CHAPTER 1 Flashcards
Why bother with cog neuro?
so we can improve understanding of the brain, what treatment, policy or practice is neccesary for how/when to treat something
Techniques in Cog Neuro
fMRI, MRI, EEG, PET
Multiple levels of analysis
Molecular/cellular structure and composition, Single cell recordings, ERP/MEG recordings (electrical activity), PET/fMRI (metabolic activity/blood flow) => where in the brain?, Patient studies, Temporary lesions (TMS), Behavior
Definition of cog neuro
study of how the body enables the mind
2 central themes of cog neuro
Nature Vs Nurture and Localization Vs “holism”
Nature
Refers to rationalism, through right thinking and rejection of unstoppable or superstitious beliefs.
Nurture
Refers to empiricism, idea that all knowledge comes from sensory expereince
Localization
The belief that certain parts of the brain had certain jobs
“Holism”
The belief that the entire brain/ whole brain is involved with every cognitive function
Early views of cog neuro
ancient cultures “heart was the seat of emotions, brain is “cooling” organ, philosophers like rene descartes believed that nerves contained fluid or “spirits” and these spirits were responsible for the flow of sensory and motor information for the body. Ancient media scrolls
Phrenology (Gall)
Bumps in the skull indicate overdeveloped brain regions, bigger brain does not equal better
aggregate field theory
developed by Flourens, the belief that the whole brain participates in behavior
Cytoarchitectonics
the way in which cells differ between brain regions
Broadmans areas
analyzed the cellular organization of the cortex and characterized 52 distinct regions of the brain.
Neuron Doctrine
the concept that the nervous system is made up of individual cells, dicovered by Cajal
