Recently, Professor Surjo R. Soekadar outlined current and upcoming applications of brain-computer…
Researchers at Durham University are working on a new infrared light therapy that might have the potential to help people with dementia. In the approach, people wear a specially adapted helmet which delivers infrared light deep into the brain for six-minutes per treatment. This stimulates mitochondria that generate most of the chemical energy needed to power the biochemical reaction in the…
Beige is considered a calming paint color, and scientists have new evidence that beige fat has a similar impact on the brain, bringing down the inflammation associated with the more common white fat and providing protection from dementia. They have found that beige fat cells, which are typically intermingled with white fat cells in the subcutaneous fat present on “pear shaped” people, mediate…
Artificial intelligence (AI) could match the impact of PACS on radiology.

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…
Neuroscientists at Emory University School of Medicine have discovered a focal pathway in the brain that when electrically stimulated causes immediate laughter, followed by a sense of calm and happiness, even during awake brain surgery. The effects of stimulation were observed in an epilepsy patient undergoing diagnostic monitoring for seizure diagnosis. These effects were then harnessed to help…
A new neurostimulator developed by engineers at the University of California, Berkeley, can listen to and stimulate electric current in the brain at the same time, potentially delivering fine-tuned treatments to patients with diseases like epilepsy and Parkinson's. The device, named the WAND, works like a "pacemaker for the brain," monitoring the brain's electrical activity and…
Traumatic experiences can become deeply entrenched in a person's memory. How can fears following a traumatic event be reduced in the long term and prevented from becoming a permanent stress-related disorder? Researchers at the Mainz University Medical Center have recently shed new light on these questions. The key to their approach lies in firmly anchoring new, positive experiences in the…
A world where machines can be controlled by thought alone – such is the promise of so-called brain-computer interfaces (BCI). BCIs are both hardware and software communication systems that read brain and nerve signals, convert those into electrical signals and translate human thoughts into machine commands. Developers of BCIs rely on artificial intelligence, neural network models and big data…
The first patient in a multicenter pivotal trial using focused ultrasound to address the major motor symptoms of Parkinson’s disease has been treated at Weill Cornell Medicine and NewYork-Presbyterian/Weill Cornell Medical Center in New York.
