Document Summary
Retrieval practice: retrieve and use knowledge, such as answering quiz questions/ Question #1: fmri allows you to directly measure brain activity. (false) Question #2: fmri has high spatial resolution, but low temporal resolution. (true) Question #3: which method allows you to draw causal inferences about the relationship between brain and behaviour? (tms-transcranial magnetic stimulation) At 9 months, most neurons will have been born and migrated to target locations. At birth, most of the cortical neurons that will ever exist are in the correct location in the neurocortex. Newborn has many neurons but not many connections. But throughout the two years of life many connections are created (synaptogenesis) You have an initial process of connections but then you start to eliminate some of those connections. This happens in an upside-down u shape. Myelination: wrapping axons that ensures faster communication between synapses. Linear process, there is ongoing myelination into adulthood. Most of this data comes from animal research.
