Our propensity to materiality, which consists in using, making, creating, and passing on technologies, has enabled us shape the physical world according our ends. To explain this proclivity, scientists have calibrated their lens either low-level skills such as motor cognition or high-level language social cognition. Yet, little been said about intermediate-level cognitive processes that are directly involved mastering is, technical We aim focus intermediate level for providing new insights into neurocognitive bases of human materiality.

Abstract Cumulative technological culture is defined as the increase in efficiency and complexity of tools techniques over generations. While role social cognitive skills cultural transmission has been long acknowledged, recent accounts have emphasized that non-social such technical reasoning, a form causal reasoning aimed at understanding physical world, are also work during content. Here we contribute to this double process approach by reporting an fMRI study about neurocognitive origins learning. Participants were shown videos depicting tool-making episodes three social-learning conditions: Reverse engineering, Observation Teaching. Our results showed technical-reasoning network, centred around Area PF left inferior parietal cortex, was preferentially activated when watching episodes. Additionally, teaching component related activation right middle temporal gyrus. We propose heart our cognition improve learner’s helping them concentrate on important parts technology. Thus, both social-cognitive may play key evolution technologies.

Tool-use skills represent a significant cognitive leap in human evolution, playing crucial role the emergence of complex technologies. Yet, neural mechanisms underlying such capabilities are still debated. Here we explore with fMRI functional brain networks involved tool-related action understanding. Participants viewed images depicting action-consistent (e.g., nail-hammer) and action-inconsistent scarf-hammer) object-tool pairs, under three conditions: semantic (recognizing tools previously seen pairs), mechanical (assessing usability control (looking at pairs without explicit tasks). During observation task-based left-brain connectivity differed within conditions. Compared to control, both conditions exhibited co-activations dorsal (precuneus) ventro-dorsal (inferior frontal gyrus) regions. However, condition recruited medial posterior temporal areas, whereas engaged inferior parietal Also, when distinguishing from an extensive frontotemporal circuit was activated. These findings support recent accounts that view understanding as combined product knowledge. Furthermore, they emphasize how left anterior lobes might be considered hubs for cross-modal integration physical conceptual knowledge, respectively.

Limb apraxia is a motor disorder frequently observed following stroke. Apraxic deficits are classically assessed with four tasks: tool use, pantomime of imitation, and gesture understanding. These tasks supported by several cognitive processes represented in left-lateralized brain network including inferior frontal gyrus, parietal lobe (IPL), lateral occipito-temporal cortex (LOTC). For the past twenty years, voxel-wise lesion symptom mapping (VLSM) studies have been used to unravel neural correlates associated apraxia, but none them has proposed comprehensive view topic. In present work, we fill this gap performing systematic Anatomic Likelihood Estimation meta-analysis VLSM which included traditionally assess apraxia. We found that IPL was crucial for all tasks. Moreover, lesions within LOTC were more imitation than use or pantomime, confirming its important role higher visual processing. Our results questioned traditional neurocognitive models on may clinical implications.

Brain evolution is a key topic in evolutionary anthropology. Unfortunately, this sense the fossil record can usually support limited anatomical and behavioral inferences. Nonetheless, information from species is, any case, particularly valuable, because it represents only direct proof of cerebral changes throughout human phylogeny.

A limitation the literature is partial uptake progress characterizing disease-related features, particularly negative symptoms (NS) and cognitive impairment (CI).

Children with autism spectrum disorder (ASD) have difficulties in gestural communication during social interactions. However, the neural mechanisms involved naturalistic remain poorly understood. In this study, cortical activation patterns associated were examined thirty-two children and without ASD (mean age: 11.0 years, SE: 0.6 years). Functional near-infrared spectroscopy (fNIRS) was used to record while produced, observed, or imitated communicative gestures. demonstrated more spatial temporal errors when performing imitating Although both typically developing (TD) showed left-lateralized gesture production, hyperactivation middle/inferior frontal gyrus (MIFG) observation imitation, hypoactivation middle/superior (MSTG) production compared their TD peers. More importantly, exhibited greater MSTG imitation than suggesting that could be an effective intervention strategy engage regions crucial for processing producing Our study provides valuable insights into underlying ASD, also identifying potential neurobiomarkers serve as objective measures evaluating effectiveness ASD.

Children with autism spectrum disorder (ASD) have difficulties tool use and pantomime actions. The current study utilized functional near-infrared spectroscopy (fNIRS) to examine the neural mechanisms underlying these gestural difficulties. Thirty-one children without ASD (age (mean ± SE) = 11.0 0.6) completed a naturalistic peg-hammering task using an actual hammer (hammer condition), pantomiming hammering actions (pantomime performing meaningless similar joint motions (meaningless condition). exhibited poor praxis performance (praxis error: TD 17.9 1.7; 27.0 2.6, p < 0.01), which was significantly correlated their cortical activation (R 0.257 0.543). Both groups showed left-lateralized activation, but demonstrated more bilateral during all conditions. Compared typically developing children, hyperactivation of inferior parietal lobe hypoactivation middle/inferior frontal middle/superior temporal regions. Our findings indicate intact technical reasoning (typical left-IPL activation) atypical visuospatial proprioceptive processing (hyperactivation right IPL) in ASD. These results important implications for clinicians researchers, who should focus on facilitating/reducing burden Additionally, fNIRS-related biomarkers could be used early identification through object play/tool effects following gesture-based interventions.
