|
Peter and Rosemary Grant
|
showed that natural selection has effect in short periods of time
|
|
|
genotype
|
inherited genetic structure
|
|
|
phenotype
|
outward appearence and repertory of behaviors
|
|
|
DNA/GENES
|
dna is organized into tiny units called genes. segements of dna make up chromosomes.
|
|
|
genome
|
full sequence of genes found on the chromosomes with the associated DNA
|
|
|
human behavior genetics
|
unites psych and genetics to explore causal link between inheritance and behavior
|
|
|
heritibality
|
0-1
1: genetic 0: environmental |
|
|
evolutionary psychology
|
extend evolution to explain how the mind functions
|
|
|
Rene Descartes
|
the human brain is an animal machine that can be understood scientifically
|
|
|
neuroscience
|
study the brain
|
|
|
Phinaes Gage
|
damaged frontal lobe
|
|
|
Broca
|
studied "tan" and found that the same area of the brain is involved in language (broca's area)
|
|
|
lesions
|
highly localized brain injuries
|
|
|
rTMS
|
uses magnetic stimulation to create temporary and reversible lesions
|
|
|
Walter Hess
|
electrical stimulation to probe structures deep in the brain. provoked many things in cats
|
|
|
EEG
|
electrodes provide a tracing of the brain activity
|
|
|
PET scans
|
radioactive substanes are taken up by brain cells, machines can read the radioactivity emitted by these cells, this makes a portrait of the brain
|
|
|
MRI
|
generates pulses in the brain that are tuned to different frequences. this casues atoms to lune up with magnetic fields, and then vibrate when the pulse is turned off
|
|
|
fMRI
|
detects magnetic changes in the flow of blood to cells in the brain
|
|
|
central nervous system
|
all neurons in brain and spinal cord. integrates and coordinates all bodily functions, processes incoming neural messages coming from the spinal cord and commands diff. parts of the body
|
|
|
spinal cord
|
coordinates left and right and is responsible for quick reflexes that don't require the brain
|
|
|
peripheral nervous system
|
all the neurons forming the nerve fibers that connect the CNS to the body
(composed of somatic and autonomic) |
|
|
somatic nervous system
|
regulates actions of skeletal muscles
|
|
|
autonomic nervous system
|
sustains basic life processes (respiration, digestion, arousal)
(divided into parasympathetic and sympathetic) |
|
|
sympathetic nervous system
|
governs responses to emergency situations
(fight or flight) |
|
|
parasympathetic nervous system
|
monitors the routine operation of the body's functions
|
|
|
brain stem
|
structures regulate the body
|

|
|
|
pons
|
provides input to other structures in the brain stem and to the cerebellum
|
|
|
reticular formation
|
nerve cells that keep the brain alert.
