Myofascial Pain.

Semin Neurol 2018 Dec 6;38(6):640-643. Epub 2018 Dec 6.

Department of Neurology, Boston University School of Medicine, Boston, Massachusetts.

Myofascial pain syndromes arise from acute and chronic musculoskeletal pain and often have a referred neuropathic component. It affects more than three quarters of the world's population and is one of the most important and overlooked causes of disability. The origins of pain are thought to reside anywhere between the motor end plate and the fibrous outer covering of the muscle, with involvement of microvasculature and neurotransmitters at the cellular level.

Freely chosen and instructed actions are terminated by different neural mechanisms revealed by kinematics-informed EEG.

Neuroimage 2018 Dec 3. Epub 2018 Dec 3.

Cognitive Neuroscience, Institute of Neuroscience and Medicine (INM-3), Research Centre Jülich, 52425, Jülich, Germany; Department of Neurology, University Hospital Cologne, 50924, Cologne, Germany.

Neurophysiological accounts of human volition are dominated by debates on the origin of voluntary choices but the neural consequences that follow such choices remain poorly understood. For instance, could one predict whether or not an action was chosen voluntarily based only on how that action is motorically executed? We investigated this possibility by integrating scalp electroencephalograms and index-finger accelerometer recordings acquired while people chose between pressing a left or right button either freely or as instructed by a visual cue. Even though freely selected and instructed actions were executed with equal vigor, the timing of the movement to release the button was comparatively delayed for freely selected actions. Read More

Possible cold-adaptation for the fungal kinesin in compensation for thermal stability acquired by single amino acid substitution.

J Biochem 2018 Dec 5. Epub 2018 Dec 5.

Department of Biosciences, College of Humanities and Sciences, Nihon University, 3-25-40 Sakurajosui, Setagaya-ku, Tokyo, Japan.

The amino acid sequence of the motor domain of AnKinA, kinesin-1 from Aspergillus nidulans, growing optimally at 37°C, was compared with that of SbKin1, kinesin-1 from the snow mold Sclerotinia borealis. For cold-adaptation, some enzymes are thought to exhibit augmented protein structure flexibility, acquired most effectively by substituting a glycine residue for another amino acid residue. By the comparison described above, two glycine residues proximal to tightly-bound ADP were identified in the SbKin1 motor domain, of which the corresponding residues of AnKinA were non-glycine ones (P60 and S323).

Two ancient neuropeptides, PACAP and AVP, modulate motivated behavior at synapses in the extrahypothalamic brain: a study in contrast.

Cell Tissue Res 2018 Dec 5. Epub 2018 Dec 5.

Section on Molecular Neuroscience, Laboratory of Cellular and Molecular Regulation, NIMH-IRP, Building 49, Room 5A-32, 9000 Rockville Pike, Bethesda, MD, USA.

We examine evolutionary aspects of two primordial neuropeptides, arginine vasopressin (AVP) and pituitary adenylate cyclase-activating polypeptide (PACAP); the distribution of AVP and PACAP and their receptors in mammals; AVP and PACAP release patterns relevant to their roles in neuroendocrine control in brain and periphery; and finally the intricate interlocking of homeostatic and allostatic regulation created by extrahypothalamic AVP and PACAP projections to brain circuit nodes important in controlling appetitive, avoidance and aggressive motor responses. A cardinal feature of peptide neurotransmission important in regulatory control of organismic responses and emphasized in this review, is that neuropeptides are released from large dense-core vesicles docked not only within axonal varicosities and dendrites but also at presynaptic nerve terminal sites, along with small clear synaptic vesicles, at active zones. Peptide transmitter nerve terminals, from hypothalamic and other projections, are distributed widely to multiple brain areas important in integrative control of behavior. Read More

Conditional Haploinsufficiency of β-Catenin Aggravates Neuronal Damage in a Paraquat-Based Mouse Model of Parkinson Disease.

Mol Neurobiol 2018 Dec 6. Epub 2018 Dec 6.

Department of Pathology, Case Western Reserve University, 2103 Cornell Road, Cleveland, OH, 44106, USA.

The canonical Wnt pathway is critical for both the development and adulthood survival and homeostatic maintenance of the midbrain dopaminergic (DA) neurons. Expanding evidence has demonstrated that genetic factors associated with familial Parkinson disease (PD) deregulate this important pathway, suggesting that a disturbed canonical Wnt pathway is likely involved in PD pathogenesis; yet, the specific role of this pathway in sporadic PD remains unclear. In this study, we aimed to determine the effects of specific inhibition of the canonical pathway by hemizygous knockout of β-catenin, the obligatory component of the canonical Wnt pathway, on paraquat (PQ)-induced DA neuronal degeneration in the substantia nigra in vivo.

Improved Neural Control of Movements Manifests in Expertise-Related Differences in Force Output and Brain Network Dynamics.

Front Physiol 2018 21;9:1540. Epub 2018 Nov 21.

Institute of Sports Medicine, Paderborn University, Paderborn, Germany.

It is well-established that expertise developed through continuous and deliberate practice has the potential to delay age-related decline in fine motor skills. However, less is known about the underlying mechanisms, that is, whether expertise leads to a higher performance level changing the initial status from which age-related decline starts or if expertise-related changes result in qualitatively different motor output and neural processing providing a resource of compensation for age-related changes. Thus, as a first step, this study aims at a better understanding of expertise-related changes in fine motor control with respect to force output and respective electrophysiological correlates.

Disruption of Multiple Distinctive Neural Networks Associated With Impulse Control Disorder in Parkinson's Disease.

Front Hum Neurosci 2018 21;12:462. Epub 2018 Nov 21.

Department of Psychiatry, Faculty of Medicine, Masaryk University and University Hospital Brno, Brno, Czechia.

The phenomenon of impulsivity in Parkinson's disease appears as an arduous side effect of dopaminergic therapy with potentially detrimental consequences for the life of the patients. Although conceptualized as a result of non-physiologic chronic dopaminergic stimulation, recent advances speculate on combined disruption of other networks as well. In the search for neuroanatomical correlates of this multifaceted disturbance, this study employs two distinct, well-defined tasks of close association to motor inhibition and decision-making impulsivity, Go/No Go and Delay discounting.

Mutations in the gene encoding superoxide dismutase 1 (SOD1) lead to misfolding and aggregation of SOD1 and cause familial amyotrophic lateral sclerosis (FALS). However, the implications of wild-type SOD1 misfolding in sporadic forms of ALS (SALS) remain unclear. By screening human memory B cells from a large cohort of healthy elderly subjects, we generated a recombinant human monoclonal antibody (α-miSOD1) that selectively bound to misfolded SOD1, but not to physiological SOD1 dimers.

Myosins are molecular motors that use a conserved ATPase cycle to generate force. We investigated two mutations in the converter domain of myosin V (R712G and F750L) to examine how altering specific structural transitions in the motor ATPase cycle can impair myosin mechanochemistry. The corresponding mutations in the human beta-cardiac myosin gene are associated with hypertrophic and dilated cardiomyopathy, respectively. Read More

An Oculus Rift Assessment of Dynamic Balance by Head Mobility in a Virtual Park Scene: A Pilot Study.

Motor Control 2018 Dec 5:1-16. Epub 2018 Dec 5.

1 New York University.

Postural sway does not differentiate between balance disorders. Head kinematics within a salient, immersive environment could potentially help identifying movement patterns that are unique to vestibular dysfunction. We describe a virtual park scene, where participants are asked to avoid a virtual ball approaching their head, to target dynamic balance and quantify head movement strategy. Read More
