Reflex response to airway occlusion in human inspiratory muscles when recruited for breathing and posture.

J Appl Physiol (1985) 2018 Dec 6. Epub 2018 Dec 6.

Neuroscience Research Australia and The University of New South Wales, Sydney, Australia.

Briefly occluding the airway during inspiration produces a short-latency reflex inhibition in human inspiratory muscles. This occlusion reflex seems specific to respiratory muscles; however, it is not known whether the reflex inhibition has a uniform effect across a motoneurone pool when a muscle is recruited concurrently for breathing and posture. In this study, participants were seated and breathed through a mouthpiece that occluded inspiratory airflow for 250 ms at a volume threshold of 0. Read More

The Roles of Dietary Glutamate in the Intestine.

Authors:
Daniel Tomé

Ann Nutr Metab 2018 3;73 Suppl 5:15-20. Epub 2018 Dec 3.

Glutamate (Glu), either as one of the amino acids of protein or in free form, constitutes up to 8-10% of amino acid content in the human diet, with an intake of about 10-20 g/day in adults. In the intestine, postprandial luminal Glu concentrations can be of the order of mM and result in a high intra-mucosal Glu concentration. Glu absorbed from the intestinal lumen is for a large part metabolized by enterocytes in various pathways, including the production of energy to support intestinal motility and functions. Read More

Functional Head Impulse Testing Might Be Useful for Assessing Vestibular Compensation After Unilateral Vestibular Loss.

Front Neurol 2018 19;9:979. Epub 2018 Nov 19.

Department of Clinical Sciences Lund, Faculty of Medicine, Skåne University Hospital, Lund University, Lund, Sweden.

Loss of the vestibulo-ocular reflex (VOR) affects visual acuity during head movements. Previous studies have shown that compensatory eye-saccades improve visual acuity and that the timing of the saccade is important. Most of the tests involved in testing VOR are made with passive head movement, that do not necessarily reflect the activities of daily living and thus not being proportionate to symptoms and distresses of the patients.

Young spontaneously hypertensive rats (SHRs) display prodromal schizophrenia-like behavioral abnormalities.

Prog Neuropsychopharmacol Biol Psychiatry 2018 Nov 28;90:169-176. Epub 2018 Nov 28.

Department of Pharmacology, Universidade Federal de São Paulo, São Paulo, Brazil; National Institute for Translational Medicine (INCT-TM, CNPq/FAPESP/CAPES), Ribeirão Preto, Brazil. Electronic address:

The Spontaneously Hypertensive Rat (SHR) strain has been suggested as an animal model of schizophrenia, considering that adult SHRs display behavioral abnormalities that mimic the cognitive, psychotic and negative symptoms of the disease and are characteristic of its animal models. SHRs display: (I) deficits in fear conditioning and latent inhibition (modeling cognitive impairments), (II) deficit in prepulse inhibition of startle reflex (reflecting a deficit in sensorimotor gating, and associated with psychotic symptoms), (III) diminished social behavior (modeling negative symptoms) and (IV) hyperlocomotion (modeling the hyperactivity of the dopaminergic mesolimbic system/ psychotic symptoms). These behavioral abnormalities are reversed specifically by the administration of antipsychotic drugs. Read More

This paper revisits the taxonomy of the neurophysiological consequences of a persistent impairment of motor command execution in the classic environment of sensorimotor restriction and muscle hypo-mobilization in short position. Around each joint, the syndrome involves 2 disorders, muscular and neurologic. The muscular disorder is promoted by muscle hypo-mobilization in short position in the context of paresis, in the hours and days after paresis onset: this genetically mediated, evolving myopathy, is called spastic myopathy.

Age-Related Differences in the Cutaneous Vascular Response to Exogenous Angiotensin II.

Am J Physiol Heart Circ Physiol 2018 Nov 30. Epub 2018 Nov 30.

Emory University.

Angiotensin II (AngII) is locally produced in human skin and contributes to the reflex vasoconstriction (VC) response in aged but not young skin. We hypothesized that the exogenous AngII-mediated VC response will be greater in older adults and will be affected by inhibition of adrenoreceptor or angiotensin II type II receptor (ATR) pathways. Three microdialysis (MD) fibers were placed in the forearm skin of 11 young (26 ± 3 years) and 11 older (68 ± 4 years) individuals for perfusion of 1) Ringer's (control), 2) adrenoreceptor blockade with yohimbine + propranolol, and 3) ATR inhibition with PD-123319.

Acquisition, Maintenance, and Therapeutic Use of a Simple Motor Skill.

Curr Opin Behav Sci 2018 Apr 3;20:138-144. Epub 2018 Feb 3.

National Center for Adaptive Neurotechnologies, Wadsworth Center, New York State Department of Health, P.O. Box 22002, Albany, NY 12201, USA.

Operant conditioning of the spinal stretch reflex (SSR) or its electrical analog, the H-reflex, is a valuable experimental paradigm for studying the acquisition and maintenance of a simple motor skill. The CNS substrate of this skill consists of brain and spinal cord plasticity that operates as a hierarchy-the learning experience induces plasticity in the brain that guides and maintains plasticity in the spinal cord. This is apparent in the two components of the skill acquisition: task-dependent adaptation, reflecting brain plasticity; and long-term change, reflecting gradual development of spinal plasticity.
