The effects of ongoing distraction on the neural processes underlying signal detection.

Distraction can impede our ability to detect and effectively process task-relevant stimuli in our environment. Here we leveraged the high temporal resolution of event-related potentials (ERPs) to study the neural consequences of a global, continuous distractor on signal-detection processes. Healthy, young adults performed the dSAT task, a translational sustained-attention task that has been used across different species and in clinical groups, in the presence and absence of ongoing distracting stimulation.

[Burden among caregivers of patients with Parkinson disease].

Background: Parkinson disease (EPI) patients often require being assisted by others. These caregivers are exposed to a decrease in their quality of Ufe.

Aim: To explore Parkinson disease patient features associated with a greater burden among their caregivers.
