“…Hence, our data are not in contradiction with, but refine, gesture observation and simulation studies suggesting that a similar dorsal network may be involved for visually-perceived novel and familiar gestures when the aim of the visual perception is to imitate [Decety et al, 1997;Grèzes et al, , 1999. Activation of the dorsal network during imitation is consistent with studies showing that the parietal cortex houses transformational processes linking perception to action [Andersen et al, 1997;Freund, 2001;Goodale and Haffenden, 1998;Goodale and Milner, 1992], participates in sensorimotor integration by maintaining an internal representation of the body's state as predicted by computational models ], and is involved in mental transformations of the body-inspace [Bonda et al, 1995[Bonda et al, , 1996a.…”

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.

“…The visuomotor measure involved localizing the remembered target using a manual-pointing paradigm in which observers were unable to see their hand or arm. Because the visuomotor system is believed to operate in real time (Milner & Goodale 1995), signi¢-cantly delayed actions directed at remembered targets are thought to rely on stored perceptual memories (Goodale & Ha¡enden 1998;Hu et al 1999a,b;Milner 1999). For this reason, localization measures were made both with and without a signi¢cant delay (4 s) following the stimulus presentation.…”

When a visual stimulus is continuously moved behind a small stationary window, the window appears displaced in the direction of motion of the stimulus. In this study we showed that the magnitude of this illusion is dependent on (i) whether a perceptual or visuomotor task is used for judging the location of the window, (ii) the directional signature of the stimulus, and (iii) whether or not there is a signi¢cant delay between the end of the visual presentation and the initiation of the localization measure. Our stimulus was a drifting sinusoidal grating windowed in space by a stationary, two-dimensional, Gaussian envelope ( 1 cycle of sinusoid). Localization measures were made following either a short (200 ms) or long (4.2 s) post-stimulus delay. The visuomotor localization error was up to three times greater than the perceptual error for a short delay. However, the visuomotor and perceptual localization measures were similar for a long delay. Our results provide evidence in support of the hypothesis that separate cortical pathways exist for visual perception and visually guided action and that delayed actions rely on stored perceptual information.

“…The circles of large and small disks create the Titchener illusion: The center disk appears smaller in the presence of the large outer disks and vice versa. It has been shown that perception, but not action, is affected by this illusion (Aglioti, Goodale, & DeSouza, 1993;Goodale & Haffenden, 1998). However, in these studies, perceptual judgments were not related to action.…”

“…For instance, you may look at a cup of coffee to grasp it or look at the cup to see if you should ask for a refill. Milner and Goodale's (1995;Goodale & Haffenden, 1998;Goodale & Humphrey, 1998) argument can be summarized by stating that for these different encounters vision may be distinct. On the basis of neurological and behavioral evidence, Milner and Goodale argued that the dorsal stream of the visual cortex, which is proposed to support visual control of movement (i.e., action), is separate from, but interacts with, the ventral stream, proposed to support perception.…”
