Memory failure is a common occurrence yet scientists have not reached a consensus as to how it happens. However, according to a new study at Beth Israel Deaconess Medical Center, Transcranial magnetic stimulation (TMS) is able to minimize forgetfulness by disrupting targeted brain regions as they compete between memories.
A new study which will be published in an upcoming issue of Psychological Science, finds changes in brain activity after only five weeks of meditation training.
In an ongoing quest to map the brain, scientists have determined how the brain works to understand others. According to a new study, the brain generates empathy in one manner for those who differ physically and in another method for those who are similar. In a paper published online by Cerebral Cortex, researcher Dr Lisa Aziz-Zadeh, suggests empathy for someone to whom you can directly relate — (for example, because they are experiencing pain in a limb that you possess) — is mostly generated by the intuitive, sensory-motor parts of the brain. However, empathy for someone to whom you cannot directly relate relies more on the rationalizing part of the brain.
The brain holds on to false facts, even after they have been retracted according to a report in Scientific American.
Psychologists have found that thought patterns used to recall the past and imagine the future are strikingly similar. Using functional magnetic resonance imaging to show the brain at work, they have observed the same regions activated in a similar pattern whenever a person remembers an event from the past or imagines himself in a future situation. This challenges long-standing beliefs that thoughts about the future develop exclusively in the frontal lobe.
Many dementia patients being prescribed antipsychotic drugs could be better treated with simple painkillers, say researchers from Kings College, London, and Norway.
Brain damage can cause significant changes in behaviour, such as loss of cognitive skills, but also reveals much about how the nervous system deals with consciousness. New findings reported in the July 2011 issue of Cortex demonstrate how the unconscious brain continues to process information even when the conscious brain is incapacitated.
Years after a single traumatic brain injury (TBI), survivors still show changes in their brains. In a new study, researchers from the Perelman School of Medicine at the University of Pennsylvania suggest that Alzheimer’s disease-like neurodegeneration may be initiated or accelerated following a single traumatic brain injury, even in young adults.
