How do brains remember decisions?

Mammal brains — including those of humans — store and recall impressive amounts of information based on our good and bad decisions and interactions in an ever-changing world. Now, in a series of new experiments with mice, scientists at Johns Hopkins Medicine report they have added to evidence that such “decision-based” memories are stored in […]

Researchers discover the Achilles’ heel of an aggressive brain cancer: Could antihistamine be a potential aid in defeating cancerous cells?

Glioblastoma is the most prevalent and also the most lethal type of brain tumour in adults, with no curative treatment currently available. Glioblastomas cannot be surgically completely excised, as the tumour cells are adept at invading tissues and spreading around the brain. In addition, glioblastoma cells are extremely resistant to existing drug therapies. For a […]

How our brain generates consciousness — and loses it

Medically-induced loss of consciousness (mLOC) during anesthesia is associated with a break-down of brain connectivity at the anatomical macro scale — across cortical areas — yet what role brain micro circuitry plays in LOC remains unclear. How does our brain generate our consciousness? And why do we lose it during anesthesia? Influential theories suggest that […]
