In a companion study (Carnicella et al., 2005), we showed that the muscarinic antagonist atropine, when administered after extensive training during both conditioning and testing, affected neither cued nor contextual fear memories when both of them did not compete for

CD-1 mice were trained in a classically conditioned emotional response paradigm and tested 24 hr later. Exposure to an open field 0 or 1, but not 3 hr after training retroactively interfered with retention of the conditioned emotional response. The
The present study was undertaken to examine the effects of different muscarinic receptor agonists on glutamate and GABA concentrations in the medial prefrontal cortex of the rat. In vivo perfusions were made in the conscious rat using a concentric push-pull
Immobility during forced swimming or after mild footshock (1 mA for 2 sec) was observed in five groups of rats. The Flinders Sensitive Line (FSL) of rats, known to be more sensitive to cholinergic agonists, exhibited the greatest degree of
An in vivo pharmacological study on muscarinic receptor subtypes regulating cholinergic neurotransmission in rat striatum.
