Cortico-muscular control of postural balance in older adults - effects of training on functional connectivity

This study examines how balance training in older adults affects cortico-muscular functional connectivity during postural recovery, finding training-induced changes in beta-band coherence with muscle synergies.

Age-related differences in the cortical motor network during uni-manual and bimanual coordination - an EEG study

This study examines age-related differences in cortical motor network activity during unimanual and bimanual coordination using EEG, finding that older adults show reduced performance and altered alpha and beta activity in specific brain regions.

Machine learning approaches to predicting whether muscles can be elicited via TMS

This paper uses machine learning to predict motor evoked potential (MEP) presence from TMS setup parameters, achieving up to 90% accuracy within subjects.

Overlap in the cortical representation of hand and forearm muscles as assessed by navigated TMS

This study examines cortical representation overlap between hand and forearm muscles using navigated TMS and finds greater overlap in synergistic muscle pairs.

Predicting vertical ground reaction forces from 3D accelerometry using reservoir computers leads to accurate gait event detection

This paper uses reservoir computers to predict vertical ground reaction forces from accelerometry, enabling accurate gait event detection during walking and running.

Accounting for stimulations that do not elicit motor-evoked potentials when mapping cortical representations of multiple muscles

This study shows that including non-MEP points in TMS mapping can affect estimates of cortical motor areas, suggesting conventional methods may overestimate excitability regions.

Ankle muscles drive mediolateral center of pressure control to ensure stable steady state gait

The paper identifies an ankle strategy during steady-state walking where ankle moments correct for foot placement errors and influence subsequent foot placement.

Effect of aging-related network changes on unimanual sensorimotor learning - a simultaneous EEG-fMRI study

This study investigates how aging-related network changes affect unimanual motor learning using simultaneous EEG-fMRI, finding reduced beta power and altered inhibitory interactions in older adults.

Active foot placement control ensures stable gait: Effect of constraints on foot placement and ankle moments

The paper investigates how foot placement and ankle moments contribute to gait stability during walking under different constraints.

Dynamic Functional Connectivity between Order and Randomness and its Evolution across the Human Adult Lifespan

The paper analyzes dynamic functional connectivity (dFC) in fMRI data from healthy elderly, finding that dFC slows down and becomes less complex with aging, correlating with cognitive performance.

Network structure of the human musculoskeletal system shapes neural interactions on multiple timescales

The paper uses network analysis to show that anatomical constraints shape functional connectivity between muscles during postural tasks.

Comparing average network signals and neural mass signals in systems with low-synchrony

This study compares neural mass models and average network signals in low-synchrony systems, finding that neural mass models work well for large, synchronized networks but fail when connections are sparse.

Functional connectivity in neuromuscular system underlying bimanual muscle synergies

The paper investigates how corticomuscular and intermuscular coherence contribute to bimanual muscle synergies by manipulating visual feedback sensitivity in healthy participants.
