Week 2 Parts of Brain and Functions Flashcards
What is the main roles of left hemisphere
Logic, reasoning and language
Main role of the right hemisphere
Creativity
Name the four cortex lobes
Frontal, parietal, temporal and occipital
What is the frontal lobe responsible for
Higher cognitive functions like reasoning and social skills
What are mirror neurons
Fire when movements are seen and executed
What are the functions of the parietal lobe
Intergrates perceptual information
What are the functions of the temporal lobe
Memory and Sensory info
What are the functions of the occipital lobe
Visual info
What are the three parts of the brain stem
Pons, medulla oblangata and cerebellum
Function of the brain stem
Key role in life supporting movements (breathing, heart rate, blood pressure etc)
Function of cerebellum
Major role in rhythm production and error detection and correction
Function of limbic system
Learning, emotion and memory
Function of thalamus
relays sensory information into cortex
Function of hippocampus
required for learning
Strength of EEG and MEG
Strengths: non invasive and high temporal resolution
Strengths of Single Unit Measurement
Strengths: High temporal and spatial resolution
Strengths of PET and fMRI
Strengths: Non invasive and high spatial resolution
Weaknesses of EEG AND MEG
Weaknesses: Low spatial resolution and requires synchronised activity of large amount of neurons and only picks up some activity
Weaknesses of SIngle Unit measurement
Weaknesses: Usually only on animals who are killed afterwards
Weaknesses of PET and fMRI
Weaknesses: Low temporal resolution and expensive
