| There are flower-like forms, too, which may be literal blooms, or imaginings of stars, or phosphenes, those optical flashes seen during trances. |
| Visual effects like phosphenes or lightnings when I opened my eyes were also very light. |
| These early studies were limited by problems such as flickering phosphenes and interactions between phosphenes. |
| Compared with normal subjects, people with the synesthesia required only one-third the stimulation to experience phosphenes, or transient flashes of light. |
| The effects include fibrillation, electroshock, induction of visual phosphenes, and initiation of impulses in nerve and muscle cells. |
| Dr. Malotki's latest focus is on designs called phosphenes, which are as fundamental to art as time is to language. |
