In London, an exhibition recently opened that features the work of what historic artist, whose name has stirred
debate because so many people pronounce it differently?

Van Gogh

Explanation:

The exhibition referenced in the question is "Meet Vincent van Gogh", interactive installation exhibition that opened in London in early February.

The audio guide that accompanies it started a debate because the artist's name is pronounced "Van Go", like it would be pronounced in America, rather than Britain version "Van Gof".

The Dutch version is more like "Van Khokh", but this event showed the name is differently pronounced in each country - Gof in Britan, Go in the US, Gog in France, etc.

there are treatment options for depression (mdd) that may work for you. one way of treating depression may be to affect the levels of certain chemicals that brain cells use to communicate, called neurotransmitters. scientists believe that certain neurotransmitters may be out of balance in depression.

although the exact way depression medications shown to ease overall depression symptoms in some people work is unknown, scientists think that some medications work by affecting the levels of a neurotransmitter called serotonin in the brain. other treatments work by affecting the levels of other neurotransmitters like norepinephrine or dopamine.
