If you take a single hair in between your fingers and you don't feel anything, then you have fine hair. If you can feel the hair, then it's medium. If you feel a strong, thick strand, then you are coarse. Don't confuse the density of hair with diameter, Papanikolas emphasizes.
Brain 101: Topics in Neuroscience. Semantic Memory. Semantic memory is strongly language-based and describes memory for facts and words. This can be thought of as a form of non-declarative memory because the knowledge is often not associated with a particular time or place. However, semantic memory must be thought of as separate because damage to brain regions that impair semantic memory do not always affect other forms of non-declarative memory, and visa-versa. Episodic Memory.
Our autobiographical memory contains memories of events that have occurred during the course of our lifetime. 1  It can be divided into episodic and semantic memories. Our episodic memories help us recollect times, locations and people while semantic memories deal with general facts. Our knowledge base consists of information pertaining to ourselves including what we are, what we were and what we may become.
