PSYB57H3 Lecture Notes - Lecture 3: Frontal Lobe, Trigeminal Nerve, Astereognosis
Document Summary
We talked about functional methods, which allow us to see what the brain is doing in action. We talked about eeg ! it allows us to look at electrical signals generated from the brain. It picks up the signals through special electrodes. Through averaging the signals, which we call event related potentials, it allows us to characterize features of the electrical signals that are generated during mental processing. One thing this eeg method tells us is when a mental process is occurring with very good precision ! it has millisecond resolution to tell you when there are neural changes triggered in the brain. If we want to know exactly what the individual part of the brain do, we want a method that has better resolution for where signals are coming from ! this is where fmri is useful. Thus we can infer how the brain is working when you"re thinking.
