Study Notes
Genetics and Behavior
- Psychological research explores genetics to understand biological influences on behavior.
- Genetic differences can determine individual outcomes in disease susceptibility and survival.
Chromosomes and DNA
- Human reproductive cells (eggs and sperm) contain 23 chromosomes, made up of DNA strands.
Evolutionary Psychology
- Evolutionary psychologists investigate changes in behavior and cognitive processes across time.
Polygenic Traits
- Most physical and behavioral traits are influenced by multiple genes, known as polygenic inheritance.
Nervous System Structure
- The nervous system has two main divisions: the central and peripheral nervous systems.
- The central nervous system is composed of the brain and spinal cord.
- The pons, located in the brainstem, acts as a connector between the brain and spinal cord.
Brain Imaging Techniques
- Computerized Tomography (CT) scans use multiple X-rays to visualize sections of the body or brain.
- Electroencephalography (EEG) involves placing electrodes on the scalp to record brainwave activity.
Endocrine System
- The endocrine system includes glands that secrete hormones, which are chemical substances that regulate various bodily functions.
Natural Selection
- The theory of evolution by natural selection posits that organisms adapted to their environments have higher survival and reproductive rates.
Genetic Terminology
- Genotype refers to the genetic makeup of an individual, encompassing all inherited genes.
- Phenotype represents the observable physical characteristics influenced by the genotype and environment.
