“…Korosec and Pirtosek [1] and Berardelli et al [2] did not observe a BP preceding blepharospasms. Such fact reinforces the theory that BP precedes only conscious movements, even existing an unconscious and conscious planning of the voluntary motor act [5,6].…”

“…Libet showed that this "W judgment" occurred some 200 ms prior to movement onset, but, more importantly, he also showed that the preparatory brain activity that precedes voluntary action, the socalled "readiness potential," itself preceded the "W judgment" by several hundred milliseconds. Such readiness potentials arise in the premotor regions of cortex, including both the supplementary motor area (SMA) and the presupplementary motor area (pre-SMA), regions that have been linked to the planning and preparation of intentional, goal-directed, actions and sequences of actions (Deecke & Kornhuber, 1978).Haggard has argued that conscious awareness of our intention to act arises during the preparatory processes that precede an action, and is linked to the joint activity of premotor and parietal brain areas (Haggard, 2005).In support of this view, he has shown that patients with damage to the parietal cortex show a specific impairment in reporting when they became aware of their intention to move (i.e., Libet's "W judgment"). The proposal that the parietal cortex may maintain a dynamically updated state estimate of the current postural configuration of the body (the body schema) is well supported by neuropsychological (e.g., Wolpert, Goodbody, & Husain, 1998) and recent fMRI studies (e.g., Parkinson, Condon, & Jackson, 2010;Pellijeff, Bonilha, Morgan, McKenzie, & Jackson, 2006).…”

Several common neuropsychiatric disorders (e.g., obsessive-compulsive disorder, Tourette syndrome (TS), autistic spectrum disorder) are associated with unpleasant bodily sensations that are perceived as an urge for action. Similarly, many of our everyday behaviors are also characterized by bodily sensations that we experience as urges for action. Where do these urges originate? In this paper, we consider the nature and the functional anatomy of "urges-for-action," both in the context of everyday behaviors such as yawning, swallowing, and micturition, and in relation to clinical disorders in which the urge-for-action is considered pathological and substantially interferes with activities of daily living (e.g., TS). We review previous frameworks for thinking about behavioral urges and demonstrate that there is considerable overlap between the functional anatomy of urges associated with everyday behaviors such as swallowing, yawning, and micturition, and those urges associated with the generation of tics in TS. Specifically, we show that the limbic sensory and motor regions--insula and mid-cingulate cortex--are common to all of these behaviors, and we argue that this "motivation-for-action" network should be considered distinct from an "intentional action" network, associated with regions of premotor and parietal cortex, which may be responsible for the perception of "willed intention" during the execution of goal-directed actions.Keywords: Urge; Urge-for-action; Habit; Insula; Tourette syndrome; Action.Many of our everyday behaviors are characterized by bodily sensations that we experience either as an urge or a desire for action. For instance, we may experience a sensation that our bladder is full that is accompanied, to a greater or lesser extent, by an urge or desire to urinate (micturate). In extreme cases, this sense of fullness can be quite uncomfortable and the urge to urinate can be hard to suppress. Similarly, we may experience a tickle in our throat that is associated with an urge to cough or to swallow that can also be difficult to suppress voluntarily.However, not all urges for action are necessarily preceded by bodily sensations of which we are aware. For example, we may suddenly experience a strong urge to yawn, or even find ourselves yawning, without being aware of a sensory "trigger" for the action. In this paper, we consider the nature and the functional anatomy of these "urges-for-action," both in the context of everyday behaviors such as yawning, swallowing, and urinating, and in relation to clinical disorders in which the urgefor-action is considered pathological and substantially COGNITIVE NEUROSCIENCE, 2011, 2 (3-4), Commentaries, and Reply) Correspondence should be addressed to: Stephen R.

“…The RP, which is believed to arise from premotor and primary motor areas, is characterized by a slow negative going potential that starts approximately 1 second prior to movement onset, with maximum amplitudes at centrolateral recording sites (Ball et al, 1999;Cunnington et al, 2003;Deecke & Kornhuber, 1978;Deecke et al, 1987;Praamstra et al, 1996;Shibasaki et al, 1980). The RP is generally elicited prior to self-paced voluntary movements, but it has also been recorded in relation to stimulus-triggered movements (Castro et al, 2005;Kilner et al, 2004).…”

Recent evidence has shown that processing action-related language and motor action share common neural representations to a point that the two processes can interfere when performed concurrently. To support the assumption that language-induced motor activity contributes to action word understanding, the present study aimed at ruling out that this activity results from mental imagery of the movements depicted by the words. For this purpose, we examined cross-talk between action word processing and an arm reaching movement, using words that were presented too fast to be consciously perceived (subliminally). Encephalogram (EEG) and movement kinematics were recorded. EEG recordings of the "Readiness Potential" ("RP", indicator of motor preparation) revealed that subliminal displays of action verbs during movement preparation reduced the RP and affected the subsequent reaching movement. The finding that motor processes were modulated by language processes despite the fact that words were not consciously perceived, suggests that cortical structures that serve the preparation and execution of motor actions are indeed part of the (action) language processing network.
