Volitional Inhibition and Brain–Machine Interfaces: A Mandatory Wedding

Volitional Inhibition and Brain–Machine Interfaces: A Mandatory Wedding

(reactive control), but also provides signals enabling the subject to adopt a response strategy which takes into account the context in which he or she operates. This form of cognitive control over response execution, named proactive control, adjusts the response selection and preparation process in anticipation of known task demands, driven by endogenous signals. Several lines of evidence indi...

Volitional control of neural activity: implications for brain-computer interfaces.

Successful operation of brain-computer interfaces (BCI) and brain-machine interfaces (BMI) depends significantly on the degree to which neural activity can be volitionally controlled. This paper reviews evidence for such volitional control in a variety of neural signals, with particular emphasis on the activity of cortical neurons. Some evidence comes from conventional experiments that reveal v...

Intracortical inhibition during volitional inhibition of prepared action.

Volitional inhibition is the voluntary prevention of a prepared movement. Here we ask whether primary motor cortex (M1) is a site of convergence of cortical activity associated with movement preparation and volitional inhibition. Volitional inhibition was studied by presenting a stop signal before execution of an anticipated response that requires a key lift to intercept a revolving dial. Motor...

Distinct Neural Correlates for Volitional Generation and Inhibition of Saccades

The antisaccade task has proven highly useful in basic and clinical neuroscience, and the neural structures involved are well documented. However, the cognitive and neural mechanisms that mediate task performance are not yet understood. An event-related fMRI study was designed to dissociate the neural correlates of two putative key functions, volitional saccade generation and inhibition of refl...
