“…Furthermore, neuropsychological evidence has indicated that damage to these same areas often results in ideomotor apraxia (IM), a disorder characterized by selective impairments in performing learned skilled actions not explained by elementary motor or sensory deficits or related to general problems with cognition, comprehension, or attention . Modern lesion analysis methods have consistently indicated that leftlateralized inferior parietal cortex, including supramarginal gyrus and surrounding intraparietal cortex, as well as inferior/ middle frontal gyri and surrounding precentral cortex, are sites of maximal lesion overlap in patients with IM and impaired performance of tool use pantomime (Haaland et al, 2000;Buxbaum et al, 2005;Goldenberg and Spatt, 2009). In summary, areas showing EXP-RS in the current study overlap closely with areas previously hypothesized to underlie the motoric aspects of skilled actions with tools.…”

fMRI Repetition Suppression for Familiar But Not Arbitrary Actions with Tools

For humans, daily life is characterized by routine interaction with many different tools for which corresponding actions are specified and performed according to well-learned procedures. The current study used functional MRI (fMRI) repetition suppression (RS) to identify brain areas underlying the transformation of visually defined tool properties to corresponding motor programs for conventional use. Before grasping and demonstrating how to use a specific tool, participants passively viewed either the same (repeated) tool or a different (non-repeated) tool. Repetition of tools led to reduced fMRI signals (RS) within a selective network of parietal and premotor areas. Comparison with newly learned, arbitrarily defined control actions revealed specificity of RS for tool use, thought to reflect differences in the extent of previous sensorimotor experience. The findings indicate that familiar tools are visually represented within the same sensorimotor areas underlying their dexterous use according to learned properties defined by previous experience. This interpretation resonates with the broader concept of affordance specification considered fundamental to action planning and execution whereby action-relevant object properties (affordances) are visually represented in sensorimotor areas. The current findings extend this view to reveal that affordance specification in humans includes learned object properties defined by previous sensorimotor experience. From an evolutionary perspective, the neural mechanisms identified in the current study offer clear survival advantage, providing fast efficient transformation of visual information to appropriate motor responses based on previous experience.

“…Thus Jeannerod (1994Jeannerod ( , 1995 proposed that such motor imagery tasks reflect the conscious experience of an inhibited premotor plan, which would be non-conscious if it were normally executed. Further, it seems that motor imagery is involved in predicting the consequences of an action, thus contributing to movement planning processes (Johnson 2000;Buxbaum et al 2005). Interestingly, a growing body of evidence suggests a left cerebral dominance for motor planning as shown in studies with participants with hemiparetic cerebral palsy (Mutsaarts et al 2005(Mutsaarts et al , 2007, with left hemispheric stroke (Rushworth et al 1998), apraxia (Goldenberg 1996;Hermsdörfer et al 1996;Weiss et al 2001), and also in participants without brain damage (Schluter et al 2001).…”

The brain processes associated with mental imagery have long been a matter of debate. Neuroimaging and neuropsychological studies have yielded diverging evidence of mental transformation activating the right hemisphere, the left hemisphere, or both. Here, using a mirror/normal discrimination task with rotated body parts (BPs) and external objects (EOs), we describe the case of a patient who developed a selective deficit in mental imagery of such BPs due to left posterior parietal brain damage. In addition, the patient's deficit predominated for pictures of right arms (i.e., arms corresponding to the patient's imagined contralesional arm) and was further characterised by an inability to distinguish between anatomically possible and impossible arm positions. This neuropsychological deficit was corroborated by neuroimaging evidence revealing the absence of activation in the left parietal lobe for the mental rotation of body parts as shown in healthy participants. In contrast, his behavioural performance and brain activation for EOs were similar to those of healthy participants. These data suggest that mental imagery of BPs and EOs relies on different cognitive and neural mechanisms and indicate that the left posterior parietal lobe is a necessary structure for mental transformations of human BPs.

We review three areas of research and theory relating to the involvement of motor processing in action observation: behavioural studies on imitation learning, behavioural work on short-term visuomotor interactions, and related neurophysiological and neuroimaging work. A large number of behavioural studies now indicate bi-directional links between perception and action: visual processing can automatically induce related motor processes, and motor actions can direct future visual processing. The related concept of direct matching (Rizzolatti et al., 2001) does not, however, imply that observed actions are transduced into a corresponding motor representation that would guarantee an instant and accurate imitation. Rather, studies on the mirror neuron system indicate that action observation engages the observer's own motor prototype of the observed action. This allows for enhanced action recognition, imitation recognition, and, predominantly in humans, imitation and observational learning. Despite the clear impact of action observation on motor representations, recent neuroimaging work also indicates the overlap of imitation learning with processes of non-imitative skill acquisition.
