Based on rat studies that show how maternal nurturing helps offspring respond better to stress propose a model to help explain why human children who are abused have a higher suicide rate

What will be an ideal response?


From rat studies, it could be proposed that human children that are abused will have decreased histone acetylation and increased DNA methylation associated with the genes for glucocorticoid receptors. These receptors in the hypothalamic region of the brain are important in mediating stress.
