Cortex-wide characterization of decision-making neural dynamics during spatial navigation.

Decision-making during freely moving behaviors involves complex interactions among many cortical and subcortical regions. However, the spatiotemporal coordination across regions to generate a decision is less understood. Using a head-mounted widefield microscope, cortex-wide calcium dynamics were recorded in mice expressing GCaMP7f as they navigated an 8-maze using two paradigms.

Elucidation of the genetic architecture of water absorption capacity in hard winter wheat through genome wide association study.

Water absorption capacity (WAC) influences various aspects of bread making, such as loaf volume, bread yield, and shelf life. Despite its importance in the baking process and end-product quality, its genetic determinants are less explored. To address this limitation, a genome-wide association study was conducted on 337 hard wheat (Triticum aestivum L.

Addressing Racial Disparities in the Hypertensive Disorders in Pregnancy: A Plan for Action from the Preeclampsia Foundation's Racial Disparities Task Force.

Hypertensive disorders of pregnancy (HDP) are among the leading causes of maternal mortality in the United States, with Black women and birthing people disproportionately having higher HDP-related deaths and morbidity. In 2020, the Preeclampsia Foundation formed a national Racial Disparities Task Force (RDTF) to identify key recommendations to address issues of racial disparities related to HDP. Recommendations are centered around the Foundation's three pillars: Community, Healthcare Practice, and Research.

Highly restrictive and directional penetration of the blood cerebral spinal fluid barrier by JCPyV.

The human polyomavirus JCPyV is an opportunistic pathogen that infects greater than 60% of the world's population. The virus establishes a persistent and asymptomatic infection in the urogenital system but can cause a fatal demyelinating disease in immunosuppressed or immunomodulated patients following invasion of the CNS. The mechanisms responsible for JCPyV invasion into CNS tissues are not known but direct invasion from the blood to the cerebral spinal fluid via the choroid plexus has been hypothesized.
