“…Finally, in the rostrocaudal plane, disrupting glutamatergic neurotransmission via infusions of an AMPA/Kainate receptor antagonist generates appetitively motivated behaviors (e.g., ingestion) in the rostral medial AcbSh but aversively motivated behaviors (e.g., defensive treading) in the caudal medial AcbSh (Reynolds & Berridge, , ). Interestingly, these rostrocaudal variations in valence are dopamine‐dependent (Faure et al ., ), consistent with other findings implicating AcbSh glutamate and dopamine neurotransmission in aspects of aversive learning and motivation (Li & McNally, ,b).…”
