More Co2 = less brains?

what you are describing is the typical drowsiness that overcomes people in
overcrowded lecture-halls. Due to high CO2 concentrations gas exchange
in the lung gets inhibited and the brain cannot get enough oxygen to
function fully. But as far as I know the critical parameter is CO2
concentration, since it binds tighter to the hemoglobin in the blood than
O2 and with higher external CO2 it does not dissociate as readily as it
does normally. For further information se any physiology textbook.

All the best, Leo
