Test 2 MODULE 5 Chromosomes Threadlike structures made of DNA molecules that contain the genes Genes the biochemical units of heredity that make up the chromosomal segments of DNA capable of synthesizing proteins DNA a complex molecule containing the genetic information that makes up the chromosomes Identical Twins develop from a single fertilized egg that splits in two 60 Fraternal twins develop from separate fertilized eggs Share a fetal environment but they are genetically no more similar than ordinary siblings 30 Genetic relatives biological parents and siblings Adoptees are more similar to their biological parents with personality traits Environmental relatives adoptive parents and siblings Epigenetics the study of environmental in uences on gene expression that occur without a DNA change Genes can be turned on or off by environmental factors ex Drugs or stress MODULE 6 Dual Processing Sleep and Dreams Consciousness our awareness of our environment and ourselves Allows us to assemble information from many sources as we re ect on our past and plan for the future Cognitive neuroscience the interdisciplinary study of the brain activity linked with our mental processes

without consciously experiencing it Recently blind woman acted liked se could see Parallel Processing enables your mind to take care of routine business Sequential Processing skilled at solving new problems which requires your focused attention Selective attention your awareness focuses like a ashlight beam on a minute aspect of all that you experience Cocktail party effect your ability to

relaxed but other body systems are active Kicks in about an hour after fall asleep Alpha waves the relatively slow brain waves of a relaxed awake state Hallucinations false sensory experiences such as seeing something in the absence of an external visual stimulus Delta waves the large slow brain waves associated with deep sleep Sleep cycle repeats about every 90 minutes Adults average 78 hours of sleep per night Melatoninsleep inducing hormone Why do we need sleep why sleep evolved a Sleep protects a Sleep helps us recuperate a sleep helps us restore and rebuild our fading memories of the day

neural functioning n Stimulants drugs that excite the neural activity and speed up bodily functions 0 Nicotine a stimulating and highly addictive drug in tobacco o Meth chemically related to its
