Document Summary
Synesthesia = a cross-sensory experience, for example, when a visual image has a taste. Heredity involves passing along genes through reproduction. Genotypic variation is created by sexual reproduction. Social and environmental contexts influence genetic expression. The brain stem houses the basic programs of survival. Subcortical structures control emotion and basic drives. The cerebral cortex underlies complex mental activity. The peripheral nervous systems includes the somatic and autonomic systems. Actions of the nervous system and endocrine system are coordinated. The interplay of genes and environment wires the brain. Females" and males" brains are similar and different. Chromosomes = structures within the cell body that are made up of genes. Gene = the unit of heredity that determines a particular characteristic in an organism. Dominant gene = a gene that is expressed in the offspring whenever it is present. Recessive gene = a gene that is expressed only when it is matched with a similar gen from the other parent.
