Summary: The study revealed the relationship between inhibitory control and obesity, as well as the interactions between gut microbiota, metabolomics, and brain structure. Metabolic pathway alterations associated with obesity were found to be linked to inhibitory control, and results were validated in mice through fecal microbiota transplantation.

Summary: The glutamatergic projections from the lateral habenula (LHb) to the dorsal raphe nucleus (DRN) modulate male mice's aggressive behavior. Inhibition of LHb-DRN projection blocks the increase in aggression after social instigation. The activity of this pathway is not necessary for the expression of species-typical aggressive behavior but essential for the increase in aggression resulting from social instigation.

Summary: The study reveals that dopamine and serotonin modulate excitatory synaptic transmission in the nucleus accumbens in input-specific ways, influencing motivated behaviors differently. Endogenous release of DA and 5-HT, as well as optogenetic inhibition, alter the behavioral effects of drugs in distinct manners.

Summary: Alzheimer's disease (AD) is a devastating neurodegenerative disorder for which an effective therapy has yet to be found. Research suggests that early damage to the ascending monoaminergic system in the brainstem may be an early sign and potential trigger of AD. In addition, cortical malfunction and local neurohistopathology are also related to the progression of AD.

Summary: Metazoans utilize protein homeostasis pathways to respond to adverse conditions, with the nervous system playing a role in regulating proteostasis in different tissues. This study reveals that Caenorhabditis elegans uses biogenic amine neurotransmitters to modulate UPS proteostasis in epithelia by promoting eicosanoid production through P450 monooxygenases, ultimately maintaining protein turnover.

Summary: Researchers report a study that combines high-resolution MRI and detailed histology to study the impact of neurologic disease on specific cell groups in the human brainstem and cerebellum. These findings are crucial for understanding and diagnosing brainstem lesions.

Summary: Early life is a critical period where enhanced neural plasticity allows the developing brain to adapt to its environment. Exposure to fluoxetine in early postnatal period can lead to reduced effort-related motivation and blunted dopaminergic activation in reward tasks in adulthood. Administering bupropion in adulthood can rescue the reduction in motivation, highlighting the involvement of the dopaminergic system in this process.

Summary: Nanodiamond is a type of carbon nanomaterial that can be used to detect neurotransmitters that provoke physiological responses, but there are limited electrochemical ND-based NT sensors available. The study focused on the performance of existing sensors, interactions between NTs and NDs, and the lack of data on the subject.

Summary: This study presents a protocol for the simultaneous electroanalysis of tryptamine, serotonin, and dopamine using a conducting poly-murexide-based electrode, the first report of its kind. The analytes underwent irreversible electro-oxidation at the modified electrode surface under optimized conditions, with linear ranges for dopamine, serotonin, and tryptamine. The specificity of the developed electrode was satisfactory in the presence of other biomolecules, and electroanalysis was demonstrated in human serum for these targets.

Summary: This review provides a comprehensive overview of the drug design, development, and therapy of lurasidone for schizophrenia treatment. Lurasidone has specific effects on different receptors and has been found to be effective in improving symptoms and preventing relapse in patients with schizophrenia. It also has minimal metabolic side effects and improves cognitive and functional performance.

Summary: This study examined the effects of manipulating serotonin receptors on alcohol self-administration and alcohol-seeking behavior in rats. The results showed that blocking 5-HT2A receptors had limited effects on reducing alcohol-seeking, while activating 5-HT2C receptors had a broader range of effects on reducing alcohol self-administration, alcohol drinking, and alcohol-seeking behavior.

Summary: This article discusses the evolution of nervous systems to adapt to the dynamics of the environment and explains this process through the study of learning and decision-making. The article focuses on the slow dynamics of neuronal networks and the role of neuromodulators in temporal scaling.

Summary: The treatment strategies for phenylketonuria (PKU) include PEG-PAL and rAAV-based PAH gene delivery, both of which lower Phe levels and have therapeutic effects on brain pathology; however, PAL delivery requires dose optimization, does not increase Tyr levels in the brain, and may elicit an immune response; the impact of high Phe levels on liver functions involves changes in lipid metabolism and upregulation of genes related to cholesterol biosynthesis.

Summary: Neurotransmitters play crucial roles in regulating neural circuit dynamics in the central and peripheral nervous systems, including the gastrointestinal tract. However, there is a lack of bioelectronic tools for real-time monitoring of neurotransmitter dynamics in vivo, especially in the enteric nervous system. In this study, the researchers developed a tissue-mimicking, stretchable neurochemical biological interface called NeuroString, which allows chronic in vivo real-time monitoring of monoamine levels in the brain and serotonin dynamics in the gut. This interface has the potential for studying the impact of neurotransmitters on gut microbes and brain-gut communication.
