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).
Activity Summary: Mauna Loa is not erupting. The seismicity rate is elevated above background, though at a lower weekly rate than reported in mid-to late-summer. Earthquakes occurred beneath Mauna Loa s upper Southwest Rift Zone and upper west flank at depths less than 13 km (8 miles).Deformation data are still consistent with inflation of magma reservoirs beneath Mauna Loa s summit and upper Southwest Rift Zone.ctivity Summary: Mauna Loa is not erupting.
