Tests of object recognition memory, or the judgment of the prior occurrence of an object,
have made substantial contributions to our understanding of the nature and neurobiological …

The muscarinic cholinergic system constitutes an important part of the neuronal circuitry that
modulates normal cognition. Muscarinic receptor antagonists are well known to produce or …

Damage to perirhinal cortex (PRh) impairs object recognition memory in humans, monkeys,
and rats when tested in tasks such as delayed nonmatching to sample, visual paired …

Crocus sativus L. is a plant cultivated in various parts of the world. Crocins are among the
active components of Crocus sativus L. The present study was designed to investigate in the …

Among the five different muscarinic receptors that have been cloned and characterized, M2
and M4 receptors are localized both post-and presynaptically and are believed to have a …

The perirhinal cortex of the temporal lobe has a crucial role in object recognition memory.
Cholinergic transmission within perirhinal cortex also seems to be important for this function …

Abstract Antagonists at serotonin type 6 (5-HT 6) receptors show activity in models of
learning and memory. Although the underlying mechanism (s) are not well understood …

The effects of ginsenosides Rg 3 (R), Rg 3 (S) and Rg 5/Rk 1 (a mixture of Rg 5 and Rk 1, 1:
1, w/w), which are components isolated from processed Panax ginseng CA Meyer …

The development of small molecule modulators of NO/cGMP signaling for use in the CNS
has lagged far behind the use of such clinical agents in the periphery, despite the central …

The novel object recognition task (NORT) assesses recognition memory in animals. It is a
non-rewarded paradigm that it is based on spontaneous exploratory behavior in rodents …
