Document Summary

Things that take longer (~10yr) for us to get good at will start to decline overtime first (in the last 10-15yr of our lives) Things that we develop from birth we will always be good at the last to deteriorate. Goal-driven (cognitive) attentional processes are the last to fully develop and the first to deteriorate. Stimulus-driven (perceptual) attentional processes are the first to fully deveop and. Development of cortical neurons picture in the chapters. Cortical attentional processing (more voluntary attention: more goal-driven mechanisms/attention symbolic cueing, reticular activating system (ras) primary controlling area for arousal. Damaged = possible comatose, overstimulated = hyper-active: superior colliculus midbrain/stem area that controls eye movements and attention shifts. Plots origin and destination points within its spatial maps. Progressive supranuclear palsy (psp) affects superior colliculus which affects motor functions and specifically eye movements. In early stage, vertical eye movement is difficult, but horizontal is not effected: due to this problem, psp patients do not show ior.
