Hello Walaa,
this is a good question!
This is what Dr Hamer said about it: [https://learninggnm.com/SBS/documents/brain.html#Thalamus_Top|https://learninggnm.com/SBS/documents/brain.html#Thalamus_Top]
I think this is referring rather to the hypothalamus that directs the autonomic nervous system and hormonal system, while the thalamus is rather relaying sensory input to the cerebral cortex and to consciousness.
This is what contemporary science finds about the thalamus: [https://en.wikipedia.org/wiki/Thalamus]

Hope that helps!
