Behavioral functions of the mesolimbic dopaminergic system: an affective neuroethological perspective.
TL;DR: The affective neuroethological perspective presented here views the ML-DA system in terms of its ability to activate an instinctual emotional appetitive state (SEEKING) evolved to induce organisms to search for all varieties of life-supporting stimuli and to avoid harms.

The Vertebrate mesolimbic reward system and social behavior network: A comparative synthesis
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.

Reward Changes Salience in Human Vision via the Anterior Cingulate
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.

The basic emotional circuits of mammalian brains: do animals have affective lives?
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.

Opponency Revisited: Competition and Cooperation Between Dopamine and Serotonin
Y-Lan Boureau,Peter Dayan +1 more
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.

Ethological analyses of crayfish behavior: a new invertebrate system for measuring the rewarding properties of psychostimulants
Jules B. Panksepp,Robert Huber +1 more
TL;DR: Behavioral studies in crayfish can provide a complementary approach to using other invertebrate species in addiction research, and demonstrated that (mammalian) drugs of abuse, capable of interfering with monoamine chemistry, are similarly rewarding tocrayfish.

Dopamine enhances spatiotemporal spread of activity in rat prefrontal cortex.
TL;DR: Dopaminergic modulation of prefrontal cortex (PFC) is important for neuronal integration in this brain region known to be involved in cognition and working memory and lowers the threshold for epileptiform activity in local excitatory circuits within PFC.

Ndn, volume transmission, and self-organization in brain dynamics
TL;DR: The hypothesis is developed that the synchronization manifests continuous distributions of activity in cortical neuropil that modulate firings of selected neural networks embedded in the Neuropil, which instantiate volume transmission by nonsynaptic diffusion transmission, in concert with the self-organization of the textured neural activity that supports cognition.
Single unit activity of dopaminergic neurons in freely moving cats
TL;DR: This study represents the first systematic report providing evidence for recording the activity of dopaminergic neurons in freely moving cats, and when these cells were studied across the sleep-waking cycle they displayed little variation in firing rates between waking, slow wave sleep and REM sleep.
