Neurobiology of “Umwelt”
Inserisco un brano dall'introduzione del testo di A. Berthoz e Y. Christen (edts) - Neurobiology of “Umwelt”. How Living Beings Perceive the World - Springer 2009. At the beginning of the 20th century, German biologist Jakob von Uexkull created the concept of Umwelt to denote the environment as experienced by a subject. This concept of environment differs from the idea of passive surroundings and is defined not just by physical surroundings, but rather is a “subjective universe”, a space weighted with meaning. Based on this perspective, a living organism, no matter how basic (such as the tick studied by von Uexkull), creates its own universe when it interacts with the world and as this same time the organism reshapes it. Today, neuroscience provides a new way to look at the brain’s capability to create a representation of the world. At the same time, behavioral specialists are demonstrating that animals have a richer mental universe than previously known. Philosophical reflection thu
