Attentioninvolves interaction of sensory cues andthe corresponding actions. Attentionprocessing and action occurs throughout the brain in the prefrontal cortex both in areflexive/reactive manner and a thoughtful intentional manner.-Reflexive attention (“bottom up”; RAS control): startleresponse, action beforethinking.-Executive processing (“top down”; frontal lobe): reactiveresponse, prefrontal cortexis rationalizing the stress, controlled by memory, thinking before action*The fundamental role of the RAS is regulating arousal/sleep/wakecycles AND ourattention AND sympathetic nervous system/startle response.
Types of Attention:-Focused: Noticing and responding toone specific stimulus-Sustained: sustaining concentration withvigilanceover time-Selective: Noticing and responding to a stimuluswhilefiltering distractions-Alternating: Movingbetween taskshavingdifferentcognitive requirements-Divided: respondingsimultaneouslyto multiple tasksor demands4.When examining the regulation of behavior howdoes the prefrontalcortex help to influence that behavior.
5.How do neurotransmitters regulate mood, attention,and behavior?(GABA) and Acetylcholine. Which neurotransmitters are excitatory andwhich neurotransmitters are inhibitory, what does this mean?
Schizophrenia↑ Dopamine in cortical brain areas↓ Dopamine in limbic brain areas↓ Dopamine6.What is traumatic brain injury (TBI), how arethe prefrontal cortex, theamygdala, and the neurotransmitters affected by TBI and what‘manifestations’ of TBI ‘would we ‘look to assess’ in response to TBI ‘fromthe prefrontal cortex, the amygdala and the neurotransmitters?
