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.
Transcranial magnetic stimulation (TMS) shows promise in diminishing the effects of early dementia and proves a safe and effective method for treating acute migraine and PPA.
It is well documented that professional boxing causes neurological impairment. A new study reveals routine sparring can cause short term impairments in brain-muscle communication and a decrease in memory performance.
Expert pianists have altered mechanisms by with tactile and proprioceptive sensations suppress activity in the primary motor cortex.
Imagination helps us act altruistically, a new study reports. When we see others in trouble, we imagine how we can help before acting. Researchers implicate the medial temporal lobe subsystem in guiding our prosocial behaviors.

From artificial intelligence to animals and people in comas, researchers evaluate different methods to test the presence of consciousness.
Applying repetitive transcranial magnetic stimulation (rTMS) to the prefrontal cortex helps improve performance in working memory tasks for both young and older subjects. The findings could provide a potential new treatment option for those suffering from Alzheimer's disease and other memory-related problems.
Neuroimaging study reveals veterans who suffered a mild traumatic brain injury (mTBI) have higher levels of fast, high-frequency gamma waves in the prefrontal and posterior parietal lobes, areas of the brain associated with consciousness, attention and problem-solving.
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.
