Neuropsychology Abstract of the Day: When Self-Report Is Invalid...
CONCLUSION: These results indicate that self-report of CMP in Mn-exposed residents appear to be invalid when compared to neuropsychological test scores. The participants ' misperception of having CMP is associated with less education and higher levels of depression. Neuropsychological assessment is recommended to attain valid results.

Do silicones really melt on your hair? Episode 131
Cosmetic Questions
Do silicones melt on your hair?
Kylie asks…I am attempting to remove years of black hair dye and came across Scott Cornwall and his product Decolour. He makes a claim that if it doesn’t work likely cause is hair plasticised due to using heat over 220 deg cel. Quote “If you use heated styling products such as hot irons you can seal this build up onto the hair, gluing down the cuticle layer, trapping in the silicone and making it difficult to remove. Is there scientific merit to this? Can silicone boil, coat the hair shaft and remain there plasticised for ever?
To answer this, I spoke with on...
