Summary: This study found that the ability to imagine odours is associated with food cravings and weight gain. Through an observational study on 45 adults, it was discovered that the ability to imagine odours is correlated with the intensity of food cravings, which in turn promotes adiposity and leads to weight gain over time.

Summary: Hypnotic suggestions can induce a variety of perceptual experiences, including hallucinations. Visual hypnotic hallucinations differ from regular mental images in terms of their automaticity, vividness, and realism. Research suggests that the neural signatures distinguishing hypnotically hallucinated faces from imagined faces lie in the right hemisphere of the brain.

Summary: Individuals experience different levels of vividness in their visual mental images. A study with 117 healthy participants found that those with congenital aphantasia, a condition characterized by absent or near-absent visual imagery, had slower response times in both imagery and perceptual tasks, but similar levels of accuracy compared to other groups. These findings support the hypothesis that congenital aphantasia primarily involves a deficit of phenomenal consciousness.

Summary: The study investigates the spatiotemporal dynamics of self-generated imagery using electroencephalography and functional magnetic resonance imaging. The results show overlapping neural signatures of cue-induced and self-generated imagery but with significantly different sensitivities to the two types of imagery.

Summary: Recent research suggests that imagery is comparable to a weaker version of visual perception. This study provides evidence from five independent experiments that perception and imagery are supported by fundamentally different mechanisms. Perception is largely formed through increased excitatory activity, while imagery is supported by modulating nonimagined content.

Summary: Auditory and visual evoked potentials (EP) can be used to monitor cognitive changes after concussion. Previous studies have shown both decreases and increases in EP after injury. This study examined auditory and visual EP in female piglets subjected to different levels of head rotations. The results showed decreased auditory EP and brain activity in the control group, increased auditory EP in the single rotation group, and decreased visual EP in the repeated rotation group. The findings suggest that injury biomechanics play a role in determining neurofunctional deficits after concussion.

Summary: The mid-latency P2p component mainly reflects perceived changes in numerical attributes, while earlier components are likely to be related to the physical characteristics of the stimuli. Short-term plastic mechanisms induced by numerosity adaptation may involve a relatively late processing stage of the visual hierarchy likely engaging cortical areas beyond the primary visual cortex.

Summary: In this study, it was found that neural representations of imagined images can still be present in humans even when they are shown conflicting images. Furthermore, there is semantic asymmetry between the neural representations of imagined and perceived images.

Summary: Previous studies have shown that bodily signals from internal organs are linked to various sensory-motor functions. A recent study found that voluntary actions are associated with the breathing cycle. This study investigated whether this breathing-action coupling is limited to voluntary body movements or if it also occurs in mental actions without overt bodily movement. The results showed that both imagined and overt actions are coupled with respiration, suggesting the involvement of the breathing system in the preparatory processes of voluntary actions.

Summary: The study shows that spatial information is widely coded in the high-level visual cortex during perception and imagery, with visual information being coded in both preferred and non-preferred regions of the HVC, supporting a distributed view of encoding.

Summary: Although research has shown similarities in function and neural mechanisms between imagery and perception, there are still noticeable differences in our experiences of the two. Studying the directional flow of information, different cortical layers in the primary visual cortex, and potential neural mechanisms of modulation versus excitation may help explain why imagery and perception feel distinct.

Summary: Greenway is a corridor in the city connecting natural elements and open spaces with functions such as leisure and recreation. The assessment of built greenways provides important construction experience and planning concepts. The research results show that continuous cycling paths, high security awareness, open landscapes, and rich human activities evoke positive perceptions among local cyclists.

Summary: This study used immersive virtual reality to investigate how individual tendencies to process and represent visual information contribute to eye fixation patterns on previously inspected objects. The findings showed that participants also look back to relevant locations when they are free to move in 3D space, and this behavior depends on individual differences in visual object imagery abilities.

Summary: This study proposes a multi-penalized state-space model for analyzing unobserved dynamics, using a data-driven regularization method. Novel algorithms are developed to solve the model, and a cross-validation method is introduced to evaluate regularization parameters. The effectiveness of this method is validated through simulations and real data analysis, enabling a more accurate exploration of cognitive brain functions.
