Motor units (MUs), which compose spinal motor neurons and their innervated muscle fibers, are the fundamental unit of motor control. For nearly one hundred years, researchers have studied how MUs are recruited during movement, and the textbook understanding is that a simplified control strategy is used. A single…

The dorsal anterior cingulate cortex (dACC) has been studied extensively using effort-based decision-making (EBDM) paradigms and has been shown to track effort costs. However, it remains unclear whether the dACC encodes objective measures of effort, such as energy expenditure, or subjective perceptions of effort.…

The Ruhr Hand Motion Catalog of Human Center-Out Transport Trajectories [1] is a compilation of three-dimensional task-space motion data simultaneously measured by two motion tracking systems. The first one, an optical motion capture system, provided robust reference data. The second recording system consisted of a…

The upper limbs are essential for performing everyday tasks that require a wide range of motion and precise coordination. Planning and timing are crucial to achieve coordinated movement. Sensory information about the target and current body state is critical, as is the integration of prior experience represented by…

Wobble board-based Exergaming of different intensities provides a unique approach to enhance different cognitive and balance parameters . This study aims to determine that which of the cognitive and balance components are greatly affected by wobble board exergaming of different intensities in individuals with mild…

Gait disturbances in Parkinson's Disease (PD) are highly susceptible to changes in patients' surrounding environment. It is empirically known that the gait disturbances tend to become worse in environments with doors, obstacles, or narrow pathways, often causing freezing of gait (FoG). FoG is defined as a state in…

Except for maintaining weight and reducing health risks during childhood, physicalactivity is important for enhancing children’s mental functioning and cognitive development. Executive function (EF) constitutes supervisory control of cognitive functions to achieve a goal and is mediated via prefrontal cortex circuitry…

Aims: Converging evidence indicates beneficial effects of aerobic exercise on motor learning performance. Underlying mechanisms might be an impact of aerobic exercise on neuroplasticity and cortical excitability. Evidence suggests that motor learning and cortical excitability alterations correlate with the intensity…

An open question in neuroscience is how the brain controls naturally generated movements. An increasing number of studies have shown that high-dimensional neural population dynamics lie within low-dimensional manifolds, which may be integral to neural control of behavior. However, many of these studies have focused on…

According to a classical control-theoretic perspective on self-movement, our brains pilot our bodies to achieve goals, sometimes using open-loop predictive models and sometimes with closed-loop feedback. From this perspective, synchronization of self-motion with a moving target is a simple control problem, where error…

How does the motor cortex (MC) achieve generalizable and purposeful movements from the complex non-linear musculoskeletal system? This understanding can help us uncover how does the cortical activity relates to the movement. To elucidate this relationship, we build a model of the MC with realistic properties. To mimic…

How does the motor cortex achieve generalizable and purposeful movements from the complex, nonlinear musculoskeletal system? ​​Previous research in this field has focused on developing dimensionality reduction and modeling techniques to elucidate the structure in high-dimensional neural activity, and relate this…

A prevailing view of the role motor cortex plays in movement execution is that it’s limited to certain tasks, such as those involving novel muscle activation-patterns. Yet the relevant experimental support remains tenuous and the specific movement features that necessitate motor cortical involvement remain unclear.…
