[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.
Right hemisphere brain damage (RHD) is damage to the right side of the brain. The brain is made up of two sides or hemispheres. Each hemisphere is responsible for different body functions and skills.In most people, the left side of the brain contains the person's language functions.The right side contributes to a number of functions, such as attention, memory, reasoning, and problem solving (all of which contribute to effective communication). person with right hemisphere brain damage should see an SLP, a professional trained to work with people with communication disorders, in addition to his or her doctor. The SLP will work with the person and develop a treatment plan designed to improve his or her cognitive-communication abilities.
