After the workshop I co-presented with Les Posen, quite a few people were interested in the little nifty biofeedback system he presented. For those interested, the name of the system is EmWave and detailed information about it can be found on www.heartmath.com.
For those who did not attend the workshop: the system had very little to do with neuropsychology, but was very impressive, and useful for those who are doing treatment. It is mostly used for stress reduction and improvement in emotional self-regulation. A very nice gizmo for under $200. Good amount of information on the website.
