Human intelligence arises from coordinated brain networks

Researchers used neuroimaging and two adult datasets to test the Network Neuroscience Theory. They found that general intelligence reflects system-level organization and coordination across large-scale brain networks, with implications for development, injury and artificial systems.

Brain pressure can make neurons self-destruct

Researchers found that sustained physical pressure on the brain can trigger neurons to activate self-destruct programs. This irreversible neuron loss may explain sensory, motor and cognitive problems and suggests drug targets.

Attention cycles seven to ten times per second

Scientists found that human attention shifts in a steady rhythm about seven to ten times per second. This rhythm helped early humans notice danger but can make modern people more vulnerable to phone and computer distractions.

More brain activity in OCD during a sequence task

A Brown University study found that people with obsessive-compulsive disorder (OCD) show extra brain activity when doing a demanding sequence task in an MRI. The findings point to new brain targets that might improve transcranial magnetic stimulation (TMS) treatment.

Computerized games help the brain after injury

New research shows that adults with traumatic brain injuries who completed computerized cognitive games had changes in brain structure and better scores on tests of processing speed, attention and memory.

Scientists identify brain network behind Parkinson's symptoms

Researchers found a brain network called SCAN that appears central to core Parkinson's problems. In a small trial, noninvasive stimulation directed at SCAN improved symptoms more than stimulation of nearby brain areas.

Shrews shrink organs to survive winter

Eurasian common shrews shrink their brains and other organs in winter, a seasonal change called Dehnel’s phenomenon. Two new studies link genetic and chromosomal changes to this shrinking and to the regrowth that occurs in spring.

Possible virus link to ALS-like disease found in mice

Researchers studied a mouse strain called CC023 and found that a viral infection produced lasting nerve damage and symptoms similar to ALS. The strain may help find early biomarkers and test new treatments for sporadic ALS.

Brain circuits for facial expressions

Researchers found a network of brain and facial muscle circuits that generate expressions. Using fMRI in macaque monkeys, they mapped brain areas and showed regions act together with different timing and possible clinical uses.

New PET study links brain markers in Parkinson’s disease

Researchers used PET scans to compare two brain markers — dopamine transporters and synaptic density — in people with Parkinson’s and healthy volunteers. The study shows the usual link between markers breaks down in Parkinson’s.

Brain differences in WTC responders with PTSD

New imaging research of World Trade Center responders finds measurable brain structure differences linked to long-term PTSD. Researchers used gray-white contrast (GWC) MRI and other markers to distinguish responders with and without PTSD.

Light tool measures activity inside living brain cells

Researchers developed a bioluminescent calcium sensor called CaBLAM to record activity inside living brain cells without external light. The tool works in mice and zebrafish and enables long recordings that avoid damage from bright light.

Hub cells in the brain keep the body clock on time

Researchers used a new computational method called MITE to map how cells in the suprachiasmatic nucleus (SCN) talk to each other. They found a small group of hub cells that are essential for network synchrony and for the body clock.
