[Gravitational] waves are perturbations of spacetime which travel at c. However, spacetime is allowed to expand and contract faster than c. An expansion followed by a compression is pretty much the definition of a compression wave.
Damage to the brainâs frontal and temporal lobes causes forms of dementia called frontotemporal disorders. Frontotemporal disorders are the result of damage to neurons (nerve cells) in parts of the brain called the frontal and temporal lobes. As neurons die in the frontal and temporal regions, these lobes atrophy, or shrink.
The temporal lobe perceives and recognizes verbal material. It is among the most frequently injured parts of the brain during head injury. A person may have difficulty screening out distractions. Injury to the upper temporal area can cause someone to misunderstand what is said.
