Hypoxia due to CHD linked to abnormal neurogenesis and impaired cortical growth
The subventricular zone (SVZ) in normal newborns' brains is home to the largest stockpile of neural stem/progenitor cells, with newly generated neurons migrating from this zone to specific regions of the frontal cortex and differentiating into interneurons. When newborns experience disruptions in cerebral oxygen supply due to congenital heart disease, essential cellular processes go awry and this contributes to reduced cortical growth. The preliminary findings derived from a preclinical model by a research team led by Children's National Health System point to the importance of restoring these cells' neurogenic potential, possibly through therapeutics, to lessen children's long-term neurological deficits.

Clinical trial for first-ever treatment of radiation necrosis
Radiation therapy saves countless lives, but in rare cases, it can cause a debilitating, long-term complication when used on the brain. Around three to five percent of patients who receive radiation for brain tumors, or arteriovenous malformations (AVM), develop radiation necrosis, where the brain tissue around the targeted lesion becomes injured and dies.

Out of tune: Mismatch of vascular and neural responses suggests limits of fMRI
In an article published online ahead of print on May 25, 2016 in Nature, investigators at the Medical University of South Carolina (MUSC) report that, during sensory stimulation, increases in blood flow are not precisely "tuned" to local neural activity, challenging the long-held view that vascular and local neural responses are tightly coupled.

Are stem-cell therapies for Parkinson's disease ready for clinical trials?
As stem cell-based therapies are moving rapidly towards clinical trials, treatments for Parkinson's Disease (PD), an incurable condition, may be on the horizon. A recent announcement of a Phase I/IIa clinical trial involving transplantation of stem cells into the first human subjects has raised hope among patients and sparked discussions in the research community. In a commentary published in the Journal of Parkinson's Disease, authors propose five key questions that should be addressed as this trial begins.

Lack of sleep tampers with your emotions
Cranky or grumpy after a long night? Your brain's ability to regulate emotions is probably compromised by fatigue. This is bad news for 30 percent of American adults who get less than six hours of sleep per night, according to the Centers for Disease Control and Prevention.

Can you think yourself into a different person?
For years she had tried to be the perfect wife and mother but now, divorced, with two sons, having gone through another break-up and in despair about her future, she felt as if she'd failed at it all, and she was tired of it. On 6 June 2007 Debbie Hampton, of Greensboro, North Carolina, took an overdose of more than 90 pills – a combination of ten different prescription drugs, some of which she'd stolen from a neighbour's bedside cabinet. That afternoon, she'd written a note on her computer: "I've screwed up this life so bad that there is no place here for me and nothing I can contribute." Then, in tears, she went upstairs, sat on her bed, swallowed her pills with some cheap Shiraz and put on a Dido CD to listen to as she died. As she lay down, she felt triumphant.
