These phenomena express “conceptions” of things like the world according to Calvin Hall’s continuity theory. In the AIM (“A-I-M”) model, these phenomena are caused by interactions between aminergic and cholinergic neurons that generate PGO waves; that model of these phenomena is based on Hobson and McCarley’s activation-synthesis model. (10[5])Echidnas’ large (10[3])frontal cortex (-5[1])inspired (10[1])Crick (10[1])and Mitchison to theorize (-5[1])that these phenomena cause “reverse learning.” (10[3])Antti (10[1])Revonsuo theorized that these phenomena simulate probable threats. (10[8]-5[2])These (10[1])phenomena (10[3]-5[1])act (10[1])as (10[1])“wish fulfillment” (10[7]-5[1])according (10[3])to an (10[2])1899 (10[8])book (10[3])that described a (10[1])precursor (10[1])to the Oedipus (10[2])complex. (10[9])For 10 points, (10[2]-5[1])Sigmund (10[1])Freud (10[1])wrote (10[2])about the “interpretation” (10[6])of (10[3])what (10[2])phenomena (10[2])that occur during REM sleep? (10[2])■END■ (10[5])
