Document Summary

Fundamental operating characteristics of the dorsal and ventral processing model. In the 150ms lights off had more errors. 2: between 75 and 150 is the minimal processing time to modify an online action through visual feedback, reaction to an unexpected change, online (only for dynamic) feedback can occur in less than 75ms, extrageniculate pathway. Subjects maintained static balance: visual information is a source of afferent information controlling balance. Ignore proprioceptive and somatic system and focus on the visual system for balance. Proprioception: feedback resource contributed to by various systems. Sensitive to each directional planes: however if the head is maintained in that position, cilia stop firing. Semicircular detect rotations: horizontal canal - rotation in the vertical axis (spinning, anterior and posterior canal in the saggital plane (nodding) and in the frontal plane (completing a somersault) Otolith organs detect changes in gravity and acceleration: utricle detect change in horizontal movement and linear acceleration (important for eye movements) - walking.
