Document Summary
Single: patient a has cognitive function x intact and y impaired. Double: patient a has cognitive function x intact and y impaired; patient b has x impaired, y intact. Thus showing the localization of different functions of the brain. Autonoetic consciousness thinking of self in past/future. Theory of mind putting ourselves in other people"s shoes (empathy) Single disassociation example article theory of mind is independent of episodic memory (autonoetic consciousness) Eeg: recording the brain"s electrical activity with electrode on scalp. Erp: recording electrical activity linked to occurrence of an event (e. g. presentation of a visual stimulus) This does not give us a lot of spatial info ( where the activity is occurring) compared to more hemodynamic methods. 1st study of hemodynamic brain processes: does thinking make your brain heavier? (angelo mosso) Low temporal resolution, but good spatial resolution. The advantage: using pharmacological tracers fmri functional magnetic resonance imaging.
