TL;DR: The results characterize developmental, neurochemical, neurobiological and electrophysiological consequences of brain-specific 5-HT deficiency, reveal a dual dose-dependent role of 5- HT in body weight regulation and show that differentiation of serotonergic neuron phenotype is independent from endogenous5-HT synthesis.

TL;DR: The results indicate that 5-HT mediates behavioral responses to environmental adversity by facilitating the encoding of stress effects leading to increased vulnerability for negative emotionality.

TL;DR: The results indicate that workers of B. terrestris possess elemental olfactory learning abilities, but, in contrast to previous findings in honeybees, fail in more complex tasks, such as negative pattern discrimination.

TL;DR: The current knowledge on immediate early genes (IEGs) in social insects is summarized, ideas for future research directions are provided, and a vast potential of using IEGs as neuronal activity markers to analyze the localization, function, and plasticity of neuronal circuits underlying complex social behaviors is revealed.

TL;DR: The data clearly show that bumblebees can learn to associate a color stimulus with a sugar reward in PER conditioning and that both workers and drones reach similar acquisition and mid-term retention performances and provide evidence that only workers transfer the learned information from a Pavlovian to an operant situation.
