BACKGROUND Deep brain stimulation (DBS) is being investigated as a treatment for major depression, but its mechanisms of action are still unknown. We have studied the effects of ventromedial prefrontal cortex (vmPFC) stimulation in a chronic model of depression and assessed the involvement of the serotonergic system and brain derived neurotrophic factor(More)
While considerable clinical evidence implicates thyroid hormones (THs) in depressive illness, the specific nature of this involvement remains unclear. The alpha1 subtype (TR-alpha1) is the most abundant TH receptor in brain. Here we investigated changes in TR-alpha1 mRNA in the chronic mild stress (CMS) model of depression. Rats were exposed to a CMS(More)
AIMS To investigate the effects of using bromazepam on the relative power in alpha while performing a typing task. Bearing in mind the particularities of each brain hemisphere, our hypothesis was that measuring the relative power would allow us to investigate the effects of bromazepam on specific areas of the cortex. More specifically, we expected to(More)
The relevance of automatically identifying rhetorical moves in scientific texts has been widely acknowledged in the literature. This study focuses on abstracts of standard research papers written in English and aims to tackle a fundamental limitation of current machine-learning classifiers: they are mono-labeled, that is, a sentence can only be assigned one(More)
Based on observations in five patients, we review the main theories concerning dreams and propose a comprehensive theory on their cognitive function. We classify dreams based on the role performed by them in inhibition, stimulation or creation of cognitive strategies around an emotional nucleus. These are stored in the memory bank and retrieved by an(More)
BACKGROUND Evidence on the diagnostic performance of palpatory methods and possible confounding factors is scarce. OBJECTIVES To examine the sensitivity of palpatory methods for location of lumbopelvic landmarks and to assess its association with personal characteristics. METHODS Eighty-three participants (41 men, 55.6 (16.5) years, 25.9 (4.8) kg/m2(More)
