Article Synopsis
- Acute stress affects how we remember not just individual emotional events but also the contextual details surrounding them, with distinct neural processes involved for each type of memory.
- Stressed participants showed increased brain activation in areas linked to item memory retrieval, but reduced activation for recalling unpleasant contextual details.
- These findings highlight how stress can alter memory processing in different ways, suggesting potential implications for understanding stress-related disorders.
Claustrum volumes are lower in schizophrenia and mediate patients' attentional deficits.

Background: While the last decade of extensive research revealed the prominent role of the claustrum for mammalian forebrain organization, i.e., widely distributed claustral-cortical circuits coordinate basic cognitive functions such as attention, it is poorly understood whether the claustrum is relevant for schizophrenia and related cognitive symptoms.

When linked with traditional paleoecological methods, analysis of molecular biomarkers can yield new insights into the roles of herbivores and other animals in long-term ecosystem dynamics. We sought to determine whether fecal steroids in lake sediments could be used to reconstruct past ungulate use and dominant taxa in a small catchment in northern Yellowstone National Park.

During 2022-2023, a total of 7 US jurisdictions (5 states and 2 cities) participated in prospective or retrospective testing of wastewater for poliovirus after a paralytic polio case was identified in New York state. Two distinct vaccine-derived poliovirus type 2 viruses were detected in wastewater from New York state and New York City during 2022, representing 2 separate importation events.

- - Despite significant research on the claustrum's role in the mammalian brain, studies on its connections in humans are limited due to its complex anatomy and challenges in imaging techniques.
- - The study used deep-learning segmentation and diffusion-weighted imaging (DWI)-based tractography on two large groups of healthy adults to explore claustrum connectivity.
- - Results showed consistent and replicable connections between the claustrum and various brain regions across different subjects, enhancing the understanding of claustrum connectivity and its implications for health and disease.
