The cortical thickness of the area PF of the left inferior parietal cortex mediates technical-reasoning skills

Scientific Reports, Journal Year: 2022, Volume and Issue: 12(1)

Published: July 12, 2022

Abstract Most recent research highlights how a specific form of causal understanding, namely technical reasoning, may support the increasing complexity tools and techniques developed by humans over generations, i.e., cumulative technological culture (CTC). Thus, investigating neurocognitive foundations reasoning is essential to comprehend emergence CTC in our lineage. Whereas functional neuroimaging evidence started highlight critical role area PF left inferior parietal cortex (IPC) no studies explored links between structural characteristics such brain region skills. Therefore, this study, we assessed participants’ technical-reasoning performance using two ad-hoc psycho-technical tests; then, extracted from 3 T T1-weighted magnetic-resonance images cortical thickness (i.e., volume-related measure which associated with cognitive as reflecting size, density, arrangement cells region) all IPC regions for both hemispheres. We found that predicts performance. Crucially, reported correlations other regions, possibly suggesting specificity generating knowledge. discuss these findings an evolutionary perspective, speculating about evolution lobes have supported

Simultaneous real-time EEG-fMRI neurofeedback: A systematic review

Frontiers in Human Neuroscience, Journal Year: 2023, Volume and Issue: 17

Published: March 31, 2023

Neurofeedback (NF) is a biofeedback technique that teaches individuals self-control of brain functions by measuring activations and providing an online feedback signal to modify emotional, cognitive, behavioral functions. NF approaches typically rely on single modality, such as electroencephalography (EEG-NF) or imaging technique, functional magnetic resonance (fMRI-NF). The introduction simultaneous EEG-fMRI tools has opened up the possibility combining high temporal resolution EEG with spatial fMRI, thereby increasing accuracy NF. However, only few studies have actively combined both techniques. In this study, we conducted systematic review EEG-fMRI-NF (N = 17) identify potential effectiveness non-invasive treatment for neurological conditions. revealed lack homogeneity among studies, including sample sizes, acquisition methods in terms simultaneity two procedures (unimodal EEG-NF fMRI-NF), therapeutic targets field, number sessions. Indeed, because most are based session NF, it difficult draw any conclusions regarding efficacy Therefore, further research needed fully understand non-clinical clinical EEG-fMRI-NF.

Cultural attraction in pottery practice: Group-specific shape transformations by potters from three communities

PNAS Nexus, Journal Year: 2024, Volume and Issue: 3(2)

Abstract Pottery is a quintessential indicator of human cultural dynamics. Cultural alignment behavioral repertoires and artifacts has been considered to rest upon two distinct dynamics: selective transmission information culture-specific biased transformation. In cross-cultural field experiment, we tested whether community-specific morphological features ceramic vessels would arise when the same unfamiliar shapes were reproduced by professional potters from three different communities who threw using wheels. We analyzed details underlying morphogenesis development in wheel throwing. When expert practice instructed faithfully reproduce common model that not parts daily repertoires, morphometric variation final shape was random; rather, produced with more among than within communities, indicating presence deviations vessels. Furthermore, this found both process morphogenesis; there morphogenetic path communities. These results suggest reliably nonrandomly diverge The present study provides empirical evidence collective can habits fashioning clay.

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.

At heart theory are concepts causal chains, attractors, factors attraction. can be used pluralistic evolution by articulating these three concepts. In particular, several empirical case studies different domains have successfully relate phenomena (attractors) their causes (factors attraction).
