Sugar entering the brain during septic shock causes memory loss
During sepsis, the body sheds fragments of heparan sulfate, which crossed the blood-brain barrier and enters the hippocampus. The presence of heparan sulfate in the hippocampus may cause memory loss associated with septic shock.... Read More...
New insight into how obesity and insulin resistance can impair cognition
Adora2a mediating signaling in vascular endothelial cells disrupts the blood-brain barrier in obesity. This, researchers report, could be an underlying mechanism for synaptic plasticity and cognitive deficits in those with insulin resistance and obesity.... Read More...

Researchers discover crucial link between brain and gut stem cells
The insulin-like growth factor II gene plays a critical role in adult stem cell maintenance of both the intestine and the brain. Findings suggest IGF-2 is essential for multiple stem cell types, including those implicated in cognitive function and renewing the lining of the small intestine.... Read More...
Low-intensity ultrasound can change decision-making process in the brain
A study of macaque monkeys reveals low-intensity ultrasound can both generate and suppress signalling in the brain and modulate normal function. The ultrasonic stimulation alters counterfactual thinking, allowing the ability to decide upon a better alternative in decision-making tasks.... Read More...
Train your brain, change your brain
Neurofeedback training helps reinforce brain patterns associated with motor function while participants complete imaginary motor tasks. The findings may help in the rehabilitation for stroke and other disorders that compromise motor function. ... Read More...
