Neuroimaging – News and Features

News
Thiamine Derivative Boosts Physical Activity and Wakefulness
Thiamine derivatives, especially TTFD, have long been used to support energy, with recent studies suggesting they may enhance brain function. In rats, TTFD administration increased dopamine levels in the medial prefrontal cortex.

Stress Hormone Predicts Alzheimer’s Risk After Menopause
A UT Health San Antonio-led study shows elevated cortisol in midlife correlates with increased amyloid protein deposits in post-menopausal women’s brains. Researchers highlight stress hormone’s role in early Alzheimer’s risk.

News
Attention Triggers Deep Brain Activity Across All Senses
Yale-led research reveals that sensory input from vision, hearing, taste, and touch all stimulate shared deep brain regions, including the midbrain reticular formation and central thalamus. These areas play a vital role in consciousness.

News
Epiphanies Rewire the Brain for Better Learning
A new study shows that sudden insights, the classic “aha!” moments, spark brain changes that make learning stick. Using brain scans, researchers found these flashes of understanding activated memory regions and rewired visual processing areas.

News
Honey Bee Sleep Mirrors Human Brain Activity
A University of Trento study reveals that sleeping honey bees display synchronized brain activity similar to that of humans. Using imaging and neural modelling, researchers identified sleep-specific changes in sensory processing.

News
Dancing, Drumming and Decision-Making Aid Autism Interventions
A University of Delaware study found that autistic children aged 5–15 who engaged in whole-body movement activities saw improved executive functioning compared to those doing sedentary play. The gains were seen both in-person and via telehealth.

News
Detecting Parkinson’s Disease Years Before Symptoms With fMRI
Researchers have demonstrated that functional magnetic resonance imaging (fMRI) can detect early signs of Parkinson’s disease (PD) by analyzing brain activity linked to sensory impairments, such as smell and vision.

News
New MRI Technology Offers Better Diagnosis of Aortic Stenosis
Scientists have developed a new MRI technology that can help to diagnose a common heart problem more quickly and accurately than ever before.

News
How Amino Acid PET Imaging Is Changing Brain Cancer Diagnosis
A special imaging procedure, amino acid PET, can not only improve patient care but also advance research into the development of new treatment approaches in those with brain metastases.

News
New Microscopy Method Reconstructs Mammalian Brain Tissue
New light microscopy technique reveals complex molecular machinery alongside neural structures, helping researchers make sense of the complicated network of the brain.
