Weak associations between electrocortical changes and respiratory rate changes during wakefulness and non-REM sleep. (A) During wakefulness and non-REM sleep, there was no changes in respiratory rate, despite changes in electrocortical powers. (B) Weak correlations between respiratory rate and electrocortical changes were observed following control injection. Dia, diaphragm.
