*The '''extrapyramidal tracts''' pass through the medulla oblongata outside the ventral pyramidal tracts and have synapses within the brain stem nuclei. These synapses make it possible for signals travelling down the extrapyramidal horns to be influenced by other areas of the brain including the cerebrum.  The extrapyramidal tracts are generally responsible for activation of larger muscle groups and often work in a coordinated manner to achieve smooth synchronous movements.

===Limbic System===

===Limbic System===

The Limbic system is made up of parts of the brain bordering the '''corpus collosum'''. The Limbic system contains areas of '''cerebral cortex''', the '''cingulate gyrus''' (dorsally), the '''parahippocampus gyrus''' (ventrally), the '''amygdala''', parts of the '''[[Hypothalamus - Anatomy & Physiology|Hypothalamus Anatomy and Physiology]]''' (mamillary body) and the '''hippocampus'''. The limbic system is principally responsible for emotions and the various types of emotion can affect the activity of the ''[[Autonomic_Nervous_System_-_Anatomy_%26_Physiology|Autonomic Nervous System]]'', facilitated by the [[Hypothalamus - Anatomy & Physiology|Hypothalamus Anatomy and Physiology]].

===Olfactory Bulb===

===Olfactory Bulb===

The olfactory bulb is responsible for olfaction and the bulb itself is located within the rostral forebrain area, supported by the ''cribiform plate'' and the ''ethmoid bone''. The [[Equine Cranial Nerves - Horse Anatomy|olfactory nerves]] are connected directly to the limbic system. As a result, olfaction plays a central role and is particularly important in regulating/stimulating sexual behaviour.
