In order to study the effect of A/[beta] on
cholinergically induced theta oscillatory activity, we first generated such activity by applying carbachol [20 [micro]M] to the perfusion system [82].
Psycho-physiological reactivity in asthmatic children: A
cholinergically mediated confluence of pathways.
Although 5-[HT.sub.4] receptors are involved in
cholinergically mediated contraction in the guinea pig gut, the lack of data identifying the 5-[HT.sub.4] receptor in humans makes their physiological and medical significance, if any, unclear.
The rationale for using anticholinergic agents rests on the knowledge that, in healthy persons, bronchomotor tone is predominantly
cholinergically mediated through the parasympathetic nervous system.
