Reduction of semantic memory could be an indicator of Alzheimer's disease 12 years before onset. Researchers examine different types of memory loss associated with dementia.
Within months of learning a new language, increased activity in brain areas associated with auditory processing, memory, and grammatical comprehension occurs. As language skills improve, the activity decreases.
Studying auditory regions and brain pathways in humans, apes, and monkeys, researchers have identified a language pathway that interconnects the auditory cortex with frontal lobe regions. The language pathway in other primates suggests an evolutionary basis in auditory cognition and vocal communication.
Listening to classical music during a lecture and again as you sleep can help improve test performance.
Multiple sclerosis patients who received N-acetylcysteine treatments had improvements in metabolism in brain areas associated with cognition and attention.
When people listen to music, the neural tracking of the frontal lobe lags behind the temporal lobe, but during music recall, the frontal lobe precedes that of the temporal lobe. The findings demonstrate bottom-up and top-down processes in the cerebral cortex during music listening and recall. The study provides important insights into how the human brain processes music.
Researchers argue humans did not evolve to be consistently happy but primarily survive and reproduce. Evolution, they say, placed an advantage on depression, preventing humans from engaging in risky or hopeless situations.
