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).
Surface waves move along the earth's surface. Photo is courtesy of Queensland University Advanced Centre for Earthquake Studies, Australia. The term earthquake refers to the ground vibrations that are induced by energy released into the earth during fault rupture. These vibrations are known as seismic waves.Seismometers operating around the globe on a continuous basis record the tiny displacements of the surface that are caused by seismic waves.uch slip occurs for a variety of reasons and typically differs from the steady inter-seismic slip described above (although in some sense, post-seismic slip is simply a subset of inter-seismic slip). A fault that has experienced a significant rupture often continues to accommodate significant slip after the rupture.
