Semantic maps in the human brain

The meaning of language is represented in regions of the cerebral cortex known collectively as the “semantic system”. However, little of the semantic system has been mapped comprehensively, and the semantic selectivity of most regions is still unknown. Here we systematically map semantic selectivity across the cerebral cortex using voxel-wise modeling of fMRI data collected…

A newly updated map of the human brain shows almost 100 areas

A newly updated map of the human brain may be the most accurate yet, helping solve over 100 years of arguments and showing nearly 100 areas that hadn’t been reported before. The first hints of the brain’s hidden geography emerged more than 150 years ago. In the 1860s, the physician Pierre Paul Broca was intrigued…

How the Brain Builds Memory Chains

Do you remember the first time you met your college classmate? You were probably nervous, talking a little too loudly and laughing a little too heartily. What else does that memory bring to mind? The lunch you shared later? The other classmates you met that night? Memories bring about memories, and as soon as you…

Introduction to Mu Waves

Brain-Computer Interfaces (BCI) are currently being pursued in several approaches by different researchers and people around the World. One approach is to measure the “Mu Rhythms”, or also known as “Mu Waves” from the sensorimotor area of one’s brain by registering an EEG signal. The Mu Waves are associated with the movement of the body –…
