Researchers report on the important role the rostrolateral prefrontal cortex plays in keeping us on task.
The strength of a person's mental imagery is associated with excitability in the prefrontal cortex and visual cortex. Highly excitable neurons in the visual cortex may reduce a person's ability to imagine mental images. The findings shed light on how aphantasia, a condition where a person can not imaging mental images, may occur.
The spatial dissociation in Alzheimer's disease that causes people to wander may be a result of tau accumulation in the entorhinal cortex's grid cells, a new study reports.
Transcranial magnetic stimulation applied to the parietal lobe improves the function of brain areas important for memory which are disrupted by aging. The study reports TMS helps improve memory in older adults experiencing memory loss to the level of younger adults.
According to researchers, high frequency dTMS increased beta endorphin levels, producing heightened feelings of reward following food ingestion. Researchers report this form of non-invasive brain stimulation could help alter food cravings in obese people.
According to a new study, the brain activity of those who dream during NREM sleep is closer to the activity of awake people, compared to those who do not dream.
