Spaceflight-induced neuroplasticity in humans as measured by MRI: what do we know so far?

NPJ Microgravity

January 2017

Antwerp University Research Centre for Equilibrium and Aerospace (AUREA), University of Antwerp, Groenenborgerlaan 171, Antwerp, 2020 Belgium.

Space travel poses an enormous challenge on the human body; microgravity, ionizing radiation, absence of circadian rhythm, confinement and isolation are just some of the features associated with it. Obviously, all of the latter can have an impact on human physiology and even induce detrimental changes. Some organ systems have been studied thoroughly under space conditions, however, not much is known on the functional and morphological effects of spaceflight on the human central nervous system.

Spaceflight severely impacts the human body. However, little is known about how gravity and gravitational alterations affect the human brain. Here, we aimed at measuring the effects of acute exposure to gravity transitions.

Altered functional brain connectivity in patients with visually induced dizziness.

Neuroimage Clin

November 2017

Antwerp University Research Centre for Equilibrium and Aerospace (AUREA), University of Antwerp, Antwerp. Belgium; Faculty of Sciences, Department of Physics, University of Antwerp, Antwerp, Belgium.

Background: Vestibular patients occasionally report aggravation or triggering of their symptoms by visual stimuli, which is called visually induced dizziness (VID). These patients therefore experience dizziness, discomfort, disorientation and postural unsteadiness. The underlying pathophysiology of VID is still poorly understood.

The effect of spaceflight and microgravity on the human brain.

Antwerp University Research Centre for Equilibrium and Aerospace (AUREA), University of Antwerp, Antwerp, Belgium.

Microgravity, confinement, isolation, and immobilization are just some of the features astronauts have to cope with during space missions. Consequently, long-duration space travel can have detrimental effects on human physiology. Although research has focused on the cardiovascular and musculoskeletal system in particular, the exact impact of spaceflight on the human central nervous system remains to be determined.

Differential effect of visual motion adaption upon visual cortical excitability.

J Neurophysiol

March 2017

Academic Department of Neuro-Otology, Division of Brain Sciences, Charing Cross Hospital Campus, Imperial College London, London, United Kingdom.

The objectives of this study were ) to probe the effects of visual motion adaptation on early visual and V5/MT cortical excitability and ) to investigate whether changes in cortical excitability following visual motion adaptation are related to the degree of visual dependency, i.e., an overreliance on visual cues compared with vestibular or proprioceptive cues.

"SO STONED": Common Sense Approach of the Dizzy Patient.

Front Surg

June 2016

Department of Biomedical Physics, Faculty of Science, University of Antwerp, Antwerp, Belgium; Department of Speech, Language and Hearing Sciences, Faculty of Medicine and Health Sciences, Ghent University, Ghent, Belgium.

The history taking of a dizzy patient is of utmost importance in order to differentiate the possible etiologies of vertigo. The key factors that allow a first approximation of diagnosis identification are based on the time profile, symptom profile, and trigger profile of the disease. Here, the proposed mnemonic "SO STONED" comprises eight different dimensions that characterize the vertigo-related complaints of the patient and guide the clinician in his or her decision scheme.

Background: Vestibular patients occasionally report aggravation or triggering of their symptoms by visual stimuli, which is called visual vestibular mismatch (VVM). These patients therefore experience discomfort, disorientation, dizziness and postural unsteadiness.

Objective: Firstly, we aimed to get a better insight in the underlying mechanism of VVM by examining perceptual and postural symptoms.

Motion sickness and sopite syndrome associated with parabolic flights: a case report.

Int J Audiol

December 2016

a Antwerp University Research Centre for Equilibrium and Aerospace (AUREA), University of Antwerp Groenenborgerlaan, Antwerp , 171, 2020 , Belgium and.

Objective: The purpose of this paper was to provide an extensive description of a case of sopite syndrome, a manifestation of motion sickness scarcely described in the literature.

Design: The following questionnaires were used to assess sopite syndrome symptoms pre, during and post parabolic flight; Misery Scale rate, Positive and Negative Affect Scale, the Motion Sickness Assessment Questionnaire and the Epworth Sleepiness Scale.

Study Sample: Case report of a 35-year old female compared to a control group (n = 26).

Mal de debarquement syndrome: a systematic review.

J Neurol

Antwerp University Research Centre for Equilibrium and Aerospace (AUREA), University of Antwerp, Groenenborgerlaan 171, 2020, Antwerp, Belgium.

Mal de debarquement (MdD) is a subjective perception of self-motion after exposure to passive motion, in most cases sea travel, hence the name. Mal de debarquement occurs quite frequently in otherwise healthy individuals for a short period of time (several hours). However, in some people symptoms remain for a longer period of time or even persist and this is then called mal de debarquement syndrome (MdDS).

Introduction: Space motion sickness in astronauts during spaceflight causes significant discomfort, which might impede their functionality. Pharmacological treatment has been mainly restricted to promethazine. Transdermal and oral scopolamine have also been used in space; however, their use was reduced due to unpredictable effectiveness and side effects.

Cortical reorganization in an astronaut's brain after long-duration spaceflight.

Brain Struct Funct

June 2016

Antwerp University Research Centre for Equilibrium and Aerospace (AUREA), Antwerp University Hospital and University of Antwerp, Groenenborgerlaan 171, 2020, Antwerp, Belgium.

To date, hampered physiological function after exposure to microgravity has been primarily attributed to deprived peripheral neuro-sensory systems. For the first time, this study elucidates alterations in human brain function after long-duration spaceflight. More specifically, we found significant differences in resting-state functional connectivity between motor cortex and cerebellum, as well as changes within the default mode network.

Validation of centrifugation as a countermeasure for otolith deconditioning during spaceflight: preliminary data of the ESA SPIN study.

J Vestib Res

October 2013

Antwerp University Research Centre for Equilibrium and Aerospace AUREA, Department of Biomedical Physics, University of Antwerp, Antwerp, Belgium.

In the framework of further space exploration, countermeasures to combat the drawbacks of human space flights are essential. The present study focuses on the influence of microgravity on the otolith-ocular reflex and aims to test the hypothesis of artificial gravity being an adequate countermeasure for the deconditioning of the aforementioned reflex. The so-called SPIN study, commissioned by the European Space Agency, can be considered as a control experiment in the broad sense for the Neurolab mission (STS-90) during which 4 crewmembers of the space shuttle were subjected to in-flight centrifugation on the visual and vestibular investigation system (VVIS).

Introduction: Sensory conflicts in the vestibular system lead to motion sickness of which space motion sickness (SMS) is a special case. SMS affects up to 70% of the astronauts during the first 3 days in space. The search for effective countermeasures has led to several nonpharmacological and pharmacological approaches.
