Science Daily, Dec. 13, 2007UCLA researchers report that functional magnetic resonance imaging (fMRI) reveals clear differences in the areas of the brain involved in belief, disbelief and uncertainty.
Their results suggest that the differences among these cognitive states may one day be distinguished reliably, in real time, by techniques of neuroimaging. This finding has implications for the detection of deception, for the control of the placebo effect during drug design and for the study of any higher cognitive phenomenon in which the differences among belief, disbelief and uncertainty might be relevant.
Quality of Sleep Determines Where the Brain Stores Memories
PhysOrg.com, Dec. 13, 2007
A study investigating the role of sleep and memory shows how one night of sleep can lead to changes in brain activity six months after an event has occurred.
Researchers found that a good night's sleep after learning word pairs enhances memory processing in the hippocampus, and also induces information transfer between the hippocampus and medial prefrontal cortex (mPFC). This transfer serves to consolidate memories, helping new memories become stable and immune to interfering stimuli.
