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).
We have talked above seismic waves and how they vibrate the ground which can lead directly to the collapse of structures. There are other, secondary effects that are caused by earthquakes, most often a result of strong shaking. A simple example common in many earthquakes are landslides.
