To study the association between ventilatory function and cognitive and behavioral impairment in ALS patients accounting for the effects of pertinent covariates. : Four hundred and eighty-one patients were identified from the Mayo Clinic Florida ALS registry who had concurrent forced vital capacity (FVC) and cognitive and behavioral testing using the ALS Cognitive Behavioral Screen (ALS-CBS). Multiple linear regression analysis was used to study the effects of FVC and relevant covariates on the ALS-CBS cognition score, subscores, and caregiver behavioral inventory. : FVC was positively correlated to the cognitive and behavioral subscores on the ALS-CBS ( < 0.001), and the correlation was independent of the effects of site of ALS onset, age, and years of education. : Cognitive and behavioral function may be adversely affected by ventilatory impairment in ALS. The presence of cognitive and behavioral impairment warrants a detailed assessment of ventilatory function.

The origins of resting-state functional MRI (rsfMRI) signal fluctuations remain debated. Recent evidence shows coupling between global cortical rsfMRI signals and cerebrospinal fluid inflow in the fourth ventricle, increasing during sleep and decreasing with Alzheimer's disease (AD) progression, potentially reflecting brain clearance mechanisms. However, the existence of more complex brain-ventricle coupling modes and their relationship to cognitive decline remains unexplored.

This leads to a state of relative inhibition, reducing feedforward gamma (40-90 Hz) rhythms and spiking to predictable inputs. We refer to this model as predictive routing.

Object handover is a fundamental task for collaborative robots, particularly service robots. In in-home assistance scenarios, individuals often face constraints due to their posture and declining physical functions, necessitating high demands on robots for flexible real-time control and intuitive interactions. During robot-to-human handovers, individuals are limited to making perceptual judgements based on the appearance of the object and the consistent behaviour of the robot.

The dissociation between conscious and unconscious perception is one of the most relevant issues in the study of human cognition. While there is evidence suggesting that some stimuli might be unconsciously processed up to its meaning (e.g.

Despite pictures being static representations, they use various cues to suggest dynamic motion. To investigate the effectiveness of different motion cues in conveying speed in static images, we conducted 3 experiments. In Experiment 1, we compared subjective speed ratings given for motion lines trailing behind movers, suppletion lines replacing parts of the movers and backfixing lines set in the background against the baseline of having no extra cue.
