La enfermedad de Alzheimer y la demencia frontotemporal, son las principales causas del envejecimiento cogniti...

Systemic injection of an H4 receptor agonist induces a decrease in CREB and pCREB levels in the cerebellar vermis and prefrontal cortex in mice

Braz. j. med. biol. res; 52 (5), 2019
Studies have shown that an injection with the histamine H4 receptor agonist VUF-8430 modulates emotional memory processes. In the present study, the aim was to verify if intraperitoneal (ip) injection of VUF-8430 (500 ng/kg) in mice affects the synthesis of proteins required for memory consolidation proc...

The limbic-reticular coupling theory of memory processing in the brain and its greater compatibility over other theories

Dement. neuropsychol; 12 (2), 2018
Abstract The limbic-reticular coupling theory suggests that the hippocampus and amygdala regulate such descending limbic structures as the mammillary bodies, septum, hypothalamus and epithalamus to regulate the ascending noradrenergic, serotonergic, dopaminergic and cholinergic systems, performing declar...

Electroacupuncture ameliorate learning and memory by improving N -acetylaspartate and glutamate metabolism in APP/PS1 mice

Salivary cortisol during memory encoding in pregnancy predicts postpartum depressive symptoms: a longitudinal study

Abstract Introduction Postpartum depression (PPD) is a common disorder that substantially decreases quality of life for both mother and child. In this longitudinal study, we investigated whether emotional memory, salivary cortisol (sCORT) or alpha-amylase during pregnancy predict postpartum depressive s...

Stress and Cognitive Reserve as independent factors of neuropsychological performance in healthy elderly

Abstract Exposure to high levels of cortisol and self-reported stress, as well as cognitive reserve, have been linked to Alzheimer’s disease pathology. However, there are no studies on the interaction of these variables. The present study aims to assess the associations of measures of cortisol, sel...

The maintenance of modified electroconvulsive therapy combined with risperidone is better than risperidone alone in preventing relapse of schizophrenia and improving cognitive function

Arq. neuropsiquiatr; 74 (10), 2016
ABSTRACT Objective To evaluate the effect of maintenance modified electroconvulsive therapy (MECT) on schizophrenic patients. Methods From June 2012 to June 2014, 62 patients with schizophrenia, who had recovered from a successful course of acute MECT, were recruited. Thirty-one patients received mai...

Effects of crocin on brain oxidative damage and aversive memory in a 6-OHDA model of Parkinson's disease

Arq. neuropsiquiatr; 74 (9), 2016
ABSTRACT The purpose of the present study was to investigate the effect of crocin on brain oxidative damage and memory deficits in a 6-hydroxydopamine (6-OHDA) model of Parkinson’s disease. Male Wistar rats were subjected to unilateral injection of 6-OHDA (16 µg) into the medial forebrain bundle a...
