Neuroscientists in the UK and USA have collaborated to make “a spectacular discovery” - for the first time in human studies - of how memories are formed and new learning takes place. A collaboration between Matias Ison and Rodrigo Quian Quiroga at the Centre for Systems Neuroscience University of Leicester, UK, and Itzhak Fried at Ronald Reagan UCLA Medical Center, USA, revealed how a neuron in the brain instantly fired differently when a new memory was formed.

In this video from the Stroke Live Course (SLICE, 7-9 September 2015, Nice, France), stroke unit teams from hospitals across the globe showcase their everyday experience with stroke patients.

New therapies are on the horizon for individuals paralysed following spinal cord injury. The e-Dura implant developed by EPFL scientists can be applied directly to the spinal cord without causing damage and inflammation.

A major breakthrough in the development of stem cell-derived brain cells has put researchers on a firm path towards the first ever stem cell transplantations in people with Parkinson’s disease. A new study presents the next generation of transplantable dopamine neurons produced from stem cells. These cells carry the same properties as the dopamine neurons found in the human brain.

Traditionally, induced hypothermia has been used as a tool to protect brain cells in the presence of oxygen deprivation. But physicians are now considering how hypothermia may help to prevent brain damage due to stroke. Maxim Hammer, assistant professor in the Department of Neurology, University of Pittsburgh Medical Center, USA, discusses how hypothermia, when combined with other therapies, may be effective in decreasing mortality and improving outcomes for patients with brain swelling brought on by stroke.

Adriane Randolph is shaping the future of brain-computer interface as director of the BrainLab at Kennesaw State University (KSU) and as a faculty member of KSU’s Coles College of Business. At the KSU BrainLab, she is working to discover impactful solutions for brain-computer interfaces by uncovering the underlying characteristics that affect users’ control. Here is Randolph’s featured talk at TEDxCentennialParkWomen.

Georgia Tech researchers have created a mechanical device intended to help stroke victims. Their functional MRI-compatible hemiparesis rehab device creates a long latency stretch reflex at the exact time as a brain signal.

With the largest ever research grant from Parkinson’s UK, researchers at the Oxford Parkinson’s Disease Centre are currently recruiting people with Parkinson’s disease that have been diagnosed in the last three years or are a brother or sister of someone with Parkinson’s disease from a population base of the Thames Valley for the Parkinson’s Monument Discovery Project.

At the Rehabilitation Institute of Chicago a recent study examined the effectiveness of using Navigated Brain Stimulation combined with upper limb rehabilitation to improve arm and hand use after stroke. Navigated Brain Stimulation is a form of non-invasive brain stimulation, and when used repetitively (one stimulation per second) over the non-injured side of the brain, it has been shown to reduce the excessive inhibitory drive that the non-injured side of the brain delivers to the injured side. Using new technology from Nexstim, the trial signalled a potential breakthrough in the treatment of stroke related injury, as well as benefitting many of those who received Navigated Brain Stimulation.

Josh Hirsch (Massachusetts General Hospital, USA), Philip M Meyers (Columbia University, USA) and Mahesh V Jayaraman (Rhode Island Hospital, USA) discuss the ever-developing field of neurointerventional surgery. In this podcast they talk about evidence-based medicine for cerebrovascular interventions, developing clinical guidelines and technical standards and research. The podcast is hosted by the BMJ.

Roger Ordidge, chair of Imaging Science at the University of Melbourne, Australia speaks in this video about a new PET/CT scanner located in the Melbourne Brain Centre and how it might help people with multiple sclerosis. He says that the PET/CT scanner can detect radiopharmaceuticals in the body at 1,000th of the concentration than MRI.

A woman in The Netherlands, in a pioneering surgery, has received a 3D printed skull implant. Bon Verweij, University Medical Center in Utrecht, The Netherlands, who led the operation is quoted as saying: “Implants used to be made by hand in the operating theatre using a sort of cement which was far from ideal. Using 3D printing we can make one to the exact size. This not only has great cosmetic advantages, but patients’ brain function often recovers better than using the old method.”

 

Flying through inner space

Carl Zimmer writes in National Geographic about charting the brain now in ways that were impossible just a few years ago. "Out of these surveys, an interesting new way to look at the brain is emerging. Call it the brain fly-through. The brain fly-through only became feasible once scientists started making large-scale maps of actual neurons in actual brains. Once they had those co-ordinates in three-dimensional space, they could programme a computer to glide through it. The results are strangely hypnotic." 

The video below is by Adam Gazzaley of the University of California at San Francisco, USA, and his colleagues, who have made it possible to fly through a representation of a thinking human brainas it thinks. The video was captured using MRI scanning, diffusion tensor imaging, and an EEG cap.

Charles M Eichler, professor of Surgery Division of Vascular Surgery, University of California, San Francisco, discusses patients with carotid stenosis and ipsilateral "silent" infarcts. This video is from the series: UCSF Vascular Surgery Symposium.

This video is related to the scientific publication: "Blood flow clustering and applications in virtual stenting of intracranial aneurysms" by Steffen Oeltze (department of Simulation and Graphics, faculty of Computer Science, University of Magdeburg, Germany) et al. The blood flow in a saccular side-wall aneurysm has been simulated based on the vascular morphology extracted from patient-individual data. The resulting flow data is often visualised by a dense and cluttered set of streamlines. Clustering the streamlines and computing cluster representatives reduces visual clutter and exposes characteristic flow structures. The resulting flow summary benefits the assessment of aneurysmal haemodynamics. If a virtual stent is deployed and the simulation is repeated, a comparison of the flow summaries supports a prediction of the treatment success.

A  new treatment for multiple sclerosis and the result of over three decades of research in Cambridge University, UK, was approved on the 17 September by the EU agency responsible for regulating new drugs. The drug, lemtuzumab (brand name Lemtrada), was previously called Campath-1H ("Cambridge Pathology 1st Human") and is indicated for the treatment of multiple sclerosis. This video explores the history of Campath-1H.

This video from UCLA Medical Center features, Paul Vespa, director of neurocritial care at Ronald Reagan UCLA Medical Center, Los Angeles, USA, and EVA, the neurointensive care unit’s “executive virtual attending” physician. NeuroNews is inviting views from experts on the use of robotic technology in patient care.

In the age of 24/7 connectivity, the video shows how the department, which introduced a remote-presence robot into its neurological intensive care unit in 2005, now welcomes the first robot able to navigate the hospital on its own.

NeuroNews would like to invite physicians to share their views on the increasing use of telepresence robots that aid in meeting intensive care needs. Does such an arrangement set a new frontier in patient safety? Is there a loss in the face-to-face interaction between doctor and patient? Write in with your comments at the end of the story.
