New imaging method tracks brain’s elusive networks
A new system for high-density EEG helps with the imaging of the origin and path of both normal and abnormal neural activity

Neuroscientists Think They've Found a Previously Unknown Form of Neural Communication
Scientists think they've identified a previously unknown form of neural communication that self-propagates across brain tissue, and can leap wirelessly from neurons in one section of brain tissue to another – even if they've been surgically severed

Dynamic stimulation of the visual cortex allows blind and sighted people to ‘see’ shapes
A visual cortical prosthesis can restore sight by bypassing damage to the eyes and delivering visual information retrieved from a camera directly to the brain

Significant differences exist among neurons expressing dopamine receptors
Dopamine receptors have different molecular features and functions depending on their anatomical location within the striatum

How strong is your mental imagery? It might depend on how ‘excitable’ your neurons are
Highly excitable neurons in the visual cortex may reduce a person’s ability to imagine mental images

High density EEG produces dynamic image of brain signal source
Researchers combine machine learning, EEG, and new functional imaging technology to dynamically map a neural signal’s source and underlying brain networks

Origins of human language pathway in the brain at least 25 million years old
Studying auditory regions and brain pathways in humans, apes, and monkeys, researchers have identified a language pathway that interconnects the auditory cortex with frontal lobe regions

A gut-to-brain circuit drives sugar preference and may explain sugar cravings
In the intestines, signals of sugar ingestion travel to the brain, sparking an appetite for more sweet foods

Advanced, high-res MRI scans reveal link between cognitive abilities and ‘tree ring’ layers in the brain
Object and facial recognition abilities are associated with the same brain area but are characterized by different depths of cortical layers, which form at the age each ability was acquired.

NIH BRAIN Initiative tool helps researchers watch neural activity in 3D
SCAPE microscopy, a new 3D imaging technique, allows a greater volume of brain tissue to be viewed in a much less damaging way to networks of living cells

The brain dictionary
Scientists have created an interactive map showing which brain areas respond to hearing different words

This is a 100 micron resolution magnetic resonance imaging (MRI) scan of an ex vivo human brain specimen
