying the role of Hox genes in ...

Resting-state functional magnetic resonance imaging of the subthalamic microlesion and stimulation effects in Parkinson's disease: Indications of a principal role of the brainstem

open access: yesNeuroImage: Clinical, 2015
During implantation of deep-brain stimulation (DBS) electrodes in the target structure, neurosurgeons and neurologists commonly observe a “microlesion effect” (MLE), which occurs well before initiating subthalamic DBS.

Progressive impairment of CaV1.1 function in the skeletal muscle of mice expressing a mutant type 1 Cu/Zn superoxide dismutase (G93A) linked to amyotrophic lateral sclerosis [PDF]

open access: yes, 2016
Background: Amyotrophic lateral sclerosis (ALS) is an adult-onset neurodegenerative disorder that is typically fatal within 3–5 years of diagnosis. While motoneuron death is the defining characteristic of ALS, the events that underlie its pathology are
