“…Over 50 years of comparative research with animals and humans has yielded general agreement regarding principal functions of these circuits in mediating approach and avoidance emotions and motivating approach and avoidance behaviors (see Beauchaine & Zisner, 2017). It should be noted, however, that subcortical neural systems are structurally interconnected and functionally interdependent (see Beauchaine & Constantino, 2017; Beyeler, 2016; Corr, 2013). For example, the nucleus accumbens (a ventral striatal structure) and the amygdala share interconnections via the paraventricular nucleus and the stria terminalis (e.g., Dong, Li, & Kirouac, 2017).…”

In the past quarter century, emotion dysregulation has emerged as an increasingly important construct for understanding diverse adjustment problems in childhood, adolescence, and adulthood. Emotion dysregulation is now recognized across disciplines and theoretical perspectives as a transdiagnostic feature of various mental health outcomes, and is represented in multiple elements of the Research Domain Criteria matrix (e.g.

“…However, evolution created a separate process for punishment, and while it may seem redundant, 5-HT has been known to play a critical role in punishment. It is found that approximately 90% of 5-HT is secreted by gut chromaffin cells in response to noxious food, thus inducing vomiting or diarrhea (Beyeler, 2016; Zheng et al, 2016). Some plants exploit this function of 5-HT by expediting passage of seed through the digestive system.…”

“…In addition, some animals such as scorpion and wasp stings also use 5-HT to induce pain (Gu et al, 2016). Aversion is separated from reward in the evolutionarily lower animals (Beyeler, 2016). The nematode, Caenorhabditis elegans , can also be infected by pathogenic bacteria, even though it feeds on bacteria.…”

A Model for Basic Emotions Using Observations of Behavior in Drosophila

et al. 2019

Emotion plays a crucial role, both in general human experience and in psychiatric illnesses. Despite the importance of emotion, the relative lack of objective methodologies to scientifically studying emotional phenomena limits our current understanding and thereby calls for the development of novel methodologies, such us the study of illustrative animal models. Analysis of Drosophila and other insects has unlocked new opportunities to elucidate the behavioral phenotypes of fundamentally emotional phenomena. Here we propose an integrative model of basic emotions based on observations of this animal model. The basic emotions are internal states that are modulated by neuromodulators, and these internal states are externally expressed as certain stereotypical behaviors, such as instinct, which is proposed as ancient mechanisms of survival. There are four kinds of basic emotions: happiness, sadness, fear, and anger, which are differentially associated with three core affects: reward (happiness), punishment (sadness), and stress (fear and anger). These core affects are analogous to the three primary colors (red, yellow, and blue) in that they are combined in various proportions to result in more complex “higher order” emotions, such as love and aesthetic emotion. We refer to our proposed model of emotions as called the “ Three Primary Color Model of Basic Emotions .”
