Chronic back pain linked to heightened sound sensitivity in the brain
People with chronic back pain process everyday sounds differently, and more intensely, than people without pain, according to…
Vectorized instructive signals in cortical dendrites
Sacramento, J., Bengio, Y., Costa, R. P. & Senn, W. Dendritic cortical microcircuits approximate the backpropagation algorithm. In…
Study reframes amygdala as the sophisticated learning arbiter
A Dartmouth study challenges the conventional view that the amygdala-the two-sided structure deep in the brain involved in…
Electroacupuncture relieves pain-induced anxiety through prefrontal neural circuits
Neuropathic pain, caused by injury or disease of the somatosensory nervous system, is a major clinical challenge and…
Brain immune cells drive persistent negative emotions after repeated binge drinking
New research has identified that neuroinflammation driven by microglia (immune cells in the brain) is a primary underlying…
Biomimetic brain modeling mirrors animal learning and neural dynamics
A new computational model of the brain based closely on its biology and physiology not only learned a…
Cognitive blocks drive the brain’s advantage over AI
Artificial intelligence may write award-winning essays and diagnose disease with remarkable accuracy, but biological brains still hold the…
