[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 frontal lobe governs our personality, character and behaviour. It is where we control our body movement and how we express ourselves. This part of the brain allows us to speak.It is also where we solve problems and do most of our learning.It allows us to organise and plan.he frontal lobe governs our personality, character and behaviour.
