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.
The other type of long term memory is procedural memory, which is the how-to section of the brain. The primary contrast between episodic and semantic memory is that episodic memories are memories which can be explicitly described and stated, while semantic memory is concerned with concepts and ideas.
