16. To select one hand while using both : neural mechanisms supporting flexible hand dominance in bimanual object manipulation
Abstract : In daily activities, the brain regularly assigns different roles to the hands dependingon task and context. Yet, little is known about the underlying neural processes. Thiscertainly applies to how the brain, where each hemisphere primarily controls onehand, manages the between-hand coordination required in bimanual objectmanipulation. READ MORE

17. Neck function in rhythmic jaw activities
Abstract : Previous studies in animals and humans show anatomic and physiological connections between the trigeminal and cervical regions. This investigation tested the hypothesis of a functional integration between the human jaw and neck motor systems in rhythmic jaw activities. READ MORE

18. Attention-deficit/hyperactivity disorder : alterations of motor behaviour and dopaminergic transmission
Abstract : Altered catecholaminergic neurotransmission in the brain has long been thought to be of importance in the regulation of motor behavior and cognitive performance in children who had symptoms of distractability, impulsivity and clumsiness. The dopamine theory of AD/HD has mainly been substantiated by: i) the effects of psychostimulants, which target the dopamine transporter (DAT), and thereby reduce impulsiveness and inattentiveness, increase the striatal cerebral blood flow and functional activity, and ii) the evidence from linkage studies associating the AD/HD syndrome with allelic variations of genes encoding the dopamine transporter and, possibly, the dopamine D4 receptors.

19. Role of the dopamine system in motor skill learning : implications for neurodevelopmental disorders
Abstract : Dopamine (DA), released by midbrain neurons, is critical for motor performance, motor skill learning, and corticostriatal synaptic plasticity. Dysregulation of DAergic signaling in corticostriatal circuitry has also been implicated in several highly heritable neurodevelopmental disorders, such as attention/deficit hyperactivity disorder (ADHD), which are often associated with deficits in fine motor skills.

20. High-Density Electromyography-Based Methods for Joint Torque Prediction and Motor Unit Behavior Observation
Abstract : Electromyography (EMG) is a technique that measures the electrical activity of muscles. It reflects muscle activation and provides an interface to the central nervous system at the level of the muscle or individual motor units, which helps us understand the mechanisms of muscle force production, control, and coordination.
