Diencephalic projection to reticulospinal neurons involved in the initiation of locomotion in adult lampreys Lampetra fluviatilis.
http://www.ncbi.nlm.nih.gov/pubmed/9421142    
    "
The projections from the Ventral Thalamus  to the reticulospinal neurons in the PRRN and MRRN thus provide excitatory inputs to the reticulospinal neurons, which, in turn, can activate the spinal circuits underlying locomotion."

Diencephalic and mesencephalic projections to rhombencephalic reticular nuclei in lampreys.
http://www.ncbi.nlm.nih.gov/pubmed/9748487   
    This makes it sound as though behavior is initiated in the rhombencephalon, which is way below the NAC, GP, STN, Th, PTc and Tec

Descending GABAergic projections to the mesencephalic locomotor region in the lamprey Petromyzon marinus.

My comments:   
    This paper provides strong support to my impression that release of GABAergic inhibition is an important, and perhaps even necessary, part of behavior.
