Summary: The research shows that olfaction can modulate low-level perception of other sensory modalities without specific training, as demonstrated through psychophysical and neuroimaging experiments. Results suggest that the olfactory-visual effect is an innate behavior rather than an acquired one, providing new insights into the fundamental roles of olfactory function.

Summary: Measures of behavioral sensitivity are important for selecting stimulus concentrations in experiments. This study focused on acetate esters and found that mice are most sensitive to isobutyl acetate and least sensitive to propyl acetate. These updated measures of sensitivity will help guide experimenters in choosing appropriate stimulus concentrations for experiments.

Summary: Odor identification abilities decline with age, with high-intensity odors being easier to identify overall but more affected by old age. Identification likelihood is proportional to the perceived intensity of the odor, and it is also associated with perceived pleasantness and edibility.

Summary: The study revealed altered brain organization in patients with OCD compared to healthy controls using individual-based approaches to maximize the identification of underlying network-based features specific to the OCD group. This suggests differences in functional architecture in patients with OCD and control groups, indicating potential unique patterns in OCD pathophysiology.

Summary: By analyzing an accurate machine learning model for human odor perception, a computable representation for odor at the molecular level was discovered, which can predict the odor-evoked receptor, neural, and behavioral responses of almost all terrestrial organisms studied in olfactory neuroscience. This olfactory representation, known as the principal odor map (POM), shows that odorous compounds with similar POM representations are more likely to co-occur within a substance and be metabolically closely related. Despite large jumps in molecular structure, metabolic reaction sequences also follow smooth paths in POM. It suggests that the brain's representation of the olfactory world is shaped by the natural statistics of metabolism, similar to how the brain's visual representations have evolved around the natural statistics of light and shapes.

Summary: This study investigated the neural processing of odors with different degrees of association with well-being. The findings showed increased activation in higher-order cognitive and emotional regions, such as the angular gyrus and anterior cingulate cortex, suggesting a role of odors in influencing individual well-being and the key role of the angular gyrus in shifting attention.

Summary: Research shows that the cerebellum plays a significant role in language understanding, particularly in processing high-level conceptual language features, with recent findings contradicting theories related to low-level acoustic or phonemic features. Additionally, the cerebellum has been found to exhibit a higher response to social semantic categories, indicating a preference for social information in language representation.

Summary: Patients experience olfactory dysfunction after laryngectomy, and the odour-blowing test is superior to the odour-sniffing test in detecting residual olfaction. Simply blowing a scent is insufficient to obtain good olfaction; active airflow is crucial for recognizing odours.

Summary: In recent years, researchers have extensively explored the multisensory integration of visual and olfactory stimuli and identified the responsible brain areas. They have found that the processing of olfactory and visual stimuli remains intact across a wide age range, and the use of strong stimuli does not lead to a superadditive multisensory integration. However, removing a stimulus modality activates additional brain areas that are related to attention, memory, and the search of the missing stimulus. Therefore, it is important to carefully design multimodal sensory experiments and control for cognitive expectancy effects that could affect the results.

Summary: EEG slow waves play a crucial role in regulating essential processes such as learning and sensory disconnection. They may involve complex interactions within and between cortical and subcortical structures. Moreover, simultaneous EEG-fMRI recordings show that slow waves are associated with specific hemodynamic changes in different brain regions.

Summary: This study examines the mathematical basis and signal-processing properties of the Difference of Gaussians model in the human visual cortex, finding that the DC-balanced model is preferred over the DC-biased model. Through fMRI mapping, it is suggested that V1 pRFs may be organized as bandpass filters, allowing for the separation of stimulus contrast and luminance.

Summary: Through a study involving survey, it was found that olfactory loss is a reliable predictor of COVID-19, with smell loss being significantly more pronounced in COVID-19 positive participants. Smell loss during illness is identified as the best predictor of COVID-19 among those with symptoms of respiratory illness.

Summary: The study found that besides changes in the olfactory cortex after head trauma, other cortical areas play a significant role in olfactory impairment. The neural responses and connectivity in higher-order areas have complex relationships with olfactory perceptual function, which can help distinguish functional anosmia from normosmia.

Summary: Transcutaneous vagus nerve stimulation (tVNS) is gaining interest in basic, translational, and clinical research due to its non-invasive nature. Future studies need to focus on reporting practices, stimulation parameters, and participant safety to advance the field. Additionally, advancements in animal research may have implications for the application of tVNS in humans.

Summary: Participants with and without obesity experiencing COVID-19 reported similar declines in chemosensory functions. However, those with obesity showed a greater prevalence of non-chemosensory symptoms. Self-reported chemosensory symptoms were found to be equally predictive of COVID-19 infection in both groups, suggesting the potential of remote symptom collection in clinical settings with limited observations.

Summary: Sudden smell loss is a specific early symptom of COVID-19. A longitudinal survey on smell function and recovery reveals that while smell ability improves for many individuals during acute COVID-19, the prevalence of parosmia and phantosmia increases over time. Persistent smell impairment may be a key marker of long-term COVID-19 illness.

Summary: Vagus nerve signals from the gut to brain carry information about nutrients and drive food reward. Non-invasive vagus nerve stimulation (nVNS) via a branch innervating the ear is a potential treatment for obesity. This study compared different ear positions for nVNS and explored the effects of nVNS during hungry and post-prandial states.
