Delayed-Onset White Matter Lesions on Brain MRI in Recurrent Non-cerebral Plasmodium falciparum Imported Malaria Without Neurological Symptoms.

malaria affects millions of people in certain regions of the world, with neurological involvement and/or cerebral malaria as potential manifestations. Brain magnetic resonance imaging (MRI) abnormalities have been well-documented in cerebral malaria. However, MRI abnormalities in non-cerebral malaria, especially in neurologically asymptomatic patients, are not well understood and have been less frequently reported, especially in non-endemic regions.

Anterior cingulate cortex supports effort allocation towards a qualitatively preferred option.

The anterior cingulate cortex (ACC) is known to be involved in effortful choice, yet its role in cost-benefit evaluation of qualitatively different rewards (more/less preferred), beyond magnitude differences (larger/smaller), is poorly understood. Selecting between qualitatively different options is a decision type commonly faced by humans. Here, we assessed the role of ACC on a task that has primarily been used to probe striatal function in motivation.
