“…To examine this, participants completed either the hand or foot variant of the semantic generation task from Esopenko et al (2008, 2011), with the same stimuli presented in both picture and word formats to directly compare whether there are differences in processing in the PFN dependent upon picture versus word format. Furthermore, we sought to examine whether the semantic generation and motor localization tasks showed a shared network of activation in the PFN.…”

The theory of embodied cognition postulates that the brain represents semantic knowledge as a function of the interaction between the body and the environment. The goal of our research was to provide a neuroanatomical examination of embodied cognition using action-related pictures and words. We used functional magnetic resonance imaging (fMRI) to examine whether there were shared and/or unique regions of activation between an ecologically valid semantic generation task and a motor task in the parietal-frontocentral network (PFN), as a function of stimulus format (pictures versus words) for two stimulus types (hand and foot). Unlike other methods for neuroimaging analyses involving subtractive logic or conjoint analyses, this method first isolates shared and unique regions of activation within-participants before generating an averaged map. The results demonstrated shared activation between the semantic generation and motor tasks, which was organized somatotopically in the PFN, as well as unique activation for the semantic generation tasks in proximity to the hand or foot motor cortex. We also found unique and shared regions of activation in the PFN as a function of stimulus format (pictures versus words). These results further elucidate embodied cognition in that they show that brain regions activated during actual motor movements were also activated when an individual verbally generates action-related semantic information. Disembodied cognition theories and limitations are also discussed.

“…For example, Moosa et al (2013) found that younger age at epilepsy onset correlated with poor reading skills but not with spoken language skills. Detailed study of the linguistic ability of two clinical cases suggests that the right hemisphere is critical for normal picture naming, whereas the left hemisphere is critical for normal semantic generation of action-related knowledge (Esopenko et al, 2011). An fMRI research on a 14-year-old adolescent who underwent a left hemispherectomy at the age of 2.5 years suggest that his solitary right hemisphere followed a left-like blueprint of the linguistic network, but with a stronger frontal recruitment (Danelli et al, 2013).…”

Language is a specifically human mental function, although some neurobiological adaptations associated with communication can be found in other primates, in other mammalian orders, and even in other kinds of animals (evolutionary trend). Exposure to language is necessary for its acquisition (culture), there are specific alleles of some genes for human language (gene), and the brain circuits for language are mainly lateralized towards the left hemisphere (brain lateralization). However, some data suggest that the crucial factor for human verbal language, which originates in childhood in both, ontogeny and phylogeny, must be of motivational nature, and have at least the same importance as other genetic, brain or cultural factors. So, this article proposes that language was promoted by the building of love, and that it was maintained by hominid women as proto-language during some hundreds of thousands years through the maternal-filial interaction, until the first permanent settlements of the current human species, between 40,000-10,000 years ago. Also, that it was then when the woman transmitted speech to the man (it is further suggested that this may have been the Original Sin of the biblical Genesis), signalizing this transmission with the beginning of the symbolic thought, thus promoting the first artistic displays, like sculptures, painting or music, which were associated with the expansion of love and speech to the relationship between the sexes, with the consequent diversification of languages, mainly in the last 10,000 to 5,000 years. Love caused and causes human speech in both, phylogeny and ontogeny.

This paper investigates experiences of resilience in the context of individuals suffering from disability as a result of severe intractable seizure disorder and consequent hemispherectomy, a surgical procedure in which part or all of either the left or right cerebral hemisphere is removed. Two adults who underwent childhood hemispherectomies-one left and one right-are the focus of this study. Previous research has extensively detailed the clinical outcomes of this neurological procedure, yet the actual day-to-day experiences of individuals living post-hemispherectomy remains unexplored. Utilizing open-ended, qualitative, and narrative techniques from a phenomenology of performativity perspective, the authors question how each individual's experiences of daily living are invariably acts of resilience, involving several different strategies that are somewhat unique to each. Rather than working as an adjective or noun signifying certain environmental or individual attributes, this paper proposes that "resilience" is best conceptualized as the individualized intentional actions which disabled, distraught, or at risk individuals perform in contextually relevant and idiosyncratic ways as they navigate health and well-being within their local social and moral worlds.
