A neuroethological approach to decision-making considers the effect of evolutionary pressures on neural circuits mediating choice.
We argue that caudate microstimulation can differentially increase stimulus values independent of action, and unilateral manipulations of value are sufficient to mediate choice behavior.
Although we would suggest that our data highlight attentional selection as secondary to central value-based decision processes in mediating choice behaviour, more work is needed to identify which aspects of the cue and the reward determine choice.
In both stages life-style motives were mediating that relationship, but, in addition, in the first stage, personal involvement, and in second stage, profession related, motives mediated the choice.
Dissecting the evolution of chemically mediated mate choice is often extremely difficult, as pheromone systems are frequently highly complicated, with multiple genes contributing to a complex blend of products constituting the species-specific chemical signal.
The aim of the current experiment was to employ a choice method to examine whether attentional selection between alcoholic and non-alcoholic drinks mediates the choice between those two rewards, following alcohol taste devaluation.
Such buffering would seem to be a prerequisite for MHC odortypes to be involved in mediating mate choice in natural environments, as studies in semi-natural testing conditions suggest [16].
Identification of potential targets of these neurons within distinct neuropil regions should provide valuable clues towards understanding how FruM/OA neurons function within neuronal frameworks to mediate the choice between courtship and aggression in adult male flies.
For identifying these neurons, it is significant that they may be distinct from those mediating innate choice behavior (Apostolopoulou et al., 2014; König et al., 2014).
In particular, the dorsal prefrontal cortex does not appear to be involved in mediating impulsive choice, yet does have some role in regulating inhibitory processes.
