Nicolelis' team reported in 2003 that the researchers had implanted electrodes in the frontal and parietal lobes of the brains of two female rhesus monkeys that used a joystick to control a cursor on a computer screen. Additional research suggests that changes like those occurring in the frontal lobes occur in the parietal lobes, which are involved in the processing of sensory information, in addition to other functions; in the occipital lobes, which are involved in the processing of visual information; and in the temporal lobes, which are critically involved in memory formation as well as visual and auditory processing (Geidd et al. Pressure on the sensory cortex or parietal lobes can lead to a loss of the ability to process complex sensory input and can result in astereognosis, agraphesthesia, or difficulties with tactile localization and two-point discrimination. |
