Long-term or "complicated" grief activates neurons in the reward centers of the brain, possibly giving these memories addiction-like properties. Their research is currently available in the journal's online edition.
Researchers have now used sophisticated new imaging technology to identify a chemical messenger that helps neurons manage brain communicates with neurons, enabling them to adjust their sensitivity to incoming signals to facilitate learning and memory.
Patients who suffer from hard-to-treat brain intracranial aneurysms, traditionally undergo an endovascular procedure which involves injecting coils and stents through a catheter into the aneurysm sac.
