Evidence suggests homologies in parietofrontal circuits involved in object prehension among humans and monkeys. Likewise, tool use is known to induce functional reorganization of their visuotactile limb representations. Yet, humans are the only species for whom tool use is a defining and universal characteristic. Why? Comparative studies of chimpanzee tool use indicate that critical differences are likely to be found in mechanisms involved in causal reasoning rather than those implementing… Expand

Neurological Specializations for Manual Gesture and Tool Use in Humans
Primates possess a unique ability to manipulate their environments through dexterous use of the hands. Neuroantomical and physiological data from Old and New World monkeys suggest the existence ofExpand
The neural bases of complex tool use in humans
The behaviors involved in complex human tool use cut across boundaries traditionally drawn between social, cognitive, perceptual and motor processes. Longstanding neuropsychological evidence suggestsExpand
The Representation of Tool Use in Humans and Monkeys: Common and Uniquely Human Features
Though other species of primates also use tools, humans appear unique in their capacity to understand the causal relationship between tools and the result of their use. In a comparative fMRI study,Expand
From action to language: comparative perspectives on primate tool use, gesture and the evolution of human language
The papers in this Special Issue examine tool use and manual gestures in primates as a window on the evolution of the human capacity for language. Neurophysiological research has supported theExpand
Monkey See, Monkey Plan, Monkey Do
The way human adults grasp objects is typically influenced by their knowledge of what they intend to do with the objects. This influence is reflected in the end-state comfort effect: Actors adoptExpand

Determining the brain adaptations that underlie complex tool-use skills is an important component in understanding the physiological bases of human material culture. It is argued here that the waysExpand
Perception meets action: fMRI and behavioural investigations of human tool use
Tool use is essential and culturally universal to human life, common to huntergatherer and modern advanced societies alike. Although the neuroscience of simpler visuomotor behaviours like reachingExpand
The Neuroscience of Human Tool Use
In this chapter we review evidence for two complementary theories of the neural organization of human tool use. First, it is likely that experience-dependent modifications to preexisting neuralExpand

An influential theory suggests that the dorsal (occipito-parietal) visual stream computes representations of objects for purposes of guiding actions (determining 'how') independently of ventralExpand

Coding of modified body schema during tool use by macaque postcentral neurones.
TLDR
Macaque monkeys are trained to retrieve distant objects using a rake, and neuronal activity was recorded in the caudal postcentral gyrus where the somatosensory and visual signals converge, and a large number of bimodal neurones appeared to code the schema of the hand. Expand
Motor and cognitive functions of the ventral premotor cortex
TLDR
Preliminary evidence suggests that the ventral part of the lateralPremotor cortex in humans may correspond to monkey area F4, and a tentative map of the human lateral premotor areas founded on the reviewed evidence is presented. Expand
Origins of knowledge.
TLDR
These experiments suggest that cognition develops concurrently with perception and action and that development leads to the enrichment of conceptions around an unchanging core. Expand
Functional Brain Mapping of Monkey Tool Use
When using a tool, we can perceive a psychological association between the tool and the body parts-the tool is incorporated into our "body-image." During tool use, visual response properties ofExpand
The Cortical Motor System
TLDR
It is submitted that generating internal representations of actions is central to cortical motor function and external contingencies and motivational factors determine then whether these action representations are transformed into actual actions. Expand
Selective Activation of a Parietofrontal Circuit during Implicitly Imagined Prehension
TLDR
The results show that in contrast to preparation of overt actions, preparation of either hand for covert movement simulation activates a large network of motor-related areas located primarily within the left cerebral and right cerebellar hemispheres, which concludes that motor imagery involves action-specific motor representations computed in parietofrontal circuits.

Intentional maps in posterior parietal cortex.
The posterior parietal cortex (PPC), historically believed to be a sensory structure, is now viewed as an area important for sensory-motor integration. Among its functions is the forming ofExpand

An information-processing model is outlined that predicts that performance on non-routine tasks can be impaired independently of performance on routine tasks. The model is related to views on frontalExpand
"What" and "how": evidence for the dissociation of object knowledge and mechanical problem-solving skills in the human brain.
TLDR
It is suggested that sensory inputs to a parietal "how" system can trigger the use of objects without reference to object-specific conceptual knowledge, as well as the hypothesis of a separate action-semantic system. Expand
Activation in the Ipsilateral Posterior Parietal Cortex during Tool Use: A PET Study
TLDR
The results suggest that the ipsilateral posterior parietal cortex was recruited during the tool-use tasks to integrate visuosomatosensory information. Expand
