Exploratory Study on the Generation of Visual Signs and Meaning Processing through Neuro‐semiotics
Jo, Chang-yeon
This paper addresses the question of how visual signs and their meanings are processed from a neuro-semiotic viewpoint. The neuro-semiotic method refers to a sort of applied semiotics, which complements and extends cognitive semiotics from perspectives on brain and cognitive science.
According to the study results, it can be concluded that the process from retina to optic chiasm is characteristic of quali and sin, being regarded that an object really exists on the outside and signs reflect and project the nature and properties of the object. Moreover, this process incorporates the nature of legi, membrane potential produced on the base of special rules.
Visual information reached at the lateral geniculate nucleus being projected to the first visual cortex in a realistic and causal way acquires the property of an index. Nerve cells in the superior colliculi refer to objects and interpret them, reacting particularly to moving objects and their direction, demonstrating the traits of a dicent. The first visual cortex(V1), which deals with visual information syntagmatically, is characteristic of an argument, in that the V1 makes inferential claims to the interpretant. The area dispersed throughout the temporal lobe deals with form, colour and figures at the level of the conscience, while they are represented similar to prior information produced in former brain areas, generate a sort of icon. If the generated sign belongs to an icon, but its nature is represented strongly on the basis of a similarity, the sign is marked with an image. The image comes in the form of a diagram in the case of a strong structural similarity to the icon, while it is a
characteristic of a metaphor in cases where the icon is represented by an associative similarity.
The parietal lobe deals with position movement and three-dimensional space unconsciously, and generates a nature of signs such as rhema, interpreting a certain amount of semantically nondetermined visual information. All of these processes in the long run generate visual signs, characteristically regarded as symbols, because symbol-signs are formed with associations of general concepts able to refer to outside objects while simultaneously interpreting them.
