Individual movement variability magnitudes are predicted by cortical neural variability
15 Humans exhibit considerable motor variability even across trivial reaching movements. This 16 variability can be separated into specific kinematic components such as extent and direction, which 17 are thought to be governed by distinct neural processes. Here, we report that individual subjects 18 exhibit different magnitudes of kinematic variability, which are consistent (within individual) ...
متن کاملNeural Variability Quenching Predicts Individual Perceptual Abilities.
Neural activity during repeated presentations of a sensory stimulus exhibits considerable trial-by-trial variability. Previous studies have reported that trial-by-trial neural variability is reduced (quenched) by the presentation of a stimulus. However, the functional significance and behavioral relevance of variability quenching and the potential physiological mechanisms that may drive it have...
متن کاملIntra-individual movement variability during skill transitions: a useful marker?
Applied research suggests that athletes and coaches need to be challenged in knowing when and how much a movement should be consciously attended to. This is exacerbated when the skill is in transition between two more stable states, such as when an already well-learnt skill is being refined. Using existing theory and research, this paper highlights the potential application of movement variabil...
متن کاملVariability in vancomycin levels in an intensive care population explained by variability in clearance
Methods In a prospective observational study we included patients started on vancomycin, from four different intensive care units (ICU) at Oslo University Hospital. Blood samples as well as ultrafiltrate samples from patients on continuous renal replacement therapy (CRRT), were collected in one dosage interval on three consecutive days 24 hours(hrs) from start. The observation time was 72 hrs. ...
متن کاملSuppression of cortical neural variability is stimulus- and state-dependent.
Internally generated, spontaneous activity is ubiquitous in the cortex, yet it does not appear to have a significant negative impact on sensory processing. Various studies have found that stimulus onset reduces the variability of cortical responses, but the characteristics of this suppression remained unexplored. By recording multiunit activity from awake and anesthetized rats, we investigated ...
