Major Issues Genetics Behavior Use Animals Research
Chapter 1: Sections 1, 2, 3,
Study of physiological, evolutionary, and developmental mechanisms of behavior and experience
What does a neuron do?
Receives information/transmits it to other cells by conducting chemical impulses
What do glia do?
Cell in nervous system does not conduct impulses across large distances
Relates behavior to the activity of the brain and other organs.
Ex: Chemical reactions that enable hormones to influence brain activity
How a structure or behavior develops
a structure or behavior evolved as it did
Ex: Genetic drift
Question of how the mind is related to the brain
The view that everything that exists is material or physical.
The view that only the mind really exists and that the physical world could not exist unless some mind wee aware of it.
The view that mental processes and brain processes are the same things, described in different terms
I alone exist, ot I alone am conscious
Concerns why/how any kind of brain activity is associated with consciousness
Belief the universe consists of only one substance
Units of heredity that maintain their structural identity from one generation to another.
Strands of genes
Identical pairs of genes on two chromosomes
Unmatched pair of genes is hetero
Gene either shows strong effect in homozygous or heterozygous condition
All other chromosomes are autosomal chromosomes and their genes are known as
Distinct from the sex-linked genes, sex-limited genes are present in both sexes, generally on autosomal chromosomes, but active mainly in one sex
"From one egg"
"From same egg"
Variation in some characteristic depend largely on genetic differences, then it has high heritability
Tendency for small genetic influences to change the environment in a way that magnifies change
Genetic inability to metabolize the amino acid phenylalanine
How genes change over generations
Individuals are chosen with desired traits so that they become parents of the next generation
If certain abilities are execised, those strong points will be passed along to offspring. There is not truth to this. It's bullshit. Thanks for including it in the textbook.
The number of copies of one's genes that endure in later generations
Deals with how behaviors have evolved, especially in social behaviors
1) Underlyin mechanisms of behavior are similar across species and sometimes easier to study in a nonhuman species.
2) We are interested in animals for their own sake
3) What we learn about animals sheds light on human evolution
4) Certain experiments cannot use humans because of legal/ethical restrictions
Tolerate animal research under certain conditions - some are okay and others are not
No room for compromise - It's never okay to use animals seeing as they have the same rights as humans
Brain activity and mental processes are the same but different. So the mind is acually brain activity.
Difference between states of consciousness and identifying structure/function relationships
WHY does brain activity produce consciousness? What is the purpose of consciousness?
All other genes except for sex-linked genes
Genes on sex chromosomes
within a species, individuals vary in physical/behavioral characteristics
Offspring inherit characteristics from their parents
Characteristics which enhance survival from their parents
* Evolution requires variation *
Reasons for Animal Research
- Underlying mechanisms of behavior are similar across species
- For their own sake
- Sheds light on evolution
- Unethical to use people
