Chapter 3 Flashcards
Expose the biological mechanisms that underlie behavior among many things
Biopsychology

Theory of evolution
Theory of evolution
Charles Darwin
The genetic difference between individual
Genetic variation
Long strand of genetic info, known as DNA
Chromosome
Helix shaped molecule made of nucleotide base pairs
dna
sequence of DNA, that controls or partially controls, physical characteristics known as traits
gene
consisting of two different alleles (Aa)
heterozygous
consisting of two identical alleles (AA/aa)
homozygous
Permanent change in a gene
mutations
asserts our genes to set the boundaries so we can operate
Range of reaction
our genes influence our environment, and our environment influences the expression of genes
Genetic environmental correlation
Study of gene environment interaction
epigenetic
membrane potential becomes less negative, making the neuron more likely to fire
Depolarization
membrane potential becomes more negative, making the neuron less likely to fire
Hyperpolarization
The level of charge in the membrane that causes a neuron to become active
threshold of excitation
an electrical signal
Action potential
Chemical messenger of the nervous system
Neuro transmitter
View the psychological disorders, like depression and schizophrenia are associated with imbalance in one or another Nero transmitter systems
Biological perspective
muscle action and memory
acetylcholine
Pain and pleasure
beta-endorphin
Mood, sleep, and learning
Dopamine
Heart, intestines, and alertness
