According to the work of Simon Levay (1991), gay men and women have similarities in their hypothalamic brain structure.
Explanation:
Hypothalamic brain structure refers to that part of the brain that is located at the bottom centre of the brain and is usually of the size of an average walnut.
This structure is a small yet major part in the human brain and is associated with the secretion of different hormones. According to the study made by Simon Levay, the structure of this part of the brain has been found to exhibit similarities in gay men and women.
