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 limbic system is comprised of four main structures: the amygdala, the hippocampus, regions of the limbic cortex and the septal area. These structures form connections between the limbic system and the hypothalamus, thalamus and cerebral cortex. The hippocampus is important in memory and learning, while the limbic system itself is central in the control of emotional responses.
