Neurosurgical operating theatre

Neurosurgery taught via Virtual Reality

Virtual Reality (VR) technology is aiding trainee surgeons to practise complex procedures in a simulated setting, rather than learning skills on real patients. VR is also helping to demystify neurosurgery in that it enables medical students and patients to ‘enter’ and experience a neurosurgical operating theatre. Alex Alamri, a trainee neurosurgeon at Barts Health NHS Trust in London, UK,…

Obsessive compulsive disorder

Targeted deep brain stimulation reduces OCD symptoms

The debilitating behaviours and all-consuming thoughts which affect people with severe obsessive compulsive disorder (OCD), could be significantly improved with targeted deep brain stimulation, according to the findings of a new study. OCD is characterised by unwanted intrusive thoughts (obsessions) and repetitive stereotyped behaviours (compulsions- sometimes called rituals) and often means…

No way to stop the waves of change, but radiologists can learn to surf

Technological change is a major part of change management in radiology and it is inevitable. Artificial intelligence (AI) has slipped into every area of life including the hospital, and is already making decisions in radiology systems. The good news is that radiologists could win on two fronts, provided they play their cards well, a leading USA radiologist told delegates at a recent congress in…

Waves move across the human brain to support memory

Biomedical engineers at Columbia Engineering have discovered a new fundamental feature of brain oscillations: they actually move rhythmically across the brain, reflecting patterns of neuronal activity that propagate across the cortex. The coordination of neural activity across widespread brain networks is essential for human cognition. Researchers have long assumed that oscillations in the brain,…

The science behind Michael Jackson’s dance moves

When was the last time you watched a Michael Jackson music video? If your answer is “never” or “not for quite a while,” you are really missing a treat. According to Rolling Stone, “No single artist … shaped, innovated or defined the medium of ‘music video’ more than Michael Jackson.” Back in the 1980s and early 1990s, MTV had only one format—music videos—and that genre…

Researchers find missing immune cells that could fight glioblastoma

Glioblastoma brain tumors can have an unusual effect on the body's immune system, often causing a dramatic drop in the number of circulating T-cells that help drive the body's defenses. Where the T-cells go has been unclear, even as immunotherapies are increasingly employed to stimulate the body's natural ability to fight invasive tumors. Now researchers have tracked the missing T-cells in…
