Exercising regularly in old age may better protect against brain shrinkage than engaging in mental or social activities, according to a new study. Research suggests that brain shrinkage may lead to problems with memory and thinking.
An inexpensive, five-minute eye scan can accurately assess the amount of brain damage in people with the debilitating autoimmune disorder multiple sclerosis (MS), and offer clues about how quickly the disease is progressing.
The hippocampus represents an important brain structure for learning. Scientists have discovered how it filters electrical neuronal signals through an input and output control, thus regulating learning and memory processes.
Multiple synaptic contacts between nerve cells facilitate the creation of a new contact, as neuroscientists report. An integral mechanism of memory foundation is the formation of additional contacts between neurons in the brain.
Frequently, as many as one thousand signals rain down on a single neuron simultaneously. To ensure that precise signals are delivered, the brain possesses a sophisticated inhibitory system. Scientists have now illuminated how this system works.
Temple Grandin, perhaps the world’s most famous person with autism, has exceptional nonverbal intelligence and spatial memory, and her brain has a host of structural and functional differences compared with the brains of controls.
Scientists have found compelling evidence that parts of the brain can evolve independently from each other. The brains of approximately 10,000 mice were analyzed. Seven individual parts of each brain were measured by volume and weight.
Boredom is often seen as a trivial and temporary, but it can also be a chronic and pervasive stressor that has significant consequences for health and well-being. Despite this, boredom itself is still poorly understood.
You already know it's hard to balance your checkbook while simultaneously reflecting on your past. Now, researchers -- having done the equivalent of wire-tapping a hard-to-reach region of the brain -- can tell us how this impasse arises.
