question 124

Multiple Choice

• C) There is a decrease in cortical activity in the diencephalon-the hypothalamus and thalamus-which in turn leads to a stabilizing of endocrine activities.
• D) There is further development in the prefrontal cortex, which is involved in higher level thinking processes.
