Researchers light-up mouse brain, revealing previously hidden areas susceptible to opioids

New work shows that kappa opioid receptors actually are distributed widely throughout the brain. The researchers made this discovery after lighting up the brains of mice using a technique called CLARITY followed by three-dimensional (3D) fluorescent im…

Former NFL players may not suffer more severe cognitive impairment than others, study indicates

Even though repeated hits to the head are common in professional sports, the long-term effects of concussions are still poorly understood. While many believe that professional athletes who experience multiple concussions will end up with severe cogniti…

DNA repair supports brain cognitive development

Researchers showed that na enzyme functions in genome maintenance by preventing double-stranded breaks in DNA during brain development in mice. In mice lacking this enzyme, these breaks occurred during epigenetic regulation of gene expression in the de…

Link between sleep apnea and increased risk of dementia

A new study by Monash University has found that obstructive sleep apnea (OSA) has been linked to an increased risk of dementia.

Sleep loss hijacks brain’s activity during learning

Sleep is crucial for consolidating our memories, and sleep deprivation has long been known to interfere with learning and memory. Now a new study shows that getting only half a night’s sleep – as many medical workers and military personnel often do – h…

Breakthrough discovery on brain cortex functionality

A team of researchers from UTSA’s Neurosciences Institute is challenging the historical belief that the organization of the cortical circuit of GABAergic neurons is exclusively local.

Research identifies ‘volume control’ in the brain that supports learning and memory

A ‘molecular volume knob’ regulating electrical signals in the brain helps with learning and memory, according to a new study. The finding could help researchers in their search for ways to manage neurological disorders, including Alzheimer’s disease, …

Glioblastoma nanomedicine crosses into brain in mice, eradicates recurring brain cancer

A new synthetic protein nanoparticle capable of slipping past the nearly impermeable blood-brain barrier in mice could deliver cancer-killing drugs directly to malignant brain tumors, new research shows.

Backup mechanism removes cellular debris from the brain

Microglia — the brain’s immune cells — play a primary role in removing cellular debris from the brain. A research team has found that another kind of brain cell, called astrocyte, is also involved in removing debris as a backup to microglia.

Fish give insight on sound sensitivity in autism

Scientists used zebrafish that carry the same genetic mutations as humans with Fragile X syndrome and autism, and discovered the neural networks and pathways that produce the hypersensitivities to sound in both species.
