| Outline of Final Research Achievements |
Psychophysical adaptation will affect the effectiveness of Brain-Machine interface which send artificial sensory input to the brain. Here we tried to evaluate and manipulate the adaptation in suprachoroidal-transretinal stimulation-type retinal prosthesis with electrophysiological method. The decline of evoked response by repetitive retinal stimulation was able to be recorded in cat visual cortex with multichannel electro-corticogram. Simultaneous stimulation to other cortical area which we tested could not change the decline of evoked response. Strategy for preventing adaptation was shown to be more investigated.
