Chapter one Study of physiological, evolutionary, and developmental mechanisms of behavior and experience o Emphasis on the study of areas and sub-areas of the brain o Brain area’s function depends on communication among neurons, the “building blocks of behavior” o Neuron activity somehow produces behavior and experience o “biological psychology is the most interesting topic in the world” Physiological- relates a behavior to the activity of the brain and other organs ( area of brain male songbird- grows larger through the influence of testosterone, enabling the male songbird sing and attract a female songbird) Ontogenetic- describes the development of the structure or behavior (why genes and environment are both necessary for bird to sing) (nature& nurture) Evolutionary- examines a structure or a behavior in terms of evolutionary history Functional-describes why a structure or behavior evolved as it did Dualism- mind and body area different kinds of substances, that exists independently but somehow interact Plasticity Experience and brain activities appear to be inseparable. Stimulation of any brain area provokes changes in behavior and experience Changes in experience evoke particular patterns of brain activity Experience shapes brain Genetics of behavior Mendel- inheritance occurs through genes Chromosomes are strands of genes, normally in pairs-consists of double strands of DNA in a helix Genes are units of heredity that maintain their structural identity across generations- within chromosomes A genotype is an expression of a gene pair; phenotype expression of a physical characteristic DNA When DNA exists as a double strand in a helix, it makes up a chromosome When DNA exists as a single strand, it serves as a template for the synthesis of RNA Heritability An estimate of how much of the variance in population characteristics is due to heredity
