Summary: The study shows that novelty has an impact on brain circuits, particularly the interactions between the hippocampal-VTA circuit and cortical networks. Following exposure to novelty, functional coupling is enhanced between the right anterior hippocampus and VTA, with distinct patterns of post-novelty functional coupling enhancements observed in the anterior hippocampus and VTA, targeting task-relevant regions and large-scale networks respectively.

Summary: Eye contact is crucial for the formation and maintenance of social relationships, particularly in parent-child bonds. However, the exact neural and affective mechanisms of eye contact in parent-child relationships are still unknown. This study introduces a task to evaluate parents' neural and affective responses to prolonged direct and averted gaze from their own child, an unfamiliar child, and an unfamiliar adult. The results indicate that prolonged direct gaze improves parents' mood and feelings of connectedness, especially with unfamiliar targets. Neuroimaging results reveal increased brain activity in certain regions when parents see their own child compared to seeing an unfamiliar child or adult. These findings highlight the importance of prolonged eye contact in affiliative processes and provide initial insights into its neural correlates.

Summary: Primates in zoos can spontaneously categorize humans based on familiarity and show attentional bias towards unfamiliar human faces, possibly reflecting a novelty effect.

Summary: This paper reviews studies on sensory preconditioning in different animals and humans to determine how memory is integrated. The results show that memory integration can occur through chaining when stimuli are presented repeatedly or serially, while online integration occurs when stimuli are relatively novel or presented simultaneously.

Summary: The study found that painting content and complexity have an interactive influence on familiarity-novelty preference for aesthetic appreciation, especially between representational and abstract paintings. In addition, the preference for novelty is modulated by the level of art experience, particularly in the case of abstract paintings.

Summary: Research shows that people are better at understanding speech when it is masked by competing sounds if the speaker is familiar, indicating a correlation between familiar voices and enhanced processing in the brain. This study used fMRI to demonstrate that familiar voices can lead to an improvement in signal-to-noise ratio in cortical activity, particularly in the posterior temporal cortex. Experience-driven improvements in intelligibility are associated with enhanced multivariate pattern activity in the auditory cortex.

Summary: During recognition memory, coupled theta activity between the hippocampus and medial prefrontal cortex plays a key role in novelty discrimination, with monosynaptic connections identified as crucial for guiding behavior based on recognition memory.

Summary: Neurovascular alterations play a key role in many brain diseases and can be effectively observed and measured using MRI techniques. The current MRI sequences provide reliable markers for vascular dysfunction, but further research is needed to observe vascular changes at a finer scale.

Summary: A network-level model was constructed to analyze the activities of different cognitive types in various brain regions, revealing a functional dissociation between different components. The validity of the model was evaluated through meta-analyses, which confirmed the predicted order of activities in different brain regions.

Summary: Hippocampal impairments are associated with post-traumatic stress disorder (PTSD), particularly in individuals with increased threat sensitivity and arousal responses. This study found that individuals who showed high threat-related arousal had decreased hippocampal responses to threat, which were associated with PTSD symptoms.

Summary: Researchers have developed a two-dimensional fast line-scan approach that allows direct imaging of neuronal activity with millisecond precision, while maintaining high spatial resolution. This method was demonstrated in live mouse brain imaging, showing the sequential and laminar-specific propagation of neuronal activity along the thalamocortical pathway.

Summary: Novelty can enhance long-term memory, but this effect may be reduced in aging brain. In this study, researchers used functional MRI to investigate the neural mechanisms underlying the impact of novelty on memory in young and older adults. Age-related differences were found in neural activation patterns, suggesting that the effect of novelty on memory may decline with age.

Summary: This study investigates distortion compensation in the context of sub-millimeter 3DEPI data at 7T. B0 field-mapping and reversed-PE distortion correction techniques were applied and compared, and the results show that both techniques improve cortical alignment, with the reversed-PE approach achieving more substantial improvements.

Summary: High-resolution functional MRI studies have proven to be a powerful tool in probing the functional organization of the human cortex, with ongoing debate within the community regarding the use of gradient echo or spin echo based acquisition methods. Phase regression technique shows potential as a useful method in low signal-to-noise ratio studies such as high-resolution fMRI.
