Decorative Chrome Plating. Decorative chrome plating is sometimes called nickel-chrome plating because it always involves electroplating nickel onto the object before plating the chrome (it sometimes also involves electroplating copper onto the object before the nickel, too).
Certain cortical areas of the frontal lobe which are included in the limbic system on functional grounds and by virtue of their hypothalamic and amygdaloid connections must also be considered part of the prefrontal cortex if the latter is defined as the projection field of the mediodorsal thalamic nucleus (MD).
The frontal cortex is a part of the brain that maintains very close ties with the limbic system. Yet the frontal cortex remains relatively calm during REM sleep. The prefrontal cortex, which is part of the frontal cortex, is heavily involved in thought and judgment when we are awake.
