Thalamus
The Thalamus is the large mass of gray matter in the dorsal part of the diencephalon of the brain with several functions such as relaying of sensory signals, including motor signals, to the cerebral cortex, and the regulation of consciousness, sleep, and alertness. [1]
The connection between the Thalamus with the Fornix nerve fibers and Limbic system, are directly related to our emotional experience, and the way we experience our emotions to open our heart intelligence is the key to our higher sensory perception.
