Illustration of the brain. Credit: Capillary Technologies. Experiencing a frightening incident is likely something you will always remember. Why does it remain with you when other kinds of events become increasingly hard to remember with time? A mechanism for the formation of fear memories in the amygdala, the emotional center of the brains, has been identified...
Anxiety and other dysfunctional mental states are related to high levels of BETA brainwave activity. Credit: Steven Johnson If you or somebody you know experiences feelings of anxiety, mood swings, mild depression, panic attacks, or obsessive thoughts, this article could be what you have been searching for. Any dysfunctional mental state often results from a...
Much of the electrical activity in the brain looks like noise and is not associated with reactions to any particular stimuli. The scientists found that there was structure in the noise that could reveal the state of attentiveness in the brain. In this model of brain activity in the monkey visual cortex, the overall...
DETI mapping results from the brain of a person viewing one of the stimuli used in the experiment (far left). The central column shows a flattened topographical map of the electrodes over the back of the head, illustrating the variation of DETI maps at each electrode across that scalp region. On the right-hand side,...
Electroencephalography (EEG), a technique for noninvasively measuring the electrical activity of the brain. Credit: iStoock Researchers raise concerns about the possible social, moral, and legal repercussions of technology's close relationship with the human brain. However, it may sound like a cyborg future where people can communicate with and control other people's external technological gadgets by using...

Amyloid plaques are aggregates of misfolded proteins that form in the spaces between nerve cells. Credit: Juan Gaertner New photo-oxygenation catalyst targets amyloid structure, enlists brain immune system cells. A small, light-activated molecule lately evaluated in mice corresponds to a brand-new strategy to eliminating clumps of amyloid protein located in the brains of Alzheimer's disease patients....
The level to which the brain's wiring aligns with its activity patterns can differ with sex and age and could be hereditary, proposes research published by Weill Cornell Medicine investigators. The study finds that this alignment might additionally have ramifications on cognition. The results released July 12 in Nature Communications assist shed light on one...
The ‘Third Thumb’ device being used to blow bubbles single-handedly. Credit: Dani Clode Using a robotic 'Third Thumb' can impact how the hand is represented in the brain, finds a new study led by University College London researchers. The group trained individuals to use an additional robotic thumb and found they could effectively carry out dextrous...
A set of brain signals known to assist memories form may additionally influence blood glucose levels, finds brand-new research in rats. Researchers at NYU Grossman College of Medicine discovered that a strange signaling pattern in the brain area called the hippocampus, connected by previous studies to memory development, likewise affects the metabolic process, the procedure...
