We trained Japanese macaque monkeys to use tools, an advanced cognitive function monkeys do not exhibit in the wild, and then examined their brains for signs of modification. Following tool-use training, we observed neurophysiological, molecular genetic and morphological changes within the monkey brain. Despite being ‘artificially’ induced, these novel behaviours and neural connectivity patterns reveal overlap with those of humans. Thus, they may provide us with a novel experimental platform…

Triadic (ecological, neural, cognitive) niche construction: a scenario of human brain evolution extrapolating tool use and language from the control of reaching actions

A speculative argument about the origins of the brain's neurobiological mechanisms is advanced, as an extension (with wider scope) of the evolutionary principles of adaptive function in the animal nervous system.
Rethinking Phylogeny and Ontogeny in Hominin Brain Evolution
It is argued that the combination of these evolutionary trends underpins the complexity of human behaviour, as the neural circuits involved in cognitive mechanisms such as the mirror neuron system mature only slowly, and require considerable socially-scaffolded experience to develop to their full potential.
Differences in Neural Activation for Object-Directed Grasping in Chimpanzees and Humans
Chimpanzee activation showed a prefrontal bias, including significantly more activity in ventrolateral prefrontal cortex, whereas human activation was more evenly distributed across more posterior regions, suggesting that the evolution of tool use, social learning, and cumulative culture may have involved modifications of frontoparietal interactions.
Superior pattern processing is the essence of the evolved human brain
Humans have long pondered the nature of their mind/brain and, particularly why its capacities for reasoning, communication and abstract thought are far superior to other species, including closely
The role of play objects and object play in human cognitive evolution and innovation
The model suggests that salient material culture innovation may occur or be primed in a late childhood or adolescence sweet spot when cognitive and physical abilities are sufficiently mature but before the full onset of the concerns and costs associated with reproduction.

It is concluded that human tool use still marks a major cognitive discontinuity between us and the authors' closest relatives and the evolution of human technologies.
Early Tool-Making and the Evolution of Human Memory Systems in the Brain
Outlines about ancient Paleolithic artifacts and early Homo (2-1 Ma) skeletons precede considerations about cognitive versatility and developmental limitations of evolving brains, whereby haptic working memory and propensity for habitual procedural memory evolved alongside explicit and implicit mental perspectives.
Developmental niche construction
The transmission of culturally relevant information, how the human mind is a symbol-generating and artefact-devising system, and how these processes are bi-directional are discussed, with infants and children both being directed, and directing, their own development.

Perception meets action: fMRI and behavioural investigations of human tool use
Grasping actions typical of how tools are normally grasped during use were found to preferentially activate occipitotemporal areas, including areas specialized for visual object recognition, which is likely to represent an important source of inputs to visuomotor areas as to learned conceptual knowledge of tool use.

The brain is understood to the extent that humanoid robots solve tasks typically solved by the human brain by essentially the same principles, and a new experimental paradigm, manipulative neuroscience, is proposed to overcome this difficulty and allow us to prove cause-and-effect relationships even at the system level.
Rapid learning of sequential tool use by macaque monkeys
Acquisition and development of monkey tool-use: behavioral and kinematic analyses.
Four Japanese macaques trained in the use of a T-shaped rake developed the level of skill required for efficient retrieval and attempted to use unfamiliar objects which were similar to the original tool in shape, but not spherical or ring-shaped objects, to rake in the food.

Anatomical Traces of Vocabulary Acquisition in the Adolescent Brain
Brain imaging, detailed behavioral analyses, and white matter tractography in English-speaking monolingual adolescents are combined to show that a critical linguistic prerequisite (namely, knowledge of vocabulary) is proportionately related to relative gray matter density in bilateral posterior supramarginal gyri.
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 of

Does the chimpanzee have a theory of mind?
Abstract An individual has a theory of mind if he imputes mental states to himself and others. A system of inferences of this kind is properly viewed as a theory because such states are not directly
Neuroplasticity: Changes in grey matter induced by training
This discovery of a stimulus-dependent alteration in the brain's macroscopic structure contradicts the traditionally held view that cortical plasticity is associated with functional rather than anatomical changes.
