The large-scale organization of shape processing in the ventral and dorsal pathways is dissociable from attention.

The two visual pathways model posits that visual information is processed through two distinct cortical systems: The ventral pathway promotes visual recognition, while the dorsal pathway supports visuomotor control. Recent evidence suggests the dorsal pathway is also involved in shape processing and may contribute to object perception, but it remains unclear whether this sensitivity is independent of attentional mechanisms that were localized to overlapping cortical regions. To address this question, we conducted two fMRI experiments that utilized different parametric scrambling manipulations in which human participants viewed novel objects in different levels of scrambling and were instructed to attend to either the object or to another aspect of the image (e.

Calcium-Sensing Receptor Antagonist NPS-2143 Inhibits Breast Cancer cell Proliferation, Migration and Invasion via Downregulation of p-ERK1/2, Bcl-2 and Integrin β1 and Induces Caspase 3/7 Activation.

Calcium-sensing receptor (CaSR) has been associated with breast cancer metastasis tothe bone. Targeting chemoattractant factors, such as calcium, that are released in response tobone resorption could prevent metastasis and induce apoptosis of cancer cells. In the presentstudy, we investigated the potential caspase 3/7 activation following treatment with a CaSRantagonist, NPS-2143, in breast cancer cells.
