[Article] New diagnostic biomarkers offer ray of hope for Alzheimer's disease

Diagnosis for the Alzheimer’s disease continues to rely primarily on neuropsychological tests which can only detect the disease after clinical symptoms begin. In a supplement to the Journal of Alzheimer’s Disease, investigators report on the development of imaging-based biomarkers that will have an impact on diagnosis before the disease process is set in motion.

[Article] Condition once thought harmless alters brain function in elderly

A common condition called leukoaraiosis, once considered a harmless part of the aging process like gray hair, is actually a disease that alters brain function in the elderly, according to a new study

[Article] Intelligence : Brain size matters, but so do connections

Measuring humman intelligence may be controversial and oh-so-very-tricky to do. A new study, however, demonstrates a more rigorous way to see and measure differences in intelligence between individuals.

[Article] Memories on a Microchip

Researchers have been trying to make brain-like memory chips and some have found potential evidences of how to approach their ultimate goals in a step forward. In this article, there are some experimental cases introduced about the memory chips.

[Article] Lying eyes

Despite what you may have heard, you can’t tell if a person’s lying by watching their eyes. If you’re surprised, you’re not alone – I thought that theory made a lot of sense until I read this new study. As it turns out, the eye idea just doesn’t line up with the evidence.

[Article] Control a robot with thoughts from inside a brain scanner

By using an fMRI machine, which scans the brain and displays the activity in real time, paralyzed patients or people with locked-in syndrome can interact with the world using a surrogate body.

[Article] New Brain-Machine Spelling Device Could Help the Paralyzed Communicate

Scientists have found a way to use fMRI brain scans to read thoughts letter by letter in real time. They suggest their “brain-scanning speller” has potential for helping paralysed people who can’t move or speak, such as those with so-called “locked-in syndrome”, to have a conversation.

[Article] Brain structure helps guide behavior by anticipating changing demands

How much mental effort and attention are devoted to each task is usually determined in a split second and without conscious awareness. Now a study from Massachusetts General Hospital (MGH) researchers finds that a structure deep within the brain, believed to play an important role in regulating conscious control of goal-directed behavior, helps to optimize behavioral responses by predicting how difficult upcoming tasks will be.

[Technology] Deep Transcranial Magnetic Stimulation (TMS)

 Standard TMS coils are limited to activation of only cortical brain regions, up to a depth of about 1.5 cm. Hence when treating depression with a standard TMS system, the limbic system, which is related to mood regulation and is generally deeper than 1.5 cm, is only indirectly affected.

The unique technology of Brainsway Deep TMS System enables direct non-invasive activation of deep brain structures.  Deep TMS is a breakthrough in the search for a non-invasive approach for treating common brain disorders.
