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.
Declarative memory can be further sub-divided into episodic memory and semantic memory. Episodic memory represents our memory of experiences and specific events in time in a serial form, from which we can reconstruct the actual events that took place at any given point in our lives.
