“…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). While it is clearly the case that in such experiments individuals can report when they first perceived themselves to have formed an "intention" to move, it is another thing entirely to argue that such conscious "intentions" typically precede everyday actions.…”

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.

“…In humans, a broad frontoparietal network, likewise including strongly connected areas of the posterior parietal cortex (PPC) and dorsal premotor cortex (Tomassini et al 2007), is involved in the preparation of goal-directed reaching movements (Prado et al 2005;Beurze et al 2007;Busan et al 2009;Lindner et al 2010;Parkinson et al 2010; for a review see Culham et al 2006). Consistent with electrophysiological findings in monkeys, the human PPC and PMd have been demonstrated to represent both the spatial location of the movement goal and the effector selected for that action, e.g., left vs. right arm (Beurze et al 2007).…”

“…Within the human PPC, a dorsomedial area of the SPL seems to be crucially involved in the planning of hand and arm movements and has been discussed as a putative human homolog of monkey area PRR (Astafiev et al 2003;Connolly et al 2003;Pellijeff et al 2006;Fernandez-Ruiz et al 2007;Hagler et al 2007;Vesia and Crawford 2012). Consistent with previous reports on monkey PRR (e.g., Snyder et al 1997), the "human PRR" elicits higher activation for the planning of goal-directed pointing movements compared with the planning of goal-directed saccades (Connolly et al 2003).…”

“…E-mail: stephen.jackson@nottingham.ac.uk Condon, & Jackson, 2010;Pellijeff, Bonilha, Morgan, McKenzie, & Jackson, 2006), suggest that the posterior parietal cortex may play a particularly important role in maintaining an accurate and up-to-date representation of the current postural state of the body (the body schema). Furthermore, it is suggested that this body schema mechanism plays a key role in the mental transformation of bodily representations during mental imagery.…”
