The Biochemistry of Falling in Love

You broke my....hypothalamus

 The available data indicate that romantic love feelings commence
in the region of the lower brain that is known as the hypothalamus. The
hypothalamus is composed of a dense cluster of nerves which controls
hundreds of bodily functions and impacts in a large host of ways the
entire nervous system. Whenever a person subjectively perceives another
human being as romantically appealing a portion of the hypothalamus
transmits a message by way of various chemicals to the pituitary gland.
And in turn the pituatary releases a host of its own hormones which
rapidly suffuse the entire bloodstream. The sex glands respond to these
hormones by rapidly releasing into the bloodstream their own hormones
which have the effect, even among preadolescent children, of creating a more
rapid heartbeat and a feeling of lightness in the head. Simultaneously
the nerve pathways in and around the hypothalamus produce chemicals
that induce-provided that these chemicals continued to be produced over
a long period of time-what people refer to as "falling in love".
