According to the Attention to Memory (AtoM) model, dorsal parietal cortex (DPC) mediates top-down attention processes guided by retrieval goals, whereas ventral parietal cortex (VPC) mediates bottom-up attention processes captured by the retrieval output or the retrieval cue. This model also hypothesizes that the attentional functions of DPC and VPC are similar for memory and [...]
As we age, our brains change quite dramatically and shrinking in size and changing in composition. We conducted a study to examine one rather overlooked element of this changing composition, mainly the idea that myelin—the sheaths around our nerve cells keeping everything running smoothly—degenerate as we age. In order to study this we used diffusion [...]
