Dynamic Eeg Changes During Cigarette Smoking
Abstract
Outlines a study done on 20 human subjects, measuring delta, theta, alpha, beta and peak alpha frequency. Finds, postsmoking, decrease in delta and theta power, increase in alpha power and increase in alpha frequency. Reports effects emerging after fourth puff. Notes that this EEG profile differs from that of amphetamines of methylphenidate type psychostimulants.

Knott, V.J.,
Dynamic EEG changes during cigarette smoking,
Neuropsychobiology 19: 54-60 (1988)
subjects: 20 humans
smoking or sham-smoking own brand, apparently not smoke-deprived
measure, before, during, and after smoking: delta (1 to 4 Hz), theta (4 to 7 Hz), alpha (8 to 13
Hz),
beta (13 to 20 Hz), and peak alpha frequency
postsmoking: decrease in delta and theta power, increase in alpha power and increase ... alpha
frequency
effects transient 1 st half of 3 min postsmoking, theta no longer significant
2nd half of 3 min similar to first half
puff x puff - effects generally emerged after 4th puff
no effects due to anticipatory puffing
during puffing, there was a decrease in delta power (sensory-related)?
postchanges in delta apparent
20 to 25 s postpuffing
This EEG profile differs from that of amphetamines of methylphenidate type psychostimulants.
