The insular cortex modulates cardiovascular responses to acute restraint stress in rats
(ELSEVIER SCIENCE BV, 2010)
Acute restraint is an unavoidable stress situation that evokes marked and sustained cardiovascular changes, which are characterized by blood pressure and heart rate increases. In the present study, we tested the hypothesis ...
DIFFERENT ROLE OF THE VENTRAL MEDIAL PREFRONTAL CORTEX ON MODULATION OF INNATE AND ASSOCIATIVE LEARNED FEAR
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
Reversible inactivation of the ventral portion of medial prefrontal cortex (vMPFC) of the rat brain has been shown to induce anxiolytic-like effects in animal models based on associative learning. The role of this brain ...
Papel do córtex pré-frontal medial na ansiogênese induzida pelo estresse de derrota social em camundongos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em Ciências FisiológicasCâmpus São Carlos, 2018-10-18)
Recent findings have demonstrated that the medial prefrontal cortex (mPFC) has a lateralized role in the control of response to stressors, and the left hemisphere (LmPFC) would attenuate the anxiogenic responses elicited ...
Interaction of dopamine D1 with NMDA NR1 receptors in rat prefrontal cortex
Despite the tremendous importance of D1 and NMDA receptors to cognition (working memory, executive functions) and synaptic plasticity in the prefrontal cortex (PFC), little is known about the molecular mechanisms underlying ...
Psicolatina : caracterização conformacional e avaliação do efeito sobre os níveis de aminoácidos excitatórios e inibitórios em regiões cerebrais de roedoresPsychollatine : conformational characterization and evaluation of the effects on the excitatory and inhibitory amino acids levels in brain regions of rodents
Sensibilização cruzada entre anfetamina e nicotina: avaliação neuroquímica do núcleo acumbens e córtex préfrontal em ratos adolescentes e adultos
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Ciências Fisiológicas, 2009-09-24)
Nicotine and psychostimulants are often abused in combination. Drug abuse often begins during adolescence. Exposure to drugs of abuse during adolescence can have long-term consequences. We have previously demonstrated that ...
Asymmetry of interhemispheric responses evoked in the prefrontal cortex of the rat
Interhemispheric responses of anesthetized rats were evoked in the prefrontal cortex of both cerebral hemispheres by electric stimulation of the homologous contralateral cortical region. Fatigability of interhemispheric ...
Differential effect of environment enrichment and social isolation on depressive-like behavior, spontaneous activity and serotonin and norepinephrine concentration in prefrontal cortex and ventral striatum
Dawley rats were reared from weaning in either social isolation, standard laboratory conditions, or environmental enrichment. Open-field activity was assessed at postnatal days 37, 65, 93 and 107 and 1 h before the last ...
Proteomic analysis of dorsolateral prefrontal cortex indicates the involvement of cytoskeleton, oligodendrocyte, energy metabolism and new potential markers in schizophrenia
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
Schizophrenia is likely to be a consequence of serial alterations in a number of genes that, together with environmental factors, will lead to the establishment of the illness. The dorsolateral prefrontal cortex (Brodmann`s ...
Medial prefrontal cortex is a crucial node of a rapid learning system that retrieves recent and remote memories
The neocortex is thought to be a distributed learning system that gradually integrates semantic information into the initial mnemonic representation rapidly formed by the hippocampus after acquisition. Nevertheless, an ...
