Mechanism offers new insight into opening & closing the blood-brain barrier

Like a bouncer at an exclusive nightclub, the blood-brain barrier allows only select molecules to pass from the bloodstream into the fluid that bathes the brain. Vital nutrients get in; toxins and pathogens are blocked.

Researchers Show Human Learning Altered by Electrical Stimulation of Dopamine Neurons

Stimulation of a certain population of neurons within the brain can alter the learning process, according to a team of neuroscientists and neurosurgeons at the University of Pennsylvania. A report in the Journal of Neuroscience describes for the first time that human learning can be modified by stimulation of dopamine-containing neurons in a deep brain structure known as the substantia nigra.

Difference Found in Brain Area Linked to Memory Among College Football Players

Preliminary research finds that within a group of collegiate football players, those who experienced a concussion or had been playing for more years had smaller hippocampal volume (an area of the brain important for memory) than those with fewer years of football experience, according to a study in the May 14 issue of JAMA.
