The perception of objects is a challenging task that requires recognizing visual elements and integrating them into a whole. While human vision prioritizes attention to the overall configuration, data from other species suggests this bias towards global form perception is not universal. Studies with pigeons indicate preferential attention to local details when both local and global information may be diagnostic, but studies with other bird species are more limited.

The advancements in cardiovascular imaging over the past two decades have been significant. The miniaturization of ultrasound devices has greatly contributed to their widespread adoption in operating rooms and intensive care units. The integration of AI-enabled tools has further transformed the field by simplifying echocardiographic evaluations and enhancing the reproducibility of hemodynamic measurements, even for less experienced operators.

Background: Neuron loss exceeds tau tangle formation (Gomez-Isla et al. 1997) and p-tau vulnerability differs by layer and subfield in entorhinal cortex (Llamas-Rodriguez et al., 2022).

However, most objective everyday function measures are difficult to administer and have not been validated against biomarkers of Alzheimer's disease (AD) neuropathology. This study evaluated the neuroimaging correlates of a highly sensitive, ecologically valid, and easily implementable performance-based test of function called the Virtual Kitchen Challenge (VKC).

This study examined whether inefficient reaching, touching, and extra movements (i.e.
