1. Effect of repeated restraint stress on memory in different tasks
The present study investigated the effect of repeated stress applied to female rats on memory evaluated by three behavioral tasks: two-way shuttle avoidance, inhibitory avoidance and habituation to an open field. Repeated stress had different effects on rat behavior when different tasks were considered. In the two-way active avoidance test the stressed anima

2. Reproduction of Leptodactylus ocellatus (Anura, Leptodactylidae), a species with maternal care to the offspring / Reprodução de Leptodactylus ocellatus (Anura, Leptodactylidae), uma espécie com cuidado maternal à prole
In Leptodactylus ocellatus, the tadpoles form schools that are protected by the females until the end of the larval phase. Here we described aspects of the reproduction of this species in areas of Cerrado in the state of Minas Gerais (Brazil). We determined in the field the reproductive period, spawning places, duration of the parental care and differences i

3. Complex Effects of NMDA Receptor Antagonist APV in the Basolateral Amygdala on Acquisition of Two-Way Avoidance Reaction and Long-Term Fear Memory
Although much has been learned about the role of the amygdala in Pavlovian fear conditioning, relatively little is known about an involvement of this structure in more complex aversive learning, such as acquisition of an active avoidance reaction. In the present study, rats with a pretraining injection of the N-methyl-D-aspartate (NMDA) receptor antagoni

4. A Quantitative Trait Locus Influencing Anxiety in the Laboratory Rat
A critical test for a gene that influences susceptibility to fear in animals is that it should have a consistent pattern of effects across a broad range of conditioned and unconditioned models of anxiety. Despite many years of research, definitive evidence that genetic effects operate in this way is lacking. The limited behavioral test regimes so far used in

5. Mice lacking the gene encoding tissue-type plasminogen activator show a selective interference with late-phase long-term potentiation in both Schaffer collateral and mossy fiber pathways.
The gene encoding tissue-type plasminogen activator (t-PA) is an immediate response gene, downstream from CREB-1 and other constitutively expressed transcription factors, which is induced in the hippocampus during the late phase of long-term potentiation (L-LTP). Mice in which the t-PA gene has been ablated (t-PA-/-) showed no gross anatomical, electrophysio
