Document Summary

Frhd 2060 chapter 2: neuroscience as a basis for adult development and aging. Two techniques are used most often: structural neuroimaging: provides highly detailed images of anatomical features of the brain e. g. x-rays, ct, mri. Used for diagnostic purposes: functional neuroimaging: provides an indication of brain activity but not in high anatomical detail e. g. spect, pet, fmri, nirsi. Used to see which part of the brain is used under different conditions and scenarios. Very descriptive, uses lots of colour, different orientation. Activation imaging approach: attempts to directly link functional brain activity with cognitive behavioural data. Compensatory changes: changes that allow older adults to adapt to the inevitable behavioural decline resulting from changes in specific areas of the brain. At the most basic level, the brain is made up of neurons: key features of the neuron: Axon: contains neurofibers: structures that carry information inside the neuron from dendrites to terminal branches.
