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.
There are arguments among researchers regarding the location of semantic memory. Certain sections of researchers believe that it is stored in the same regions as episodic memory, mainly the hippocampus and medial temporal lobe. Memories are encoded in the hippocampus before they are stored in the medial temporal lobe. Yet recent research suggests that semantic memory encoding has
