Description

Apart from having big brain primates are also distinctly visual animals. For better visual perception the eyes of the mammals project forwards thus enabling binocular vision, two physiologically distinct pathways, (parvocellular attending to the detail and colour, and magnocellular involved in movement) within the layered subcortical lateral geniculate nucleus, an excellent binocular integration, and high visual acuity have developed and, later in evolution, higher nonV1 visual regions have emerged with a numerous cortical regions interacting in a complex arrangement of progressively more elaborate and more focused analysis of visual information. Relatively recently, in early Paleolithic, these hierarchically organized visual cortices start interacting with the now mature prefrontal cortex and - while remaining predominantly visual - Homo sapiens sapiens was now able to fully express his human creativity, arts, symbolism, religion, science and plan more coherent and formally organized social life.

Predavanje je zelo zanimivo in privlaćno je kot nova oblika umetnosti , novi vidik in nova pot . Zanimivo je verjeti da je nedoumljivo doumljivo .
