Therefore, the sense that is excluded as a function of the thalamus is smell. It is largely made up of gray matter and is located above the brain stem. They convey their instructions to the thalamus, which then relays this information back to the cortex This happens because the thalamus has rich connections to the limbic system, which controls our emotions – this enables the thalamus to have a flexible and contextual understanding of a situation; for example, heat is sometimes uncomfortable (scorching sun) and at other times may be pleasurable (e. These fibres give the nucleus a reticulated appearance, hence the name. For example, the portion of the thalamus that receives visual information will influence what visual stimuli are important, or what receives attention. The thalamus does not just pass the information on, it also processes that information. Its principal function is to relay motor and sensory information to the cerebral cortex. The sense of smell is handled directly by the olfactory system, which bypasses the thalamus. * * Sensory Aspects of the Thalamus Top.
