Sperry argued that consciousness is an emergent property= ‘’mind’ comes as a result of brain processes, but is not itself a component- meaning that the mind is not reducible to or predictable form other features of the brainOnce C does emerge, then it can have influence over lower-level functions = emergent causation Mutual interaction between neural and mental events Mind was seen as a supervenient= mental states may influence neuronal events while being influenced by them oEvent-related Potentials(ERPs)Earliest imaging technique= computed tomography (CT) Detailed anatomical data Magnetic resonance imagining (MRI)Greatest with spatial resolution Neither provide images for brain activity, only structuresBrain activation records provide sensory info pathways + response-related processes ERP= electrical signals recorded form the brain that occur after the onset of a stimulus Brain emits electrical signals, recorded by electrodesRepresented by wavelengths Present P with different items, and record ERPs from each item Problem: ERPs are good at recording activity, but not easy to determine the underlying cognitive processes oPositron Emission Tomography(PET)Imaging technique where P is injected with a radioactive substance that mingles with the blood and circulates to the brain. A scanner is then used to detect the flow of blood to particular areas of the brain Assumes that when a psych fnxn is engaged, then only those parts of the brain will be engaged/ needing more blood flowActive parts of the brain use up O2 at a faster rate Problem: limits to the amount of P’s radiation intakeoFunctional Magnetic Resonance Imagery(fMRI)= a non-radioactive magnetic procedure for detecting the flow of oxygenated blood to various parts of the braintaken over the method of PET place P in a large magnetic field/ causes atoms in brain to become aligned with the magnetic field changes of O2 in blood are thus picked up as alterations in the magnetic field = image of cortical activity Ex. fMRI on reading- reveals brain areas active in language processing wide indvl differences per P View of the brain is no longer phrenological nor just localizatn
