Grooming is a commonplace, robust behavior in rodent species. It has been shown to be highly sensitive to a number of experimental factors, making it an ideal target for manipulation. The complex patterning of grooming in rodents, which usually proceeds in a cephalo-caudal direction and involves several distinct stages, can be dissected into its constituent parts and microstructures. Several grooming patterning analysis methods are described in the protocol that allow for an assessment of this behavior based on measurements of grooming activity and its sequencing. Additionally, grooming can be evaluated in reference to the regional distribution and syntax in which it occurs. Owing to the ever-increasing number of rodent models that have strong grooming phenotypes, this high-throughput in-depth analysis is becoming crucial for biomedical research.

In experimental pain studies involving animals, subjective pain reports are not feasible. Current methods for detecting pain-related behaviors rely on human observation, which is time-consuming and labor-intensive, particularly for lengthy video recordings. Automating the quantification of these behaviors poses substantial challenges.

Background: (absent, small, or homeotic-like 1), a histone methyltransferase, has been identified as a high-risk gene for autism spectrum disorder (ASD). We previously showed that postnatal severe deficiency in the prefrontal cortex (PFC) of male and female mice caused seizures. However, the synaptic mechanisms underlying autism-like social deficits and seizures need to be elucidated.

Orofacial pain is one of the most common causes of chronic pain leading to physical and cognitive disability. Several clinical and pre-clinical studies suggest that chronic pain results in cognitive impairment. However, there is a lack of meta-analyses examining the effects of orofacial pain models on behavioral learning and memory in rodents.

Growth differentiation factor 15, GDF15, and glucagon-like peptide-1 (GLP-1) analogues act through brainstem neurons that co-localise their receptors, GDNF-family receptor α-like (GFRAL) and GLP1R, to reduce food intake and body weight. However, their use as clinical treatments is partially hampered since both can also induce sickness-like behaviours, including aversion, that are mediated through a well-characterised pathway via the exterolateral parabrachial nucleus. Here, in mice, we describe a separate pathway downstream of GFRAL/GLP1R neurons that involves a distinct population of brain-derived neurotrophic factor (BDNF) cells in the medial nucleus of the tractus solitarius.

Research has shown child sexual abuse (CSA) within youth-serving organizations (YSOs) often went undetected for decades, which may in part be due to the use of sexual grooming behaviors. One such YSO is the Boy Scouts of America (BSA), with nearly 100,000 individuals alleging CSA within this organization. This study aimed to describe the characteristics of CSA within the BSA and the presence of sexual grooming behaviors as described by the Sexual Grooming Model.
