More Than Just Being A Sentimental Fool: The Psychology Of Nostalgia:

The research, published in Nature Genetics, identified the hormone Neurokinin B as a critical part of the control system that switches on the master regulator of human puberty. Although Neurokinin B was previously known to be present in the hypothalamus, the part of the brain that controls puberty, its key role was not previously appreciated.

Research conducted by a team in Switzerland suggests that a family of genes involved in regulating the expression of other genes in the brain is responsible for helping us deal with external inputs such as stress. Their results, appearing in the journal Neuron, may also give a clue to why some people are more susceptible to anxiety or depression than others.
