Neuroscience 1. “Thinking about Not-Thinking”: Neural Correlates of Conceptual Processing during Zen Meditation. Recent neuroimaging studies have identified a set of brain regions that are metabolically active during wakeful rest and consistently deactivate in a variety the performance of demanding tasks. This “default network” has been functionally linked to the stream of thoughts occurring automatically in the absence of goal-directed activity and which constitutes an aspect of mental behavior specifically addressed by many meditative practices. Zen meditation, in particular, is traditionally associated with a mental state of full awareness but reduced conceptual content, to be attained via a disciplined regulation of attention and bodily posture.
Using fMRI and a simplified meditative condition interspersed with a lexical decision task, we investigated the neural correlates of conceptual processing during meditation in regular Zen practitioners and matched control subjects.

The Secret World of Pain. For most of us, pain as a concept is something that we don’t spare a second thought: you stub your toe; it hurts for a bit, then it subsides. But for scientists, the experience of pain makes for fascinating study and an understanding of it can potentially unlock new methods of treatment and pain relief. Horizon reveals the latest research into pain and the breakthroughs that have been made, through studies on everyone from a woman in London who has felt no pain in her entire life, to a man in the US who cut off his own arm to survive, after it became lodged in a furnace.
Geneticist Dr. John Woods travels the world in search of people who feel pain in strange ways or don’t feel pain at all and believes that the secret of pain lies in our DNA. Meanwhile, we learn about the significance of early life experiences and their importance in developing our pain pathways. Watch the full documentary now -
