Cooling cardiac arrest patients may mean better long-term brain function

(HealthDay)鈥擫owering the body temperature in patients resuscitated from cardiac arrest helps a broader group of people than previously believed, a new French study finds. For cardiac arrest patients with what’s called a “nonshockable” rhythm, cooling the body almost doubles the odds they’ll have good brain function if they survive, researchers Continue Reading

Sex-based differences in the development of brain hubs involved in memory and emotion

The amygdala and the hippocampus鈥攕tructures in the brain that are involved in emotion, learning, and memory鈥攈ave been found to play a role in a diverse range of disorders, such as attention-deficit/hyperactivity disorder (ADHD), anxiety, depression, and schizophrenia. Research investigating the development of these two structures has shown that differences in Continue Reading

Study identifies brain protein that could put the brakes on Alzheimer’s

University of California, Irvine biologists blazing new approaches to studying Alzheimer’s disease have made a major finding on combating inflammation linked to the disease. The School of Biological Sciences researchers’ discovery about the role of a protein called TOM-1 heralds a shift toward examining the molecular underpinnings of Alzheimer’s processes.

Is this brain cell your ‘mind’s eye’?

No-one knows what connects awareness鈥攖he state of consciousness鈥攚ith its contents, i.e. thoughts and experiences. Now researchers propose an elegant solution: a literal, structural connection. ‘Content circuits’ within the cortex are plugged into ‘switchboard circuits’ that allocate awareness, says the theory, via cortical cells called L5p neurons. Writing in Frontiers in Continue Reading

 A model for brain activity during brain stimulation therapy

Brain stimulation, where targeted electrical impulses are directly applied to a patient’s brain, is already an effective therapy for depression, epilepsy, Parkinson’s and other neurological disorders, but many more applications are on the horizon. Clinicians and researchers believe the technique could be used to restore or improve memory and motor Continue Reading

Exercise may slow brain deterioration in Alzheimer disease

(HealthDay)—Exercising may delay brain deterioration in people at high risk for Alzheimer disease, according to a proof-of-concept study published Sept. 17 in the Journal of Alzheimer’s Disease. Takashi Tarumi, Ph.D., from Texas Health Presbyterian Hospital in Dallas, and colleagues randomly assigned 70 patients with amnestic mild cognitive impairment (aMCI) to Continue Reading
