Raphe nuclei echogenicity changes in major depression
Background: Major depression is a common disorder with great social and individual burdens. Transcranial sonography (TCS) is a useful and noninvasive measure for assessment of normal and impaired brain parenchyma. The brainstem raphe nuclei are in close association with dorsocaudal limbic system and plays an important role in depression. In this study we compared the echogenicity of the r...
متن کاملChallenges in the differentiation of midbrain raphe nuclei in neuroimaging research.
The work by Takahashi et al. (1) recently reported a negative association between brainstem serotonin transporters and personality traits such as honesty and rejection to unfairness. They interpret their locus within brainstem to include the dorsal raphe nucleus (DRN) (1). Other than DRN, the median raphe nucleus (MRN) also projects to the forebrain and may be equally important in the serotoner...
متن کاملEstradiol increases Pet-1 and serotonin transporter mRNA in the midbrain raphe nuclei of ovariectomized rats.
Previous research has shown that estradiol increases the anorexia associated with serotonin (5-HT) neurotransmission. To examine further the putative relationship between estradiol and 5-HT, we investigated whether estradiol increases the expression of Pet-1 and the 5-HT transporter (5-HTT), two genes implicated in the development and regulation of the 5-HT system. Ovariectomized (OVX) rats (n=...

متن کاملCannabinoid CB1 Receptors Mediate the Gastroprotective Effect of Neurotensin
Objective(s) Several lines of evidence indicate that neuropeptides exhibit protective properties against gastroduodenal ulcers. Neurotensin, a gut-brain neuropeptide, is implicated in a number of physiological processes in the central nervous system and peripheral tissues including gastrointestinal tract. In the present study, we aimed to investigate the gastroprotective potential of either p...
