How does the noradrenergic nucleus locus coeruleus act on target networks to regulate behavior? In this issue of Neuron, Zerbi et al. (2019) combine functional neuroimaging and pharmacogenetics in mice to tackle that question, uncovering a network action underlying stress. And providing insight for cognition?

The trade-off between reward and effort is at the heart of most behavioral theories, from ecology to economics. Compared to reward, however, effort remains poorly understood, both at the behavioral and neurophysiological levels. This is important because unwillingness to overcome effort to gain reward is a common feature of many neuropsychiatric and neurological disorders.

Introduction: While several theories have highlighted the importance of the noradrenergic system for behavioral flexibility, a number of recent studies have also shown a role for noradrenaline in motivation, particularly in effort processing. Here, we designed a novel sequential cost/benefit decision task to test the causal influence of noradrenaline on these two functions in rhesus monkeys.
Methods: We manipulated noradrenaline using clonidine, an alpha-2 noradrenergic receptor agonist, which reduces central noradrenaline levels and examined how this manipulation influenced performance on the task.

Odors constitute one of the most ancient ways of communication among animals. Whereas the key role of olfactory communication is well established in insects or rodents, its contribution to primate behavior remains very speculative. In a recent report, Klailova and Lee [1] studied the variations of intensity of the typical steroid musk odor produced by wild adult male gorilla silverbacks during encounters with opponents from other social units (lone males or other groups).

The noradrenergic nucleus locus ceruleus (LC) is associated classically with arousal and attention. Recent data suggest that it might also play a role in motivation. To study how LC neuronal responses are related to motivational intensity, we recorded 121 single neurons from two monkeys while reward size (one, two, or four drops) and the manner of obtaining reward (passive vs active) were both manipulated.

Among all factors modulating our motivation to perform a given action, the ability to represent its outcome is clearly the most determining. Representation of outcomes, rewards in particular, and how they guide behavior, have sparked much research. Both practically and theoretically, understanding the relationship between the representation of outcome value and the organization of goal directed behavior implies that these two processes can be assessed independently.
