PSYC 7 Lecture Notes - Lecture 4: Visual Cortex, Synaptogenesis, Visual Acuity
Document Summary
Growth of a specialized brain: brain-mapping methods. Methods to study origins and time course of brain specialization. Measuring the brain"s electrical activity through electrodes place on scalp (eeg) Not as great picture of where in the brain is happening. Using magnetic fields to track brain blood flow (functional magnetic resonance imaging) (fmri,meg) Not as specific in when the neurons are firing but very clear picture of the brain: five general principles of brain specialization. Brain is specialized to produce specific behaviors immediately from birth and even before. Dehaene-lambertz: left hemisphere specialized for language processing very early (2-3 months old at latest) Active regions become more precise, stimuli that trigger activity become more precise. Activity in the brain are known to process certain stimuli (view face, a part of brain is very active) Stimuli that trigger activity become more precise over time. Understanding faces which have correct face features and not just a jumbled mess.
