Empagliflozin alleviates diabetes-induced cognitive impairments by lowering nicotinamide adenine dinucleotide phosphate oxidase-4 expression and potentiating the antioxidant defense system in brain tissue of diabetic rats
CONCLUSION: Uncontrolled diabetes negatively impacts mental function and impairs learning and cognitive performance via oxidative stress induction, the Nox-4 enzyme playing a central role. Empagliflozin reverses these effects, improving cognitive ability via promoting the anti-oxidative system and damping Nox-4 free radical generator enzyme expression. Therefore, empagliflozin is a promising treatment, providing both antidiabetic and extra-glycemic benefits for improving brain function in the diabetic milieu.PMID:38141785 | DOI:10.1016/j.bbr.2023.114830 (Source: Behavioural Brain Research)

The role of serotonin in modulating social competence in a cooperatively breeding fish
Behav Brain Res. 2023 Dec 21:114819. doi: 10.1016/j.bbr.2023.114819. Online ahead of print.ABSTRACTBehavioural interactions between conspecifics rely on the appreciation of social cues, which is achieved through biochemical switching of pre-existing neurophysiological pathways. Serotonin is one of the major neurotransmitters in the central nervous system responsible for the modulation of physiological and behavioural traits, in particular social behaviour. The relative importance of serotonin in modulating optimal social responses to the available social information (i.e., social competence) is yet unknown. Here we investi...

Differential effect of chronic mild stress on anxiety and depressive-like behaviors in three strains of male and female laboratory mice
Behav Brain Res. 2023 Dec 21:114829. doi: 10.1016/j.bbr.2023.114829. Online ahead of print.ABSTRACTMajor depressive disorder is the most common psychiatric disorder worldwide. To understand mechanisms and search for new approaches to treating depression, animal models are crucial. Chronic mild stress (CMS) is the most used animal model of depression. Although CMS is considered a robust model of depression, conflicting results have been reported for emotion-related behaviors, which the intrinsic characteristics of each rodent strain could explain. To further shed light on the impact of genetic background on the relevant par...

Extraction of brain function pattern with visual-capture-task fMRI using dynamic time-window method in ADHD children
Behav Brain Res. 2023 Dec 20:114828. doi: 10.1016/j.bbr.2023.114828. Online ahead of print.ABSTRACTAttention deficit/Hyperactivity disorder (ADHD) has a great impact on children's development. This paper uses a novel adaptive brain state extraction algorithm to construct a dynamic time-window brain network, which captures the brain function pattern characteristics of ADHD children with higher temporal resolution. The test data were acquired by functional magnetic resonance imaging (fMRI) obtained from 23 children with ADHD during the visual-capture-task [age: (8.27 ± 2.77)]. A spatial standard deviation method is used aft...

Are blind individuals immune to bodily illusions? Somatic rubber hand illusion in the blind revisited
Behav Brain Res. 2023 Dec 20:114818. doi: 10.1016/j.bbr.2023.114818. Online ahead of print.ABSTRACTMultisensory awareness of one's own body relies on the integration of signals from various sensory modalities such as vision, touch, and proprioception. But how do blind individuals perceive their bodies without visual cues, and does the brain of a blind person integrate bodily senses differently from a sighted person? To address this question, we aimed to replicate the only two previous studies on this topic, which claimed that blind individuals do not experience the somatic rubber hand illusion, a bodily illusion triggered ...

Evaluation of a headphones-fitted EEG system for the recording of auditory evoked potentials and mental workload assessment
In this study, we evaluated the relevance of a headphone- mounted electroencephalogram (EEG) system for monitoring mental workload. The participants (N=12) were instructed to pay attention to auditory alarms presented sporadically while performing the Multi-Attribute Task Battery (MATB) whose difficulty was staged across three conditions to manipulate mental workload. The P300 Event-Related Potentials (ERP) elicited by the presentation of auditory alarms were used as probes of attentional resources available. The amplitude and latency of P300 ERPs were compared across experimental conditions. Our findings indicate that the...

Bifidobacterium breve M-16V regulates the autonomic nervous system via the intestinal environment: A double-blind, placebo-controlled study
Behav Brain Res. 2023 Dec 19:114820. doi: 10.1016/j.bbr.2023.114820. Online ahead of print.ABSTRACTWe conducted a randomized controlled trial to investigate the potential of Bifidobacterium breve M-16V to improve mood in humans. In this evaluation, we incorporated the use of near-infrared spectroscopy (NIRS), which has been used to evaluate mood states in studies with small sample sizes. Participants were given B. breve M-16V (20 billion cells/day) for 6 weeks, and their mood state was assessed before and after ingestion. NIRS data were collected at rest and during a mental arithmetic task (under stress). Intake of B. brev...

Impact of Voluntary Exercise Training on the Metabolic and Behavioral Characteristics of the rTg4510 Transgenic Mouse Model of Frontotemporal Dementia
Behav Brain Res. 2023 Dec 18:114810. doi: 10.1016/j.bbr.2023.114810. Online ahead of print.ABSTRACTFrontotemporal dementia (FTD) is a neurodegenerative disorder that affects the frontal and temporal lobes of the brain, primarily in individuals under 65 years of age, and is the second most common form of dementia worldwide. There is no cure for FTD and current treatments offer limited symptomatic relief. Regular physical activity exhibits cognitive and neuroprotective benefits in healthy individuals and in various neurodegenerative diseases, such as Alzheimer's disease, but few studies have examined its efficacy in FTD.

Environmental enrichment changes the effects of prenatal and postnatal undernutrition on memory, anxiety traits, Bdnf and TrkB expression in the hippocampus of male adult rats
Behav Brain Res. 2023 Dec 18:114817. doi: 10.1016/j.bbr.2023.114817. Online ahead of print.ABSTRACTEnvironmental factors such as undernutrition and environmental enrichment can promote changes in the molecular and behavioural mechanisms related to cognition. Herein, we investigated the effect of enriched environment stimulation in rats that were malnourished in the pre- and postnatal periods on changes in the gene expression of brain-derived neurotrophic factor and its receptor in the hippocampus, as well as on anxiety traits and memory. Early undernutrition promoted weight reduction, increased the risk analysis, reduced p...
