UCLA Grad Slam winner sheds light on cerebellum ’s role in autism
Key takeawaysThe annual Grad Slam competition challenges graduate students to briefly explain their research in a clear and accessible way in front of an audience of non-experts.This year ’s winner, neuroscience doctoral candidate Melis Çakar, spoke about how activity in a brain structure called the cerebellum correlates with over-responsivity to sensory stimuli in people with autism spectrum disorder.Çakar beat out 52 other competitors and won $5,000; she will now represent UCLA at the UC-wide Grad Slam competition on May 3.Imagine you ’re trying to catch a ball or tie your shoes. It is your cerebellum, a part of y...

French-led team unveils 11.7 tesla MRI scans of human brain
A research group based in Saclay, near Paris, has taken the wraps off what it claims are the world's first MRI scans of the human brain in vivo taken at a field strength of 11.7 tesla. President Emmanuel Macron has congratulated the researchers on social media.
"The first images surpassed our expectations, giving after just four minutes, mind-blowing brain images without any artifacts, with superb tissue contrast and resolution, which represents a volume equivalent to a few thousand neurons," Denis Le Bihan, PhD, founding director of the NeuroSpin research facility and founder of Iseult Project of the French Alternative E...

PET scanner visualizes brain activity during cough
In this study, the researchers evaluated whether the experimental PET system could clarify brain activity during CiTA. This would allow clinicians to predict whether CiTA will be effective before attempting it in patients with brain lesions who have sustained damage to the regions related to cough control, they wrote.
The group enrolled 24 healthy patients who underwent separate O-15 water PET scans during four tasks: resting, voluntary cough, induced cough (where participants were induced by CiTA), and suppressed cough.
Participants were fitted with masks for cough measurements during two-minute PET scans. The tussive a...

MRI shows PTSD sufferers have smaller cerebellums
MRI shows that people with post-traumatic stress disorder (PTSD) have a cerebellum about 2% smaller than adults without the condition, especially in areas that influence emotion and memory, according to a study published January 10 in Molecular Psychiatry.
The cerebellum coordinates movement and balance and influences emotion and memory. But it's unclear whether a smaller cerebellum makes a person vulnerable to PTSD or whether PTSD shrinks this particular brain region, noted a team led by Ashley Huggins, PhD, of the University of Arizona in Tucson. (The study was conducted under the auspices of the lab of psychiatrist Ra...

PET reveals patterns underlying cognitive decline in patients with DLB
F-18 FDG-PET imaging in patients with dementia with Lewy bodies (DLB) has shown that brain hypo- and hypermetabolism may have different effects on cognition, according to a study published January 3 in npj Parkinson’s Disease.
The study is the first to show that these brain glucose metabolism patterns may independently affect cognitive decline and to clarify potential therapeutic targets in these patients, according to the authors.
“The present study suggests that DLB-hypo and DLB-hyper may be independent of each other and differentially affect the baseline and longitudinal cognitive function in patients with DLB,”...

Will losing weight help improve my balance? Ask the GP DR MARTIN SCURR
Balance is controlled by a part of the brain, the cerebellum, which receives information from your eyes, the balance mechanism of the inner ear, and something called the proprioceptive system. (Source: the Mail online | Health)
