Caro Oscar
Purtroppo, basarsi su di un articolo tratto da "La Repubblica" porta a dire stupidaggini... Puoi leggerti questo articolo: EBSCOhost: Opinion: How do you feel? Interoception: the sense of the physiological con... del quale ti riporto una parte significativa:
So, the evidence indicates that, in primates,the dorsal insular cortex contains a sensory representation of the small-diameter afferent
activity that relates to the physiological condition of the entire body. This cortical region seems to constitute a primary interoceptive image of homeostatic afferents. Embedded in the interoceptive cortex are the cortical representations of several highly resolved, distinct sensations, including temperature, pain, itch, muscular and visceral sensations, sensual touch and other feelings from the body. The importance of the interoceptive cortex for physical well-being is underscored by its clear
delimitation in the monkey by
in situ hybridization labelling for the mRNA of receptors for corticotropin-releasing factor, which is thought by many to be a definitive indicator of an association with homeostatic stress.
Notably, the absence of this direct interoceptive representation in sub-primates implies that they cannot experience feelings from the body in the same way that humans do. In humans, lesions of the dorsal insula interrupt these feelings, disrupt homeostatic processing and cause permanent loss of discriminative thermal sensation. By contrast, in cats
that have been trained on a high-resolution thermosensory discrimination task, lesions of the rudimentary thalamocortical lamina I relay cause only a weak, transient behavioural deficit, whereas a spinal lesion of the ascending lamina I axons causes permanent disruption.
Se vuoi la traduzione, chiedi. Se vuoi tradurlo da solo, fai. Ma traduci, non tradire. Almeno stavolta.
Resto in attesa di potermi andare a sedere sull'Everest....
Buona vita
