4. Ha knew no present Jeans of producing confusien, or convulsion with unconscicusness, in every subject by means of interrupted light alone (it is well knowm that some subjects are that sensitive). He has experimentally endured various intensities and frequencies for three hours continuously without ill effects.

5. He believed that any subject could be convulsed by flicker, provided he were first sensitized by metrasol or an equivalent given intravenously. Different frequencies have to te tried, running through a range of say 13 to 18 flashes per second; intensity, about lo0 fcotcandles. Most subjects seem most sensitive to l6 flashes per second; a few, to 9. Forty seconds exposure often suffice; a few minutes at nost.

6. Instead of metrazol, he routinely uses Azozol (Boots Pharmaceutical, New York) which is stronger.

Not mowm, whether this or enobher 1 sensi drus could be safely corbined with an anti-emetic drug, so as to make 三 capable of sensiticing more subjects.

3. He did not kmow whether encugh of a volatile arphetarin or other dmg could be given by inhalasion, to sensitise a majority of subjects to flicker-conzulsion (or confusion),

9. If the subject yere to be surrounded by a wall of a plastis substance like lucite, a strcng encugh Lignt behind this would be effective through-it, regardless of the subject's direotion of gase (closed eyelids do not protect).

10. He had no experience of any anti-conrlsive irug peculiarly prophylactic against photogenis seisures. Numerous vell-kowm anticonvulsants could be tried.

1l. He thought that interrupted sound, being less effective than Combining sound with light seemed to hin to add more corplication than it offered zaineither toward making subject more sensitive, or making more subjects sensitive,

12. Smell, continucus or interrupted, seemed to have been far less experimented with; such experiments as'the literature offered had been unpromising in his opinion.

13. 's interest has seemed sufficient, equally with his status as an EEG authority, for me to offer the suggestion that the Agency consider his use as a consultant.
