... induces the experience of visual images during perception and mental imagery, 2) interferes with or facilitates perception and/or imagery in concurrent and dual task conditions, 3) correlates with self-reports such as vividness ratings, and 4) red...
The perception of patterns not resulting from viewing external objects but stimulated by cranial electrodes with pulse currents within the electroencephalographic frequency range ('phosphenes') has been investigated in earlier work. The experiments d...
