Summary: This study proposed a compound-limbs EEG-BCI paradigm that takes into account the cooperation of upper and lower limbs during walking, aiming to achieve more natural control of lower-extremity powered exoskeletons. Experimental results showed that the proposed paradigm had high classification accuracy, providing a potential method for decoding human stepping intention and enabling natural control of walking assistance devices.

Summary: This study investigates the influence of handedness on brain activation during the processes of imagining and executing simple hand movements. The results show that both left-handed and right-handed individuals exhibit activation over sensorimotor areas. However, the right-handed group tends to display more bilateral patterns than the left-handed group, which contradicts previous findings. Additionally, there is a stronger activation during motor imagery than during motor execution in both groups.

Summary: This study investigated the effects of priming iTBS on poststroke hemiparetic upper limb recovery. The results showed that priming and nonpriming iTBS were both superior to sham stimulation in enhancing treatment gains from robot-assisted training. Priming iTBS may facilitate poststroke motor learning, especially for patients with a higher functioning upper limb.

Summary: Individuals with chronic stroke showed poorer fine and gross motor hand dexterity in their ipsilesional hand compared to controls and normative values, but performed significantly better than their contralesional hand. These findings suggest residual deficits in hand manipulation abilities post-stroke.

Summary: Motor brain-computer interface (BCI) decodes voluntary motion intentions from brain signals and produces control commands without activating peripheral nerves and muscles. It has important applications in neurorehabilitation and daily-life assistance for motor-impaired patients. Recent studies have focused on neural signatures, movement decoding, and applications of motor BCIs. This review provides a comprehensive overview of EEG signals-based motor BCIs, particularly for upper limb movements, discussing experimental paradigms, techniques, and application systems. It also highlights the development of more natural and practical upper-limb motor BCIs by addressing key issues such as target-users orientation, distraction robustness, and multi-limbs motor BCIs.

Summary: In this systematic review, tactile functions showed a moderate to high association with upper limb motor function in individuals living with cerebral palsy; however, the association between proprioceptive and visual functions remains unclear. The heterogeneity of the results limits the ability to draw definitive conclusions, highlighting the need for further research to determine the relative contribution of various sensory modalities to motor functions.

Summary: Current clinical practice has not effectively utilized EEG measurements in predicting post-stroke recovery in stroke patients. However, research suggests that certain EEG measures show promise in predicting upper limb motor outcome after stroke. This literature review examined various quantitative and qualitative EEG-based measures in relation to stroke timeframe and experimental tasks, and identified event-related measures as the most promising for prediction.

Summary: This study proposes a method that combines signal traceability and Riemannian geometric features to identify six motor intentions of the same upper limb. The method successfully improves the accuracy of intent recognition and addresses the issue of temporal variability in EEG data for active Brain-Machine Interfaces.

Summary: The execution of voluntary movements is primarily controlled by the opposite cerebral hemisphere. Previous research has shown that the ipsilateral motor network plays a crucial role in the planning and execution of limb movements. However, the specific functions and interactions of this network in different task contexts are still not fully understood.

Summary: Healthy aging leads to poorer performance in upper limb daily living movements. Two non-invasive neuroimaging methods, functional near-infrared spectroscopy (fNIRS) and electroencephalography (EEG), were used in this study to evaluate the neural correlates of functional proximal upper limb movements. The results showed age-related changes in brain electrical and hemodynamic response patterns. This study suggests that combined fNIRS-EEG could be used to monitor movement-related neuroplasticity in clinical practice.

Summary: This study aimed to investigate the clinical characteristics and neural bases of chronic and severe upper-limb motor deficits. Principal component analysis showed that the clinical characteristics could be described as a comprehensive severity and a trade-off relationship. Lesion analyses revealed that the severity was correlated with corticospinal tract integrity, and the trade-off relationship was associated with the integrity of other white matter.

Summary: This study investigates the early, intermediate, and late stages of motor learning in percussion performance, specifically on marimba. The results indicate that temporal control of mallet movements improves in the intermediate learning session, while spatial variability in the left and right elbows decreases. These findings suggest a relationship between temporal control and spatial variability in motor learning in percussion.

Summary: The purpose of this study was to clarify the characteristics of the upper limb stretch reflex in wrestlers. The experiment involved 10 wrestlers and 11 control subjects, and the results showed that high-level wrestlers have specific characteristics of the long-latency stretch reflex in the triceps brachii that are modulated in a situation-specific manner. There was no significant difference in the reflex of the biceps brachii.

Summary: This study found that both motor and tactile sensory impairments can predict the treatment response to neurorehabilitation in patients with moderate to severe paralysis after chronic-phase stroke. Tactile sensory impairment predicts improvement in hand function, while motor impairment predicts improvement in the quality of hand movements.

Summary: The human visual system possesses predictive capabilities, with the brain building predictive internal models to adapt to dynamic environments. In a study disrupting people's internal models, it was found that individuals were better at predicting shot outcomes and tracking the ball's position while watching upright videos, with enhanced brain activity in occipital regions. This suggests that accurate predictive models enable individuals to better focus on relevant information and suppress irrelevant stimuli, leading to improved predictive performance and inhibited information processing.

Summary: One of the key findings of cognitive neuroscience is that the power of occipital alpha-band brain waves increases when people close their eyes. This increase in alpha power is believed to reflect the default state of the visual brain in the absence of external input. However, this study presents evidence that the power of alpha oscillations can be further increased by pre-adaptation to radial motion when the eyes are closed.

Summary: This study examined the effects of calorie labelling and contextual factors (reflective motivation and habits) on the calorie content of coffee-shop menu choices. The results showed that labelling did not significantly affect the total calorie content of items selected. However, reflective motivation had a moderating effect, with less motivated participants showing greater calorie selection when exposed to labelling. Participants with weaker habits took longer to select items, but were not more influenced by labelling. Higher reflective motivation was associated with selecting fewer calories and better estimating calorie content.

Summary: This study investigated the association between two different measures of schizotypy and symptoms of depression and anxiety in a sample of university students. The results indicated that persecutory ideation was a strong predictor of anxiety, depression, and stress sensitivity, while the dimensions of no close friends and social anxiety predicted psychological distress and stress.

Summary: This study used the auditory roving oddball paradigm to investigate the impact of self-reported anxiety on event-related potential (ERP) activity related to sensory gating and mismatch negativity (MMN). The findings suggest that individuals with high trait anxiety demonstrate increased vigilance towards deviant tones, while increased state anxiety is associated with a reduced ability to filter out irrelevant stimuli.

The results showed that perfectionistic concerns were uniquely associated with anxiety reactivity, while perfectionistic strivings were not related to an increase in anxiety reactivity.
