Until the last few decades, the frontal lobes of the brain were shrouded in mystery and erroneously thought of as nonessential for normal function—hence the frequent use of lobotomies in the early 20th century to treat psychiatric disorders. Now a review publishing August 28 in the Cell Press journal Neuron highlights groundbreaking studies of patients with brain damage that reveal how distinct areas of the frontal lobes are critical for a person’s ability to learn, multitask, control their emotions, socialize, and make real-life decisions. The findings have helped experts rehabilitate patients experiencing damage to this region of the brain.

Scientists from the Florida campus of The Scripps Research Institute (TSRI) have identified a protein complex that plays a critical but previously unknown role in learning and memory formation. The study, which showed a novel role for a protein known as RGS7, was published April 22, 2014 in the journal eLife, a publisher supported by the Howard Hughes Medical Institute, the Max Planck Society and the Wellcome Trust.

A daily dose of the antioxidant fisetin keeps mice—even those with genetic mutations linked to Alzheimer's—from experiencing memory and learning deficits as they age.

In adults, some brain regions retain a “childlike” ability to establish new connections, potentially contributing to our ability to learn new skills and form new memories as we age, according to new research from Washington University School of Medicine in St. Louis and the Allen Institute for Brain Science in Seattle.

To learn new motor skills, the brain must be plastic: able to rapidly change the strengths of connections between neurons, forming new patterns that accomplish a particular task. However, if the brain were too plastic, previously learned skills would be lost too easily.

In addition to being used as a recreational drug, marijuana has been used for centuries to treat a variety of conditions, from chronic pain to epilepsy. However, its medical value is greatly limited by debilitating side effects. A study published by Cell Press November 21st in the journal Cell has revealed the molecular pathways responsible for marijuana-induced learning and memory problems. The findings suggest that preventing these side effects could be as easy as taking an over-the-counter painkiller.
