Sensory relay cemetery that also regulated sleep and mood. Regulates nt and hormone release and processes olfaction. Neuroimaging: structure: ct scan: uses x-rays to visualize structure of the brain, mri: uses electromagnetic frequencies to visualise the brain issues. Aim: mind wandering, are high mind wonders could be easily distracted or maybe mind wonders are disengaged and not interested in the task you give them. 2. disengaged in from task so lower responses for all rare tasks sustained attention: the result should be a lower p300 for all rare tasks thus reduced sustained attention. Result: lower activity in p300 in frontal and parietal cortex were correlated with high mind wandering. Significance: high mind wanders are simply disengaged in task. Can pick up 1% difference in density.
