As reported in Cell Stem Cell, the laboratory of

New findings will better help map out the brain’s speech regions. Credit: Adeen Flinker For 150 years, the iconic Broca’s area of the brain has been recognized as the command center for human speech, including vocalization. Now, scientists at UC Berkeley and Johns Hopkins University in Maryland are challenging this long-held assumption with new evidence

A recording site (grey dot) in a brain region responsible for social interaction showed clear differences in neural activity when the subject was talking to the life partner (green curve) vs. the physician (blue curve). Human speech comes in countless varieties: When people talk to close friends or partners, they talk differently than when they

Volume rendered Brain SPECT perfusion maps. The results are of a patient in the treated group suffering from left hemiparesis due to ischemic stroke that occurred 26 months prior to inclusion in the study. The brain perfusion maps (upper two images) show the infracted brain (deep blue color) involving the right antero-postero-lateral frontal, right superior-parietal

Brain activity during decision making. Credit: Penn Medicine During the last decade, commercial brain-training programs have risen in popularity, offering people the hope of improving their cognitive abilities through the routine performance of various “brain games” that tap cognitive functions such as memory, attention and cognitive flexibility. But a recent study at the University of

Research from Washington University School of Medicine in St. Louis, Radboud University Medical Centre in the Netherlands, and Stanford University shows that disrupting just one night of sleep in healthy, middle-aged adults causes an increase in a brain protein associated with Alzheimer’s disease. Further, a week of poor sleep leads to an increase in another

The findings of this study shed new light on how stress, depression and other mental states can alter organ function, and show that there is a real anatomical basis for psychosomatic illness.

The illustration on the right shows how the brain’s V1 and V2 areas might use information about edges and textures to represent objects like the teddy bear on the left.
