Murray R, Neumann M, Forman MS, et al.:.: Cognitive and motor assessment in autopsy-proven corticobasal degeneration. Neurology 2007, 68:1274-1283. This article describes the cognitive and motor features of CBD. Its major strengths include use of autopsy-proven cases and a finegrained analysis of cognitive function. The authors show that CBD patients have a specific profile of cognitive impairment related to the neuroanatomic distribution of disease. (Pubitemid 46625973)

Cortico-cortical networks in patients with ideomotor apraxia as revealed by EEG coherence analysis
-
Wheaton LA, Bohlhalter S, Nolte G, et al.: Cortico-cortical networks in patients with ideomotor apraxia as revealed by EEG coherence analysis. Neurosci Lett 2008, 433:87-92. This study used EEG coherence, a type of connectivity analysis that establishes a network of structures defined by temporally related areas of cortical activity. In patients with apraxia due to stroke or CBD, the authors showed involvement of right hemisphere structures in a praxis network. This finding has important implications for right hemisphere capacity for praxis and ability to mediate recovery.

Left inferior parietal representations for skilled hand-object interactions: Evidence from stroke and corticobasal degeneration
-
Buxbaum LJ, Kyle K, Grossman M, Coslett HB: Left inferior parietal representations for skilled hand-object interactions: evidence from stroke and corticobasal degeneration. Cortex 2007, 43:411-423. The authors provide a model of praxis that emphasizes the role of body knowledge and how it is incorporated in a dynamic way as motor programs are translated into action. Their model predicts different patterns of praxis behavior in patients with CBD versus those with left parietal stroke. They also discuss the inferior parietal lobe as an integrator of object knowledge and body representations. (Pubitemid 46744681)

Wheaton LA, Nolte G, Bohlhalter S, et al.:.: Synchronization of parietal and premotor areas during preparation and execution of praxis hand movements. Clin Neurophysiol 2005, 116:1382-1390. Using EEG coherence, the authors demonstrate functional connectivity between the frontal and parietal cortex during task performance. This type of study is vital for identifying neural networks underlying praxis. (Pubitemid 40839346)

The mirror neuron system and the consequences of its dysfunction
-
Iacoboni M, Dapretto M: The mirror neuron system and the consequences of its dysfunction. Nat Rev Neurosci 2006, 7:942-951. The mirror neuron system provides an empirically based account for the intimate connection between frontal and parietal regions. This review catalogues critical functions of the frontoparietal system. For example, interruption of the mirror neuron system may result in apraxia by interfering with the intention to grasp.

White matter changes in corticobasal degeneration syndrome and correlation with limb apraxia

DOI 10.1001/archneur.65.6.796
-
Borroni B, Garibotto V, Agosti C, et al.:.: White matter changes in corticobasal degeneration syndrome and correlation with limb apraxia. Arch Neurol 2008, 65:796-801. This study imaged both gray and white matter to characterize structural abnormalities in patients with CBD. The authors showed cortical atrophy in frontoparietal areas and disruption of association fibers within and between these regions, which they correlated with apraxia. These findings again emphasize that the neural correlate of praxis is best understood as a network of structures. (Pubitemid 351831458)
