Behavioral functions of the mesolimbic dopaminergic system: an affective neuroethological perspective.

TL;DR: A comprehensive comparative analysis of the two neural circuits of social behavior network and mesolimbic reward system concludes that they were already present in early vertebrates and proposes that these circuits form a larger social decision‐making (SDM) network that regulates adaptive behavior.

TL;DR: The results demonstrate that reward has an impact on vision that is independent of its role in the strategic establishment of endogenous attention and suggests that reward plays an important and undervalued role in attentional control.

TL;DR: Since all vertebrates appear to have some capacity for primal affective feelings, the implications for animal-welfare and how the authors ethically treat other animals are vast.

TL;DR: The structure of opponency is considered in terms of previous biases about the nature of the decision problems that animals face, the conflicts that may arise between Pavlovian and instrumental responses, and an additional spectrum joining invigoration to inhibition to shed light on aspects of the role of serotonin and its interactions with dopamine.

TL;DR: Two classes of simple associative learning tasks that address the power of Pavlovian conditioned stimuli to gain access to representations of upcoming events and the construction of complex stimulus representations are discussed.

TL;DR: The present study is the first report on the simultaneous measurement of the post-synaptic release of a neurotransmitter and the electrophysiological recording of neurons identified to contain that transmitter substance.

TL;DR: The frequent occurrence and large magnitude of inherent phenotypic changes in cocaine responsiveness which are identified among inbred mouse strains now permits an analytical genetic study of processes underlying cocaine-mediated reinforcement.

TL;DR: The history of brain theory is described in terms of three kinds of theory of perception, which holds that perception works by the creation of information through chaotic dynamics by forming hypotheses about the environment, through which learning takes place.
