Summary: This study examined the effects of an 8-week mindful eating intervention on reward anticipation using fMRI. The results showed that mindful eating reduced caloric reward responses in the midbrain, but not in the striatum. The study also found temporary beneficial effects of the control intervention on BMI, waist circumference, and diet quality.

Summary: How to retrieve latent neurobehavioural processes from complex neurobiological signals is a challenge that has not been fully addressed. This study presents a novel approach, DeCoP, that outperforms traditional decoding methods in terms of false inference and robustness. The research reveals distinct evaluation and readiness processes during reward/punishment anticipation, modulated by different dopamine systems. Only a few brain regions encode exact input information, while others encode abstract information.

Summary: Aberrations in how people form expectations about rewards and how they respond to receiving rewards are thought to underlie major depressive disorder. To examine the neural correlates of monetary anticipation and outcome in depressed subjects, functional neuroimaging studies were conducted using the monetary incentive delay task. The results showed heightened cortical response during reward anticipation and reduced response in the mesocortico-limbic circuit during both anticipation and outcome stages in depressed patients.

Summary: Understanding the neurobiology of social reward processing is crucial for reducing maladaptive social behaviors and enhancing healthy social life. Current research suggests that oxytocin plays a role in the processing of social rewards. However, studies in humans have shown mixed results. This review summarizes 19 studies that investigated the effects of intranasal oxytocin administration on social reward processing. The findings indicate that oxytocin is most effective during the consumption phase of social rewards and may modulate the activity of several brain regions.

Summary: Neuroimaging studies have shown that using the brain activity of a group of individuals can predict the behavior of an independent group. In this study, the researchers aimed to forecast the aggregate choices in a popular restaurant chain using functional magnetic resonance imaging (fMRI). The study found that activity in the ventral striatum, as defined by a task-specific region of interest, significantly correlated with the one-year sales of the restaurant chain (r = 0.28, p = 0.01). Regression analysis combining ventral striatum activity with objective product characteristics, behavioral, and survey data yielded an R-2 value of 0.33. These results confirm previous studies suggesting that the brain activity of a relatively small number of individuals can predict the choices of a larger independent group.

Summary: An imaging platform using self-supervised deep learning was used to study the effects of cocaine on cerebral blood flows in awake mice. The study employed ultrahigh-resolution optical coherence Doppler tomography to visualize the dynamics of cerebral blood flow velocity (CBFv) in awake mice, and utilized deep learning techniques to denoise and remove motion artifacts from the images. The results showed that acute cocaine induced vasoconstriction and decreased CBFv, with larger decreases observed under isoflurane anesthesia compared to awake or dexmedetomidine anesthesia. Chronic cocaine use in awake mice caused severe vasoconstriction, decreased CBFv, and vascular adaptations in the form of extended branching arteriolar/venular vessels. The 3D imaging platform presented in this study provides a powerful tool for studying dynamic changes in vessel diameters and morphology, as well as CBFv networks, in awake animals.

Summary: This study is the first to explore the functional characteristics of the mouse visual system using fMRI, and found that under anesthesia, mice showed stronger and more widespread BOLD responses compared to the awake state. Additionally, the BOLD response to visual stimuli was faster and stronger in awake mice compared to anesthetized mice.

Summary: Research suggests that increased neural activation to loss in adolescents who initiate alcohol use may indicate initial vulnerability to alcohol use in adolescence. These results highlight the importance of neural activation in brain regions associated with salience, error detection/self-referential processing, and sensorimotor function in understanding adolescent alcohol initiation.

Summary: The brain corticostriatal circuits play a crucial role in understanding chronic pain. In this study, the authors investigated the connectivity of the nucleus accumbens (NAcc) - medial prefrontal cortex (MPFC) circuit in patients with fibromyalgia. They found that the connectivity of this circuit was significantly reduced in fibromyalgia patients compared to healthy controls. The connectivity between the NAcc and subcortical brain regions was also reduced in fibromyalgia. These findings provide novel evidence of altered corticostriatal and mesolimbic circuits in chronic pain.

Summary: The locus coeruleus (LC) in the pons is the main source of noradrenaline (NA) to the forebrain. Recent studies have shown that LC-NA neurons can be heterogeneous and exhibit distinct coding modes. However, the mechanisms behind the unique functional properties of LC-NA neuronal subpopulations remain unclear.

Summary: Functional ultrasound (fUS) imaging provides a method for visualizing deep brain activity by measuring cerebral blood volume changes coupled with neural activity, while functional MRI (fMRI) relies on the blood-oxygenation-level-dependent signal. Resting-state functional MRI (rsfMRI) allows for whole brain functional imaging and estimation of resting-state networks (RSNs). Recent research suggests that fUS can provide similar RSNs to fMRI but with higher temporal resolution and stronger correlation with neural activity. These findings have the potential to advance our understanding of functional brain networks and their relationships with disease models.

Summary: Hand preference is a behavioral expression of brain lateralization. This study used the gPPI approach to investigate functional connectivity changes during single-hand movement in right-hand subjects. The results showed increased functional connectivity in interhemispheric motor-related regions during non-dominant hand movement, while there was no increase during dominant hand movement. Additionally, the combination of GLM and gPPI analysis can more clearly detect hand preference lateralization.

Summary: Potato starch suspension (PSS) shows potential in addressing issues related to micro-magnetic resonance imaging (micro-MRI) of ex vivo embryos, such as air bubbles and specimen motion. This paper presents a protocol for using PSS in micro-MRI scanning, including steps for sample and potato starch preparation with phosphate-buffered saline, as well as specimen immersion and micro-MRI scanning. The protocol is applicable not only to embryos but also to other specimens like insects. For complete details, please refer to Tsurugizawa et al.1.

Summary: Many funding agencies have emphasized the importance of considering sex as a biological variable in experimental design to improve the reproducibility and translational relevance of preclinical research. Omitting the female sex from experimental designs in neuroscience and pharmacology can result in biased or limited understanding of disease mechanisms. This article provides methodological considerations for incorporating sex as a biological variable in in vitro and in vivo experiments, including the influence of age and hormone levels, and proposes strategies to enhance methodological rigor and translational relevance in preclinical research.
