Document Summary
What proportion of behaviour results from genes and what proportion results from learning through the environment. Behavioral genetics: the study of the genes involved in the development and regulation of the nervous system. P: dopamine receptors causing good feelings u: mutations causing hoarding. P: melatonin sleep hormones u: evolutionary survival strategy. Serotonin: neurotransmitter that regulates sleep, appetite, memory, learning, temperature, mood, sexual behaviour. Serotonin transporter gene: regulates serotonin in the synaptic cleft. Drugs: can alter neurotransmitter levels in the synaptic cleft by altering reuptake, reception, or secretion, ex. Melatonin: sleep hormone produced in the pineal gland at night, makes us sleepy. Narcolepsy: tendency to rapidly fall asleep at any time, affected by orexin, a neurotransmitter that induces wakefulness. Heritability: the proportions of differences in a specific population that is caused by genetics. Concordance: the amount of similarly in phenotype between individuals. Intelligence: measured by iq tests that find substantial heritability, can be affected by your socioeconomic status.
