Less of a household name than colleagues such as Albert Einstein, Niels Bohr nevertheless contributed immensely to the developments of twentieth-century physics. Building on the work of his mentor Ernest Rutherford, Bohr developed his own atomic model that clarified and expanded the field of quantum theory.ess of a household name than colleagues such as Albert Einstein, Niels Bohr nevertheless contributed immensely to the developments of twentieth-century physics.

Norepinephrine and Depression. Norepinephrine and Depression. Norepinephrine functions both a neurotransmitter and hormone in the body. It is classified as a catecholamine hormone which is significant in the body's fight or flee response.hese depression symptoms caused by low level norepinephrine may be treated. There are medications available to counter the effects of low level norepinephrine in the body and treat the depression symptoms associated with it.
Studies showed imbalances in dopamine, norepinephrine, and serotonin in patients with depression. An SSRI and an SNRI both affect absorption of serotonin, but an SNRI also affects norepinephrine levels in the brain. Another difference between an SSRI and an SNRI is chronological. SSRIs were the first breakthrough drug for treating depression, and this type of medication is still widely used. SNRIs are more recent and may reflect more progressive research into the brain chemistry of depressed individuals.
