Dopaminergic neurons are found in the nucleusaccumbens (IB word). Why do we need a nucleusaccumbens? [1]
What is the ‘secondary messenger’ concept?[1]
Slow receptors can modulateFast receptors. How? [2]
Opioids bind to opioid receptors on widelydistributed pain pathways. Since they themselves are GPCRs they canact at a distance far from the opioid receptor.  Whateffect do opioids have on the pre- and post-synapticmembranes of neurons in the pain pathways? [4]
