To date, hampered physiological function after exposure to microgravity has been primarily attributed deprived peripheral neuro-sensory systems. For the first time, this study elucidates alterations in human brain long-duration spaceflight. More specifically, we found significant differences resting-state functional connectivity between motor cortex and cerebellum, as well changes within default mode network. In addition, cosmonaut showed supplementary areas during a imagery task. These...
Significance Long-duration spaceflight induces detrimental changes in human physiology due to microgravity. One example is a cephalic fluid shift. Here, we prospectively investigated the quantitative cerebrospinal (CSF) volume of brain ventricular regions space crew by means region interest, observer-independent analysis on structural MRI scans. scans were collected before mission, shortly after and 7 mo return Earth. We found significant increase lateral third ventricles at postflight trend...
The present study reports alterations of task-based functional brain connectivity in a group 11 cosmonauts after long-duration spaceflight, compared to healthy control not involved the space program. To elicit postural and locomotor sensorimotor mechanisms that are usually most significantly impaired when travelers return Earth, plantar stimulation paradigm was used block design fMRI study. motor system activated by precentral postcentral gyri, SMA, SII/operculum, and, lesser degree, insular...
Spaceflight causes persisting sensorimotor neuroplasticity and reversible gray matter morphological changes.
Long-duration spaceflight induces changes to the brain and cerebrospinal fluid compartments visual acuity problems known as spaceflight-associated neuro-ocular syndrome (SANS). The clinical relevance of these whether they equally affect crews different space agencies remain unknown. We used MRI analyze alterations occurring in perivascular spaces (PVS) NASA European Space Agency astronauts Roscosmos cosmonauts after a 6-mo on International Station (ISS). found increased volume basal ganglia...
Aging is known to be associated with a decline in interoceptive abilities and changes emotional processing, including alexithymia. As the brain areas supporting awareness participate perception of emotion, we suggested that alexithymia older adults may share common neural ground. To test this hypothesis, administered functional magnetic resonance imaging-based heartbeat detection task 62 diverse ages (range 18-73) evaluated larger sample younger using questionnaires characterizing...
Humans undergo extreme physiological changes when subjected to long periods of weightlessness, and as we continue become a space-faring species, it is imperative that fully understand the occur in human body, including brain. In this study, present findings brain structural associated with long-duration spaceflight based on diffusion magnetic resonance imaging (dMRI) data. Twelve cosmonauts who spent an average six months aboard International Space Station (ISS) were scanned MRI scanner...
The prospect of continued manned space missions warrants an in-depth understanding how prolonged microgravity affects the human brain. Functional magnetic resonance imaging (fMRI) can pinpoint changes reflecting adaptive neuroplasticity across time. We acquired resting-state fMRI data cosmonauts before, shortly after, and eight months after spaceflight as a follow-up to assess global connectivity over Our results show persisting decreases in posterior cingulate cortex thalamus increases...
Despite the increasing popularity of neurofeedback, its mechanisms action are still poorly understood. This study aims to describe processes underlying implicit electroencephalographic neurofeedback. Fifty-two healthy volunteers were randomly assigned a single session infra-low frequency neurofeedback or sham with electrodes over right middle temporal gyrus and inferior parietal lobule. They observed moving rocket, speed which was modulated by waveform derived from band-limited filter....
The ability to adopt different perspectives, or vantage points, is fundamental human cognition, affecting reasoning, memory, and imagery. While the first-person perspective allows individuals experience a scene through their own eyes, third-person involves an external viewpoint, which thought demand greater cognitive effort neural processing. Despite frequent use of switching across various contexts, including modern media in therapeutic settings, mechanisms differentiating these two...
<p><strong>Context and relevance.</strong> To date, the study of brain correlates working memory (WM) is associated with a number theoretical as well methodological difficulties. Firstly, substantially variable tasks are used to assess WM. Secondly, each neuroimaging method has its own characteristics limitations. <strong>Objective.</strong> The aim this paper was systematize WM, analyze these paradigms in terms possibility feasibility their parallel use fMRI...
Individual variability in imagery experiences has long attracted the interest of philosophers, educators, and psychologists. Since Aristotle’s time, it was assumed that is a universal ability, so everyone possesses it. Galton first measured vividness subjective experiences, discovered some individuals reported zero imagination. Recent research coined term “aphantasia” — an inability to form mental imagery, or having “blind mind’s eye” (Zeman, Dewar, & Della Sala, 2015). We argue there...
Aging is associated with decreased functional connectivity in the main brain networks, which can underlie changes cognitive and emotional processing. Neurofeedback a promising non-pharmacological approach for enhancement of connectivity. Previously, we showed that single session infra-low frequency neurofeedback results increased between sensory processing networks healthy young adults. In current pilot study, aimed to evaluate possibility enhancing during aging use neurofeedback. Nine...
The paper reviews N.A. Berstein’s creative legacy in the development of Russian research visual perception and attention starting from 1960s. It describes how these studies adopted four groups concepts Bernstein’s biocybernetics: first, metaphor movement construction; second, concept task; third, idea levels (hierarchy) fourth, principle feedback or circular control movement. also discusses modern level-based that directly originated ideas. traces parallels between psychology regulation...
In the general concept of self-disturbances in schizophrenia and spectrum disorders, somatopsychic depersonalization (SPD) occupies a special place as it constitutes syndrome that comprises feelings detachment from one's own body mental processes. However, apart clinical descriptions, to date pathophysiology SPD is not fully understood due rareness lack experimental studies. case study one patient with schizotypal disorder, we applied multimodal approach understanding phenomena. The...
The claim that temporal aspects of perception are sensitive to top-down influences is supported by several pieces evidence regarding order. This includes modulations displacements attention (the prior entry effect; Titchener, 1908) and schemata obtained from experience (Pechenkova, 2008; Caldwell-Harris & Morris, 2008). Would there be similar in simultaneity succession? To answer this question, we tested potential effects two methods stimuli grouping. In the first experiment, left right...
