Rats with electrolytic lesions of the medial septum or ibotenic acid lesions of the nucleus
basalis magnocellularis (NBM) were tested in an order memory task for an 8-item list of …

A total of 162 male Sprague-Dawley albino rats were tested both pre-and postoperatively
either on a DRL 20-sec schedule (Exp I) or for spontaneous alternation (Exp II). Selective …

This study examined the effects of disorientation on the acquisition of different spatial
reference memory tasks. In an appetitively motivated radial arm maze task in which 1 arm …

Damage to the hippocampus has been implicated in the permanent loss of memory in
patients with medial temporal lobe resections. In two previous studies, it was established …

Behavioral tasks must be evaluated in terms of the cognitive functions they require in order
to be performed. All of the tasks described in this chapter can be used with each of four …

The effects of fornix lesions were examined in an object recognition memory test based on
spontaneous exploration. In the standard condition an object (A) was presented in the …

Rats were trained on an automated delayed nonmatching-to-position (DNMP) task. They
then received cytotoxic lesions in either the medial prefrontal cortex (n= 13) or the cingulate …

In a series of 3 experiments it was shown that lesions restricted to the dorsal or ventral
portions of the hippocampus in rats produced different effects on behaviour. Animals with …

Recent ideas about hippocampal function in animals suggest that it may be involved in
memory. A new test for rat memory is described (the despatch task). It has several properties …

Young adult rats with bilateral lesions to the hippocampus or prefrontal cortex, young
operated controls, and normal old rats were tested on two complex mazes in the Hebb …
