In a study of working memory, the performance of rats under titrating-delayednonmatching-to-
position (TDNMTP) procedures was examined. Overall accuracy and the number of trials …

A matching-to-position task was used to investigate the effects of numerous variables on
spatial working memory in the rat. The primary interest was whether implementing the …

The effects of scopolamine and methyl scopolamine on working memory processes were
investigated in a paired trial, go-no go delayed response procedure in which rats initiated …

Operant delayed non-matching-to-position (DNMTP) and delayed matching-to-position
(DMTP) have become standard techniques to investigate drug effects on short-term memory …

Drugs of abuse produce amnestic effects in humans and laboratory animals in a variety of
tasks. Generally, only a few compounds have been examined in any particular procedure. It …

The effects of fixed-ratio (FR) size, scopolamine, and the interactions between FR size and
scopolamine were investigated in male F344 rats on working memory as assessed by …

The effects of a muscarinic antagonist (scopolamine), a muscarinic agonist (oxotremorine),
an agonist at the N-methyl-D-aspartate receptor site (D-cycloserine), and a GABA a …

Previous studies have shown that scopolamine treatment impairs working memory
performance in rats as measured on the radial maze, but it is not clear what cognitive …

The effects of scopolamine hydrobromide on performance in uninterrupted and delayed
radial maze trials were studied in the rat. In addition to defining errors as incorrect arm …

Rats were trained to run in a spatial, radial maze for sucrose reward using a procedure that
permitted determination of two memory functions [working memory (WM) and reference …
