Article Synopsis
  • * After analyzing six studies with 1,229 patients, it was found that reduced left ventricular ejection fraction (LVEF), atrial fibrillation (AF), left ventricular apical aneurysm (LVAA), and pacemaker use significantly elevate the risk of stroke, while anticoagulation therapy appears to reduce the likelihood of having a stroke.
  • * The researchers conclude that certain heart-related conditions are linked to higher AIS risk in CD patients, suggesting a need for more randomized studies to develop effective prevention strategies for these individuals.

Visual perceptual learning plays a crucial role in shaping our understanding of how the human brain integrates visual cues to construct coherent perceptual experiences. The visual system is continually challenged to integrate a multitude of visual cues, including form and motion, to create a unified representation of the surrounding visual scene. This process involves both the processing of local signals and their integration into a coherent global percept.

It was with the promise of rendering an experimental approach to consciousness that psychology started its trajectory as an independent science more than 150 years ago. Here, we will posit that the neurosciences were instrumental in leading psychology to resume the study of consciousness by projecting an empirical agenda for the future. First, we will start by showing how scientists were able to venture into the consciousness of supposedly unconscious patients, opening the door for the identification of important neural correlates of distinct consciousness states.
