Document Summary
Mindful awareness: maintaining attention on anchor, sustained attention (not mind wandering, mindfulness based stress reduction can help improve immune function, accelerate healing, well-being, mindfulness involves sensing everything (feelings, judgements, thoughts) as they come and go. Involves: non-reactivity to inner experience: perceiving without needing to react, observing: staying alert to sensations, non-judgement of experiences: not deciding if thoughts are good/bad. Posterior cingulate cortex mind wandering region, older area: dorsolateral prefrontal cortex and executive control sustained attention area, meditators have more connections with cingulate cortex, activated at same time, deeper connections with limbic system. Lateral geniculate nucleus: cluster of cell bodies in thalamus, info goes from lgn to primary visual cortex. Lingual gyrus: areas v2 and vp (higher cortical regions more complex) 6 cortical layers, binding problem at most elegant level with visual processing. Sends info from lgn to extrastriate cortex (tissue outside striation) areas for higher order processing.
