Grooming in small felids has received little attention compared with grooming in rodents, bovids and primates where grooming is also common. This study set out to describe the general pattern, time budget and degree of cephalocaudal sequencing of self-oral grooming in the domestic cat. In 11 cats confined for the purposes of videotaping, sleeping and resting accounted for 50% of the time budget...

Grooming is one of the most conspicuous social interactions among nonhuman primates. The selection of grooming partners can provide important clues about factors relevant for the distribution of grooming within a social group. We analyzed grooming behavior among 17 semi-free ranging female Barbary macaques (Macaca sylvanus). We tested whether grooming is related to kinship, rank and friendship....

Serotonin transporter (SERT) and brain-derived neurotrophic factor (BDNF) are key modulators of molecular signaling, cognition and behavior. Although SERT and BDNF mutant mouse phenotypes have been extensively characterized, little is known about their self-grooming behavior. Grooming represents an important behavioral domain sensitive to environmental stimuli and is increasingly used as a mode...

Lactating rats exhibit stable individual differences in pup licking/grooming. We used in vivo voltammetry to monitor changes in extracellular dopamine (DA) in the nucleus accumbens (n. Acc) shell of lactating rats interacting with pups and found that (1) the DA signal increased significantly with pup licking/grooming; (2) the onset of such increases preceded pup licking/grooming; and (3) the ma...

Social networking sites (SNS) provide innovative social bonding methods known as social grooming. These have drastically decreased time and distance constraints of social grooming. Here we show two type social grooming (elaborate social grooming and lightweight social grooming) discovered in a model constructed by thirty communication data-sets including face to face, SNS, mobile phones, and Ch...

Vitamin D is a steroid hormone with several important functions in the nervous system. Numerous human and animal data link alterations in the vitamin D system to various behavioral disorders. Grooming is an important element of rodent behavior with a general pattern of cephalocaudal progression (paw licking - nose/face wash - body wash - tail/genitals wash). Here we studied whether genetic abla...

Grooming relationships between adult male chimpanzees are often reciprocal, i.e. individuals receive grooming from those they groom. Grooming may be reciprocated at the same time it is received (mutual grooming), or later within the same grooming session. Alternatively, it can be reciprocated at a much later stage, in another session. An analysis of individual grooming sessions at the dyadic le...

The parcelling model of reciprocity predicts that grooming partners will alternate between giving and receiving grooming within grooming bouts, and that each partner will perform approximately as much grooming as it receives within each bout (‘time matching’). Models of allogrooming based on biological markets theory predict that individuals of lower dominance rank will exchange grooming for to...
