Limbic System-1

The brainstem (or brain stem) is the posterior part of the brain, continuous with the spinal cord. In the humanbrain the brainstem includes the midbrain, the pons and medulla oblongata of the hindbrain.
The brain stem sits above the spinal cord and has many connections between them. The brain stem, the most primitive part of the brain, is made up of the medulla, pons,cerebellum, midbrain, hypothalamusand thalamus. The cerebral cortex,limbic system and basal ganglia make up the forebrain.
The primary structures within the limbic system include the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia, and cingulate gyrus.
The amygdala is the emotion center of the brain,
 while the hippocampus plays an essential role in the formation of new memories about past experiences.
The limbic system is a set of structures in the brain that controls emotion, memories and arousal. It contains regions that detect fear,control bodily functions and perceive sensory information (among other things).
The limbic system is the portion of the brain that deals with three keyfunctions: emotions, memories and arousal (or stimulation). ...
The thalamus is located within the brainstem and is part of the pathway of information into the cerebrum, which is the section of the brain that is responsible for thinking and movement.
