1. Behavior of a Model for Feedback-Controlled Reverberating Circuit and Immediate Memory Function
RESUMO Neste trabalho, implementamos um modelo matemático de transmissão sináptica conectando neurônios em um circuito de descargas reverberantes, a fim de investigar seu comportamento diante de variações paramétricas. Usando um programa desenvolvido em linguagem C, verificamos se o modelo se comportaria como um circuito de memória de curto prazo. Na

2. Effects of carvacrol and physical exercise on motor and memory impairments associated with Parkinson’s disease
RESUMO O presente estudo foi realizado para investigar os efeitos do carvacrol e do exercício em esteira sobre o déficit de memória, comportamento rotacional e biomarcadores de estresse oxidativo em um modelo animal (ratos lesionados por 6-OHDA) da doença de Parkinson (DP). Ratos Wistar foram tratados com carvacrol na dose de 25 mg/kg e/ou correram em um

4. Small-scale environmental enrichment and exercise enhance learning and spatial memory of Carassius auratus, and increase cell proliferation in the telencephalon: an exploratory study
Carassius auratus is a teleost fish that has been largely used in behavioral studies. However, little is known about potential environmental influences on its performance of learning and memory tasks. Here, we investigated this question in C. auratus, and searched for potential correlation between exercise and visuospatial enrichment with the total number of

5. Adrenergic receptor β3 is involved in the memory consolidation process in mice
Attention and emotion have a positive impact on memory formation, which is related to the activation of the noradrenergic system in the brain. The hippocampus and amygdala are fundamental structures in memory acquisition, which is modulated by noradrenaline through the noradrenergic receptors. Pharmacological studies suggest that memory acquisition depends o

6. Chronic intermittent exposure to ayahuasca during aging does not affect memory in mice
The Quechua term ayahuasca refers to a beverage obtained from decoctions of the liana Banisteriopsis caapi with leaves of Psychotria viridis. The ritualistic use of ayahuasca is becoming a global phenomenon, with some individuals using this beverage throughout life, including in old age. Cognitive impairment is a common manifestation during aging. There are

7. An ontogenic study of the behavioral effects of chronic intermittent exposure to ayahuasca in mice
Ayahuasca is a beverage obtained from decoctions of the Banisteriopsis caapi plus Psychotria viridis. In religious contexts, ayahuasca is used by different age groups. However, little is known of the effects of ayahuasca during ontogenic development, particularly with regard to the functional characteristics of the central nervous system. Animal models are u

8. Thalassophryne nattereri fish venom: from the envenoming to the understanding of the immune system
Thalassophryne nattereri (niquim) is a venomous fish found off North and Northeast coast of Brazil, where it is known by the severity of the accidents involving humans. This review article is divided into four topics. The first one provides a brief description of the animal biology and its distribution off Brazilian coastal waters, the venom apparatus, signs

9. Translational realistic expectations of chronic cerebral hypoxemia in rat model after bilateral commom carotid artery ligation. Neurocognitive aspects
PURPOSE: To evaluate the effects of chronic cerebral hypoxia on memory of rats submitted to bilateral common carotid artery ligation (BCCL). METHODS: Every each week, for 16 weeks, 31 rats were tested for memory using a water and land mazes and compared with 30 normal rats (control group A). The variables were expressed by their mean and standard error

10. Learning and survival memory undergoing a permanent bilateral carotid ligation in rats
PURPOSE: To evaluate the effect of cerebral hypoxia-ischemia on memory and learning survival of rats submitted to permanent bilateral carotid ligation (PBCL). METHODS: Twenty-four survivors of PBCL were evaluated after 30 days with regard to memory and learning using a water survival maze. Twenty-three healthy rats were used as control group. The results wer

11. Animal models for predicting the efficacy and side effects of antipsychotic drugs
The use of antipsychotic drugs represents an important approach for the treatment of schizophrenia. However, their efficacy is limited to certain symptoms of this disorder, and they induce serious side effects. As a result, there is a strong demand for the development of new drugs, which depends on reliable animal models for pharmacological characterization.

12. Avaliação da memória emocional em camundongos : efeito da injeção de midazolam na substância cinzenta periaquedutal
Varios estudos tem demonstrado que os benzodiazepinicos (BDZ), administrados na substancia cinzenta periaquedutal (SCP), podem produzir efeito ansiolitico em diferentes modelos animais de ansiedade e tambem prejudicar a aprendizagem e a memoria em roedores. Apesar do ja conhecido papel da SCP em modular comportamentos defensivos em modelos animais, pouco se
