emotional response magnitude and hypothalamus size

[valia]

What is the relationship between hypothalamus size and personal sensitiveness to emotions, that is sensitivity?
And the link hypothalamus size-endorphins production?
That is, the smaller the size of the hypothalamus, the fewer endorphins are released?
Thank you
