The Marble Hand Illusion

Moshe Feldenkrais said “we move in accordance with our self image.” A new study provides some cool evidence that our self-image is easily modified, and that the modifications have physiological consequences. The illusion was created quite simply. Researchers repeatedly struck someone’s hand very gently with a tiny hammer. Each time the hand was struck, the natural… Read More

Watch Your Back: Mirrors Reduce Back Pain

I just read an interesting paper from Lorimer Moseley‘s group about how looking at your back in the mirror can reduce back pain. The paper describes a simple study where people with back pain were asked to make numerous repetitive provocative movements of the low back under two conditions: one group was able to see their… Read More

Review of Moseley/Hodges Talk Part Three

This is part three of my review of the Lorimer Moseley and Paul Hodges conference on pain and motor control. You can read parts one and two here and here. This section will describe Lorimer’s discussion of the body maps and their connection to pain, motor control and immune responses. The brain’s map of the… Read More

So I don’t have much time for blogging, but I do have time to link to three interesting recent articles which show… Read More

One of the main themes of this blog is that therapies attempting to treat chronic pain should target the brain for change, not just the body. Some recent studies based around sensory tricks or illusions provide further compelling evidence in support of this idea. 1. Big hand, small pain In the first study, researchers placed… Read More

The Rubber Hand Illusion

Neuroscience is to some extent an exercise in reverse engineering the brain. Reverse engineering means trying to understand how a complex device works without knowledge of its design or access to the owner’s manual. One of the basic tools of reverse engineering is to disable one part of the machine and then see what effect… Read More

The Thermal Grill Illusion

Body Map Error On this blog I frequently discuss the idea that pain can sometimes be caused by the brain’s faulty perception of the body as opposed to actual tissue damage to the body. Put another way, errors in the way the brain maps the body can cause threat which causes pain, even when there… Read More
