“…This finding may provide a physiological basis for the neurological observations that lesions in the left hemisphere that include inferior parietal cortices often cause ideomotor apraxia (Liepmann, 1905;Schnider et al, 1997;Haaland et al, 2000;Leiguarda and Marsden, 2000;Goldenberg, 2003;Johnson-Frey, 2004). The apraxia after left parietal damage is often present when using either hand (Alexander et al, 1992;Haaland and Harrington, 1996;Leiguarda and Marsden, 2000;Halsband et al, 2001).…”

“…Thus, we hypothesized that the somatic sensation of hand-object interactive movements should be associated with activity in some of the frontoparietal areas related to active manipulation of objects, just like the sensation of hand movement involves activation of the primary motor cortex (Naito et al, 1999(Naito et al, , 2002bNaito, 2004). We also predicted a dominance of the left hemisphere, because damages to the left frontoparietal cortices often cause apraxia of tool use (Liepmann, 1905;Schnider et al, 1997;Haaland et al, 2000;Leiguarda and Marsden, 2000;Goldenberg, 2003;Johnson-Frey, 2004). We used functional magnetic resonance imaging (fMRI) to test these hypotheses.…”

Manipulation of objects and tool-use are known to be controlled by a network of frontal motor and parietal areas. Here, we investigate which of these areas are associated with the somatic sensation of hand-object interactive movement using functional magnetic resonance imaging.To dissociate the sensation of movement from the motor control commands, we used a new kinesthetic illusion. Twelve blindfolded right-handed participants placed the palm of their right or left hand on an object (a ball). Simultaneously, we vibrated the tendon of the wrist extensor muscle. This elicited the illusion that the wrist is flexing and the touched object is also moving along with the hand (hand-object illusion). As controls, we vibrated the skin surface over the nearby bone, which does not elicit any illusions, or we vibrated the tendon when the hand did not touch the object, which only generates the illusory flexion of the hand.We found that the hand-object illusion specifically activated the left inferior parietal lobule (IPL) (supramarginal gyrus and parietal operculum, including cytoarchitectonic areas ip1 and op1) and area 44. The left IPL was activated both during the hand-object illusions with the right and left hands, and the activity was greater than in the right corresponding parietal region, suggesting a dominant role of the left hemisphere.We conclude that the left IPL is involved in the somatic perception of hand-object interactive movement and suggest that the underlying mechanism is the somatic integration of internal information about the body and external information about the object.

Abstract:The present study aimed to ascertain the neuroanatomical basis of an influential neuropsychological model for upper limb apraxia [Rothi LJ, et al. The Neuropsychology of Action. 1997. Hove, UK: Psychology Press]. Regional cerebral blood flow was measured in healthy volunteers using H 2 15O PET during performance of four tasks commonly used for testing upper limb apraxia, i.e., pantomime of familiar gestures on verbal command, imitation of familiar gestures, imitation of novel gestures, and an action-semantic task that consisted in matching objects for functional use. We also re-analysed data from a previous PET study in which we investigated the neural basis of the visual analysis of gestures. First, we found that two sets of discrete brain areas are predominantly engaged in the imitation of familiar and novel gestures, respectively. Segregated brain activation for novel gesture imitation concur with neuropsychological reports to support the hypothesis that knowledge about the organization of the human body mediates the transition from visual perception to motor execution when imitating novel gestures [Goldenberg Neuropsychologia 1995;33:63-72]. Second, conjunction analyses revealed distinctive neural bases for most of the gesture-specific cognitive processes proposed in this cognitive model of upper limb apraxia. However, a functional analysis of brain imaging data suggested that one single memory store may be used for "to-be-perceived" and "to-be-produced" gestural representations, departing from Rothi et al.'s proposal. Based on the above considerations, we suggest and discuss a revised model for upper limb apraxia that might best account for both brain imaging findings and neuropsychological dissociations reported in the apraxia literature.

“…From neuropsychological studies it is well known that apraxic patients are selectively disturbed for different command modalities (e.g., Schnider, Hanlon, Alexander, & Benson, 1997). On the one hand patients with ideomotor apraxia typically make the most errors on pantomime to verbal command, whereas imitation performance is less impaired or remains at least equally impaired (De Renzi, Motti, & Nichelli, 1980;Heilman & Rothi, 1985;Alexander et al, 1992).…”
