Thirty-three monkeys took part in seven experiments designed to elucidate further the effect
of fornix transection on learning and memory. In the first experiment the monkeys had to …

Three experiments assessed the ability of male Sprague-Dawley rats to organize the spatial
locations of different food types in a hierarchical manner to maximize the efficiency of …

Win-shift spatial memory tasks in a radial maze reinforce animals for avoiding previously
visited rewarded arms; win-stay tasks reinforce them for returning to those arms. Win-shift …

In order to test whether there is a correspondence in function of prefrontal cortex in rats and
humans, rats with medial prefrontal cortex lesions were tested for item and order memory for …

A differentiation was made between dispositional memory and representational memory. A
delayed nonmatching-to-sample task in a T-maze operationalized this distinction …

The effects of cytotoxic lesions in either the anterior cingulate cortex or the retrosplenial
cortex were compared with those of fornix lesions on three tests of spatial memory. Two of …

Four experiments were performed with macaque monkeys (rhesus, Macaca mulatta, and
cynomolgus, M. fascicularis). In experiment 1 six rhesus monkeys learned pre-operatively to …

Rats were trained and tested on a hierarchical radial maze, which consisted of eight primary
alleys radiating from a central platform and three secondary alleys which branched off the …

The effects of isolating the hippocampus from its neocortical inputs and outputs by damaging
the deep layers of entorhinal cortex and subiculum were compared with direct removal of the …

Rats with medial prefrontal cortex, hippocampus, or cortical control lesions were tested on
an eight-arm radial maze task, in order to examine memory for the temporal order of spatial …
