In patients with hoarding disorder, parts of a decision-making brain circuit under-activated when dealing with others’ possessions, but over-activated when deciding whether to keep or discard their own things.
Neuroscientists have believed that three brain regions are critical for self-awareness: the insular cortex, the anterior cingulate cortex, and the medial prefrontal cortex. Patient R is helping a research team show that self-awareness is more a product of a diffuse patchwork of pathways in the brain—including other regions—rather than confined to specific areas.
Researchers discover the activity of two specific neuron types, somatostatin and parvalbumin neurons, correlates with foraging decisions in mice.
Brain training programs work, but only for practiced tasks, researchers report.
The brain displays a similar pattern of activity during dreaming as it does during a psychedelic trip, a new study reports.
A new study reports people who multitask using several media devices at the same time have lower gray matter density in the ACC.
Researchers use optogenetics to stimulate the anterior cingulate cortex and lessen pain in mice.
A new study reports researchers have identified two groups of neurons which appear to play key roles in social interaction.
A new study reports of a biological basis as to why some people are quicker to learn than others.
