The Origins and Organization of Vertebrate Pavlovian Conditioning [PDF]

open access: yesCold Spring Harbor Perspectives in Biology, 2015
Pavlovian conditioning is the process by which we learn relationships between stimuli and thus constitutes a basic building block for how the brain constructs representations of the world. We first review the major concepts of Pavlovian conditioning and point out many of the pervasive misunderstandings about just what conditioning is. This brings us to
