If you've ever had a song stuck in your head, you'll be interested in the latest research investigating the brain region responsible for recognition of familiar tunes revealed as part of a study into Semantic dementia.
Semantic dementia research
Semantic dementia (SD) is a rare type of dementia characterised by a loss of semantic memory, memory for generalised concept based factual information (i.e, general knowledge). The most common symptoms, particularly early on, are an impaired ability to retrieve words from memory and impaired comprehension of word meanings. It also affects patients' ability to recognise objects and sounds.
