The prefrontal cortex (PFC) is the anterior part of the frontal lobes of the brain, lying in front of the motor and premotor areas.This brain region has been implicated in planning complex cognitive behavior, personality expression, decision making, and moderating social behavior.o define the prefrontal cortex as the projection zone of the mediodorsal nucleus of the thalamus builds on the work of Rose and Woolsey who showed that this nucleus projects to anterior and ventral parts of the brain in nonprimates. Rose and Woolsey however termed this projection zone orbitofrontal..
Immediately above the Moho, the velocities of primary seismic waves (P-waves) are consistent with those through basalt (6.7â7.2 km/s), and below they are similar to those through peridotite or dunite (7.6â8.6 km/s).
Earthquakes usually happens along a fault plate, the border between plates: Global plate tectonic map (click to enlarge the map). Earthquakes often trigger landslides, tidal waves and tsunamis. Powerful aftershocks frequently occur, causing further damage and increasing psychological stress.ntensity scales, like the Modified Mercalli scale and the Rossi-Forel scale, measure the amount of shaking at a particular location. So the intensity of an earthquake will vary depending on where you are. Sometimes earthquakes are referred to by the maximum intensity they produce.
