Update
The core symptoms of ADHD are linked to what area of the brain? - ANSWERS
prefrontal cortex
Selective attention is due to what area of the PFC malfunctioning? - ANSWERS
dorsal ACC (anterior cingulate cortex)
sustained attention and problem solving linked to what area of the brain? -
ANSWERS DLPFC
hyperactivity is linked to what area of the brain? - ANSWERS prefrontal motor
cortex
what test assessing sustained attention? - ANSWERS N-back test
where is sustained attention modulated in brain? - ANSWERS CSTC loop in the
DLPFC
insufficient activation in the DLPFC can cause inattention
"sustaiNed attention- N back"
,what test assesses selective attention? - ANSWERS Stroop test
"Selective, Stroop, Cingulate"
where in the brain is selective attention modulated? - ANSWERS the CSTC
loop, Dorsal anterior cingulate cortex
issues with sustained attention are: - ANSWERS difficulty completing tasks

, interrupting
what part of the brain modulates hyperactivity? - ANSWERS prefrontal cortex
what are some key observations in the prefrontal cortex as it relates to ADHD? -
ANSWERS orbitofrontal cortex (OFC)-- impulsivity and hyperactivity
DLPFC/DaCC-- sustained/selective attention issues
how do NE and DA amounts manifest in relation to fatigue/anxiety? -
ANSWERS too little NE and DA = fatigue
too much = anxiety
what two receptors in the PRC are thought to be involved with ADHD treatment? -
ANSWERS alpha 2 a
D1
how does ADHD affect NE and DA levels? - ANSWERS NE levels low, signal
reduced
DA levels low, noise increased
results in: fidget and inattention
