Investigating the Sophistication of Long-Latency Stretch Responses During Postural Control of the Upper Limb
(2011-01-18)
A recent theory of motor control, based on optimal feedback control, posits that voluntary motor behaviour involves the sophisticated manipulation of sensory feedback. Although this theory can explain how people move in ...
Investigating the sophistication of rapid corrective responses in the upper limb during reaching and postural control
(2014-04-29)
Everyday movements, such as reaching for a drink of water or typing on a keyboard highlight the relative ease with which we move and interact with our surroundings. However, the success of these skilled movements depends ...
Investigating Motor Encoding of Potential Reach Targets
(2015-10-03)
Neurophysiological and behavioural research has suggested that multiple potential actions are represented simultaneously. For example, neural activity associated with multiple potential actions has been observed in premotor ...
Rapid Adaptation of Reactive Force Control When Lifting Objects
(2013-02-04)
The control of object manipulation tasks involves the close interplay of predictive and reactive control mechanisms. For example, when lifting an object, people typically predict the weight based on object size and material ...
Sophisticated Feedback Processing in Motor Control
(2015-01-27)
Recent theories of motor control emphasize the role of sensory feedback in driving motor output and how feedback could be flexibly modulated to adapt to the behavioural requirements of a task. Here, we tested the merits ...
Motor Memories in Manipulation Tasks are Linked to Contact Events Between Objects
Humans have the remarkable ability to learn and perform motor skills, often involving the manipulation of different objects or tools, such as swinging a hammer or a tennis racket. The objects that we manipulate are usually ...
Coding body and world for reaching movements
To reach to visual targets, we need to transform the visual representation into the coordinate system of the moving arm, i.e. coordinate transformations. Varying body postures such as lying or rolling the head leads to ...
