“…After removing segments with very large artifacts (exceeding ± 500 lV), eye movements and blinks were corrected using independent component analysis (ICA) and baseline-corrected again. Furthermore, a semiautomatic procedure for artifact detection was applied (amplitude criterion ± 50 lV, gradient 20 lV/sample), again controlled by visual inspection [ 28 ]. Means were then calculated according to experimental and response conditions, referenced to linked mastoids, and the reconstructed FCz reference was added.…”

Coriander is a popular herb with versatile applications. However, the current research about coriander medicinal values have been mainly focusing on its extracts while lacking in the relationship between living coriander plants and emotion. Therefore, this study aims to investigate the effects of coriander plants on human emotions and physiological activities. The results showed that the main Volatile organic compounds (VOCs) of coriander plants were 2-ethyl-1-hexanol, d-limonene, eucalyptol, benzyl alcohol, Isophorone, dimethyl glutarate, α-terpineol, styrene, methyl methacrylate, α-pinene. Coriander plants could significantly reduce the angry sub-scores, alpha amylase and amino acids (arginine, proline, histidine, and taurine) concentrations in saliva. Theta (4–8 Hz) band activity of the cerebral cortex was significantly enhanced. Moreover, taurine significantly positively correlated with anger and negatively correlated with vigor. All the results signified that coriander plant could influence the activity of brain electrophysiological and salivary secretion through its VOCs to improve people’s negative emotions.

“…It has however provided some evidence that this must include mechanisms associated with the control of oxidative stress and neurotrophins, but not inflammation [52]. Thus, it seems clear that somehow systemic inflammation related to mild sepsis modulates the brain response after stress promoted by the CMS protocol, and this may have an impact on the long-term brain dysfunction [53][54][55]. In conclusion, our data suggest that a previous systemic inflammation caused by the induction of mild sepsis could decrease the long-term depressive-like behavior and hippocampal oxidative damage associated with an increase of neurotrophin levels induced by CMS protocol.…”

The systemic inflammation that occurs during severe sepsis can be the cause of long-term consequences. Studies have demonstrated a possible correlation between the neuroinflammatory process and depression. However, the effects of mild sepsis as a tolerant factor for some depressive parameters have not been described. Thus, the objective of this study is to evaluate the effect of mild sepsis on behavioral and biochemical changes on the stress-induced animal model of depression. To this aim, adult male Wistar rats were submitted to cecal ligation and perforation and after 30 days it was submitted to the chronic mild stress protocol (CMS). The animals were submitted to stressors for 40 days. To evaluate the efficacy of CMS induction anhedonia was determined as the amount of sweet food consumption. The levels of neurotrophins and oxidative damage were also evaluated in the hippocampus. It is observed that mild sepsis improved depressive-like parameters after CMS protocol associated with an increase of neurotrophins levels and a decrease of oxidative damage in the hippocampus. In conclusion, our data suggest that a previous mild systemic inflammation caused by the induction of mild sepsis could decrease consequences in the central nervous system (CNS) induced by CMS protocol.

After short delays between encoding and retrieval, healthy young participants have better memory performance for emotional stimuli than for neutral stimuli. Divided-attention paradigms suggest that this emotional enhancement of memory (EEM) is due to different attention mechanisms involved during encoding: automatic processing for negative stimuli, and controlled processing for positive stimuli. As far as we know, no study on the influence of these factors on EEM in Alzheimer's disease (AD) and mild cognitive impairment (MCI) patients, as compared to healthy young and older controls, has been conducted. Thus, the goal of our study was to ascertain whether the EEM in these populations depends on the attention resources available at encoding. Participants completed two encoding phases: full attention (FA) and divided attention (DA), followed by two retrieval phases (recognition tasks). There was no EEM on the discrimination accuracy, independently of group and encoding condition. Nevertheless, all participants used a more liberal response criterion for the negative and positive stimuli than for neutral ones. In AD patients, larger numbers of false recognitions for negative and positive stimuli than for neutral ones were observed after both encoding conditions. In MCI patients and in healthy older and younger controls this effect was observed only for negative stimuli, and it depended on the encoding condition. Thus, this effect was observed in young controls after both encoding conditions, in older controls after the DA encoding, and in MCI patients after the FA encoding. In conclusion, our results suggest that emotional valence does not always enhance discrimination accuracy. Nevertheless, in certain conditions related to the attention resources available at encoding, emotional valence, especially the negative one, enhances the subjective feeling of familiarity and, consequently, engenders changes in response bias. This effect seems to be sensitive to the age and the pathology of participants.
