Answer:
Hypothalamus response to the signal of delta waves and secrets different hormones that regulate human body.
Step-by-step explanation:
The vital portion of human brain that contains nuclei of small size with different functioning is the 'Hypothalamus'. It secrets different hormones that helps in regulating body functioning. It is the connected link between the endocrine system and the nervous system.
It establishes coordination between hormonal behaviours, patterns of outputs of neuroendocrine system and circadian rhythms. This coordination requires response of the hypothalamus two different stimuli or signals. The signal of delta waving that arises at the thalamus helps in secreting hormones that regulate human body.
