“…; e.g. [95][96][97]), and those involved in the selection and effective use of a functional tool to solve a mechanical problem [98,99]. Thus, human tool use activates a fronto-parietal praxis network involved in hand manipulation skills, as well as regions of the cerebellum and the basal ganglia [95], while macaque tool use also activates several cortical areas (intraparietal cortex, presupplementary motor area, premotor cortex) as well as the cerebellum and the basal ganglia [100].…”

Various authors have suggested behavioural similarities between tool use in early hominins and chimpanzee nut cracking, where nut cracking might be interpreted as a precursor of more complex stone flaking. In this paper, we bring together and review two separate strands of research on chimpanzee and human tool use and cognitive abilities. Firstly, and in the greatest detail, we review our recent experimental work on behavioural organization and skill acquisition in nut-cracking and stoneknapping tasks, highlighting similarities and differences between the two tasks that may be informative for the interpretation of stone tools in the early archaeological record. Secondly, and more briefly, we outline a model of the comparative neuropsychology of primate tool use and discuss recent descriptive anatomical and statistical analyses of anthropoid primate brain evolution, focusing on corticocerebellar systems. By juxtaposing these two strands of research, we are able to identify unsolved problems that can usefully be addressed by future research in each of these two research areas.

“…Patients with SD retain good problem-solving skills, as demonstrated, for example, by excellent performance on the Novel Tools test (Goldenberg & Hagmann, 1998) until late in the course of the disease Hodges, Spatt, & Patterson, 1999). It is perhaps surprising, then, that Hodges et al (2000) observed little evidence of trial-and-error explorations by the SD patients that might have helped them to work out the correct use of real objects.…”

“…Second, the ability to work out a plausible function for an object often requires knowledge about its properties (e.g., knowledge about the materials it is made from), which may also be impaired in these patients. A further possible factor is that the mechanicalproblem-solving test used in the previous study, the Novel Tool test (Goldenberg & Hagmann, 1998), can be accomplished purely through visual matching of the tools and the blocks, making it a nonstringent measure of real problem solving.…”

The 8 patients involved in this study were impaired on tests assessing knowledge of objects and on the demonstration of their use. The patients' success in object use was significantly correlated with their knowledge about the objects, providing further evidence that conceptual knowledge plays a key role in object use. Having a recipient present improved performance in the moderately impaired patients, suggesting that a certain level of conceptual knowledge must remain for the additional information to be beneficial. Although overall accuracy in using the target objects was not related to our measures of affordance, the specific aspects of use afforded by the objects' structures were relatively impervious to semantic impairment, suggesting a role for affordance information when object-specific knowledge is disrupted. The patients' familiarity with the objects was an important predictor of performance. Finally, despite good performance on tests of mechanical problem solving, the patients showed very little evidence of employing these skills in their interactions with real objects.

“…Approximately half of the apraxic patients had lesions encompassing the left IPL. In the remaining apraxic patients, lesions did not involve the left IPL itself, but were in other regions of the frontoparietal network including the cerebellum, thalamus, broca's area, and underlying white matter, that are heavily associated with disruption of left IPL function, apraxia and object-use deficits (Goldenberg & Hagmann, 1998;Johnson-Frey, 2004;Buxbaum et al, 2005;Buxbaum et al, 2007;Sunderland et al, 2011). A review of apraxia from subcortical damage found that of 82 cases, a majority of patients had lesions implicating the putamen, thalamus, basal ganglia, internal capsule, and periventricular and peristriatal white matter (Pramstaller & Marsden, 1996).…”

“…Depending on the type and severity of apraxia, errors are observed in one or all behaviours (Goldenberg, 1996;Buxbaum, 2001;Daprati & Sirigu, 2006). Apraxia can emerge from lesions across the motor network and is heavily associated with damage to the left IPL, most markedly when examining transitive movements (Goldenberg & Hagmann, 1998;Johnson-Frey, 2004;Buxbaum, Johnson-Frey, & Bartlett-Williams, 2005;Buxbaum, Kyle, Grossman, & Coslett, 2007;Sunderland, Wilkins, & Dineen, 2011).…”

Perceptual decisions regarding object manipulation are selectively impaired in apraxia or when tDCS is applied over the left IPL

This study evaluated whether apraxia can be understood as due to impaired motor representations or motor imagery necessary for appropriate object-use, imitation, and pantomime. The causal role of the left inferior parietal lobe (IPL), which is heavily implicated in apraxia, is also evaluated. These processes are appraised in light of the proposed ventro-dorsal sub-stream of the classic two visual pathway model, where perceptual information from the ventral stream and the dorsal action stream are integrated and essential for object manipulation. Using a task assessing object-use perception, stroke patients with apraxia demonstrated a selective deficit during perceptual decisions reliant on the integration of visible and known object properties to select the appropriate grasp for object-use. This deficit increased with apraxia severity. A dissociation was evident in these patients showing intact non-motoric perceptual decisions regarding the functional semantic relationship between two objects in the absence of the actor (e.g. how a hammer hits a nail). Converging evidence was found using a modified version of the same task in a neuromodulation study that directly targeted the left IPL in healthy participants using transcranial direct current stimulation (tDCS). Application of inhibitory stimulation over the left IPL reduced performance during perceptual decisions regarding object manipulation whilst performance was unaffected during functional semantic decisions. Excitatory stimulation of the left IPL did not affect performance in either task. Combined, these results suggest that the left inferior parietal lobe is critical for motor imagery, and that apraxia may be caused by an inability to use internal motor representations of object manipulation. These results are discussed in terms of motoric and non-motoric perceptual processes and the proposal of an additional ventro-dorsal sub-stream within the dorsal and ventral visual pathways model
