This is the personal blog of a Dutch psychiatrist working in a University hospital. His specialty in psychiatry is the treatment of depression. This explains his interest in electroconvulsive therapy and the development of new forms of neurostimulation for the treatment of depression. He is also involved in medical education. He does research in the treatment and neuroscience of depression. He mostly writes about these topics on this blog for fun and to keep up with recent developments. Besides writing about his work he also writes about other subjects that (neuro)stimulates him such as chocolate, computer gaming, gadgets, and Internet. The postings are based on what I want to write about and what I feel will be interesting to read.
