Biological Approach Flashcards
Methods to study the brain
Autopsies
examining the brains of corpses
Methods to study the brain
Selective Destruction
destroying specific parts of the brain to seeing the behavioural
Methods to study the brain - brain imaging
Functional
able to see the activity not the structure
Methods to study the brain - brain imaging
Structural
able to see the structure not the activity
Methods to study the brain
MRI - advantage
high resolution, little risk
Methods to study the brain
MRI - disadvantage
doesn’t indicate function
Methods to study the brain
fMRI - advantage
easy to carry out, little risk
Methods to study the brain
fMRI - disadvantage
unnatural setting, may not have ecological validity
Genetics and behaviour
Genotype
variants of a gene present in one’s DNA
Genetics and behaviour
Phenotype
individual characteristics (appearance or behaviour)
Genetics and behaviour
Monozygotic twins share….
100% of their genotype
Genetics and behaviour
Offspring share….
50% of their genotype
Neuroplasticity
Synaptic Plasticity
the ability of neurons to form new synaptic connections and break up old ones
Neuroplasticity
synaptic pruning
nerve cells making new connections with eachother
Neurotransmitters
Neurotransmission
the chemical communication between neurones
