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.

When to make PowerPoint slides available to students?
by Dr Shock in Dr Shock MD PhD
Normally I am used to put the slides of my lectures online on BlackBoard before the actual lecture. In this way the hand outs can be used to understand the material better, at least that is what I hope for. Others never give their slides to students because they’re afraid the students will not attend [...]... Read more »

Healthy Online Gaming and Browser Gaming
by Dr Shock in Dr Shock MD PhD
Gaming among college-aged men may provide a healthy source of socialization, relaxation, and coping. In college aged men there was no significant correlation between BMI, academic performance, social functioning and frequency of online game play.
