Inbred mice show strain-specific differences in the hippocampal mossy fiber projection. These differences are most pronounced in the portion of the projection that forms synaptic connections with the basal dendrites of the CA3 pyramidal neurons [intra- and infrapyramidal mossy fiber (IIP-MF) projection]. We have previously demonstrated that the extent of the IIP-MF subfield is positively corre...
This research reports the effects of two metabolic groups of bacteria on physiological activity and cognitive function in C57BL/6 mice. In one experiment, the mice on a diet supplemented with red kidney bean for 24 hr were able to complete an eight-arm radial learning maze in a shorter time than mice on a diet without red kidney beans. The median time required for mice to complete the maze when...
The effects of bilateral electrolytic lesions of the "shell" subterritory of the nucleus accumbens in the rat were examined on 2 tasks known to be sensitive to hippocampal damage. Experiment 1 tested the effects of shell lesion on delayed non-matching-to-sample (DNMS) task in a T-maze. The maze was rotated 180 degrees after the end of acquisition. Experiment 2 used a 4-arm baited, 4-arm unbaite...
NMDA receptors (NMDARs) containing NR2A (epsilon1) subunits are key contributors to hippocampal long-term potentiation (LTP) induction in adult animals and have therefore been widely implicated in hippocampus-dependent spatial learning. Here we show that mice lacking the NR2A subunit or its C-terminal intracellular domain exhibit impaired spatial working memory (SWM) but normal spatial referenc...
We examined the effects of long-term adrenalectomy (ADX) on hippocampal anatomy and behavioral learning in two spatial memory tasks. We assessed damage throughout the hippocampus by stereological analysis of the dentate gyrus and Ammon's horn. Rats were ADX or sham operated, and then tested in the Morris water maze 12 weeks after surgery, followed by testing on an eight-arm, alternating-baited ...
Behavioral characteristics of the animal models and humans are impaired in chronic stress. The present study aimed to evaluate and compare the protective effects of sertraline and curcumin on stress-induced learning and memory impairment, anxiety and anhedonia in rats. Male rats were divided into seven groups: stress+water, stress+olive oil, stress+curcumin (100 mg/kg/day), stress+sertraline (1...
BACKGROUND Effects of orally administered daytime melatonin on novelty induced behaviors and spatial working memory in mice were evaluated using the open field, the Y maze and the radial arm maze. PURPOSE To ascertain the possible nootropic and/or central excitatory or inhibitory effects of daytime oral melatonin in mice. METHODS Adult male mice from our colony, assigned to three and four g...
