| Sumario: | The explosive growth over the last two decades of neuroscience, cognitive science, and "consciousness studies" as generally conceived, remains as yet unaccompanied by a corresponding development in the establishment of an explicitly semiotic understanding of how the relations of sign exchange at the neuronal level function in the larger network of psychologically accessible sign exchange. This article attempts a preliminary foray into the establishment of just such a neurosemiotic. It takes, as its test case and as its point of departure, recent discoveries from the neurobiological research on viuso-motor transformations and on the widespread cortical phenomena of selectively tuned, single-neuron response to argue for a vision of "intersubjectivity" whereby the ens rationis arising as a function of the neuronal semiosphere may be abstracted, constructed, and shared mutually across agents. Nagu üldteada, pole närviteaduse, kognitiivse teaduse ja "teadvusuuringute" plahvatusliku arenguga kahe viimase kümnendi jooksul siiski tänini kaasnenud samasugust arengut nende valdkondade poolt uuritavate nähtuste semiootilisel mÕistmisel. Senini pole teada, kuidas märgiseosed neuronite tasandil saavad toimida psühholoogiliselt ligipääsetavate märgiseoste laiemas vÕrgustikus. Käesolev artikkel püüab olla esialgseks lähenemiseks just säärasele neurosemiootikale. Oma proovimaterjali ja lähtepunktina kasutame viimaseid avastusi neurobioloogiliste uuringute vallas: visuaal-motoorseid üleminekuid ja üksikneuronite valikuliselt häälestatud vastusreaktsioone, mis on laialtlevinud kortikaalseks nähtuseks. Sellelt lähtekohalt väidetakse "intersubjektiivsuse" kohta, et ens rationis ilmub kui neuraalse semiosfääri funktsioon, mis saab abstraheeruda, konstrueeruda ja toimurite vahel vastastikku jaotuda. |
