What Is a Visual Stream?

The dual stream model of the human and non-human primate visual systems remains Leslie Ungerleider's (1946-2020) most indelible contribution to visual neuroscience. In this model, a dorsal "where" stream specialized for visuospatial representation extends through occipitoparietal cortex, whereas a ventral "what" stream specialized for representing object qualities extends through occipitotemporal cortex. Over time, this model underwent a number of revisions and expansions.

Uric acid and acute kidney injury in high-risk patients for developing acute kidney injury undergoing cardiac surgery: A prospective multicenter study.

Purpose: It is unclear whether preoperative serum uric acid (SUA) elevation may play a role in the development of acute kidney injury (AKI) associated with cardiac surgery (CSA-AKI). We conducted a cohort study to evaluate the influence of preoperative hyperuricemia on AKI in patients at high risk for developing SC-AKI.

Design: Multicenter prospective international cohort study.

Physical and sexual abuse history in women seeking treatment at a psychiatric clinic for the homeless.

The rate of lifetime exposure to physical and/or sexual abuse among homeless women is very high, and the prevalence of depression, anxiety, and substance abuse is greater in this population than in the general population. The relationship between abuse and mental illness in homeless women is incompletely understood. Using multivariable logistic regression, the present study examines this relationship in a retrospective study of women seeking treatment at a psychiatric clinic for the homeless in Jacksonville, Florida.
