“…Feather pecking (FP) in chickens is the act of a bird plucking the feathers of other birds, which can be gentle or severe [38]. FP can include aggressiveness, fearfulness, and anxiety, but it is also proposed to display compulsive traits [202].…”

“…In chicken, the 5-HT content is higher in the amygdala compared to the thalamus or the striatum [38]. The index of the turnover (5-HIAA/5-HT) is lower in chicken compared to mammals [34,38]. In Indo-Pacific Bluestreak cleaner wrasse, Labroides dimidiatus, the 5-HT content is quite low (approximately 20 pg/mg) and homogenous in the forebrain, the diencephalon, and the cerebellum of the fish [39].…”

Serotonin (5-hydroxytryptamine, 5-HT) is acknowledged as a major neuromodulator of nervous systems in both invertebrates and vertebrates. It has been proposed for several decades that it impacts animal cognition and behavior. In spite of a completely distinct organization of the 5-HT systems across the animal kingdom, several lines of evidence suggest that the influences of 5-HT on behavior and cognition are evolutionary conserved. In this review, we have selected some behaviors classically evoked when addressing the roles of 5-HT on nervous system functions.In particular, we focus on the motor activity, arousal, sleep and circadian rhythm, feeding, social interactions and aggressiveness, anxiety, mood, learning and memory, or impulsive/compulsive dimension and behavioral flexibility. The roles of 5-HT, illustrated in both invertebrates and vertebrates, show that it is more able to potentiate or mitigate the neuronal responses necessary for the fine-tuning of most behaviors, rather than to trigger or halt a specific behavior. 5-HT is, therefore, the prototypical neuromodulator fundamentally involved in the adaptation of all organisms across the animal kingdom.The organization of the 5-HT systems is completely different between species ranging from a limited number of cells in Aplysia or Drosophila (100 5-HT immunoreactive cells) to several thousand neurons in vertebrates. The variety and the heterogeneity of 5-HT neurons have been highlighted in vertebrates [7] as well as in invertebrates [8]. In general, the 5-HT systems in animals comprise 5-HT neurons, which share a particular shape made of thousands of varicosities, leading to the concept of volume transmission [9], and several 5-HT receptors (5-HTRs). In vertebrates, 5-HT neurons are localized in the midbrain raphe nuclei described as the B1-B9 cell groups [1,10]. The raphe pallidus, obscurus, and pontis form a caudal cluster (B1-B5), whereas the dorsal raphe and median raphe form a rostral cluster in the pons (B6-B9) [11]. The caudal raphe group projects to the spinal cord and the rostral group to the forebrain via an extensive and diffuse innervation. The dorsal raphe nucleus contains the highest number of 5-HT neurons and its anatomical sub-regions display some degrees of specific innervation of the forebrain [12][13][14]. The median and dorsal raphe nuclei receive excitatory and inhibitory inputs from most brain areas [15]. In crustaceans or insects, 5-HT neurons are widely present in each of the ventral cord ganglia, display large local ramifications that act in multiple neuropil areas, and some axonal branches form three pairs of rostrocaudal fibers [16][17][18][19]. Presumably, two of those fibers would project anteriorly and one posteriorly to the entire nervous system [20]. 5-HT neurons are often localized close to sensory integration input area in the brain of arthropods and some 5-HT cells in the abdominal ganglia of crayfish nerve cord are sensitive to the mechanical stimulation of abdominal segmental fringe hairs [21]. In cnidarians, 5-HT cells ...

“…Laying hens divergently selected on FP, resulting in high (HFP) and low FP (LFP) lines [22], differ in their responses to behavioral tests. HFP birds respond more actively compared to LFP birds [23][24][25][26] and compared to unselected control (CON) birds [26], suggesting that HFP birds have a more proactive coping style. These FP selection lines further differ in their stress response and serotonergic activity.…”

“…These FP selection lines further differ in their stress response and serotonergic activity. HFP birds had higher corticosterone (CORT) levels after manual restraint (MR) [27] and vocalized sooner and more, but struggled later and less compared to LFP birds during MR [25]. Furthermore, HFP birds had lower central serotonergic activity at young age, but higher central serotonergic activity compared to LFP birds at adult age [25].…”

 Physiological & behavioral measures were studied in relation to feather pecking (FP)  Stress response, natural antibody titers, corticosterone & 5-HT level were identified  FP genotypes differed in behavioral responses, 5-HT level & natural antibody titers  FP phenotypes differed in behavioral responses & 5-HT level  FP genotypes and FP phenotypes could not be categorized into coping styles
