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.
A gradual transition from episodic to semantic memory can take place, in which episodic memory reduces its sensitivity and association to particular events, so that the information can be generalized as semantic memory. Both episodic memory and semantic memory require a similar encoding process.
