Description
Adult locomotory behavior (GO:0008344) is a biological process defined as locomotory behavior in a fully developed and mature organism. This term captures the movement patterns, exploratory activity, and foraging behaviors that occur after an animal has reached adulthood, distinguishing them from larval or developmental locomotion. Researchers study this process to understand how neural circuits, genes, and environmental factors converge to produce coordinated movement in mature animals [1,5]. The importance of adult locomotory behavior extends across model organisms, from zebrafish and medflies to rodents and nematodes, where it serves as a readout for neurodevelopment, sensory processing, and motor function [1,2,4,5]. In Drosophila melanogaster, mutations in the foraging gene alter adult locomotory behavior specifically after feeding, demonstrating a genetic link between nutrient sensing and movement. Similarly, in C. elegans, environmental programming during development can reshape adult foraging behavior, highlighting the plasticity of this process. Because adult locomotory behavior integrates sensory input, neural integration, and motor output, it is a sensitive indicator of overall nervous system health and function [4,6].

What Is GO:0008344?
According to the Gene Ontology, adult locomotory behavior (GO:0008344) refers to locomotory behavior in a fully developed and mature organism. This definition emphasizes the adult stage, excluding larval or juvenile locomotion, and encompasses all forms of self-propelled movement used for exploration, foraging, escape, and social interaction in mature animals [3,5].
Why Is adult locomotory behavior Important in Cell Biology?
Adult locomotory behavior is a fundamental readout of nervous system function and is conserved across animal phyla. It integrates sensory perception, neural circuit activity, and motor execution, making it sensitive to genetic mutations, environmental toxins, and pharmacological agents [1,4,6]. Studies in Drosophila, C. elegans, zebrafish, and rodents have revealed that adult locomotory behavior is modulated by genes involved in nutrient sensing, oxidative stress, and neural signaling [3,4,5]. Because impairments in locomotion often accompany neurodegenerative diseases, anxiety disorders, and aging, this GO term provides a bridge between basic neurobiology and translational research [4,7].

What Happens During adult locomotory behavior?
Initiation and Sensory Integration
In simple terms: The animal senses its environment and decides to move.
Adult locomotory behavior begins with sensory input from visual, olfactory, and mechanosensory systems. In zebrafish, acute ethanol exposure alters locomotor activity and exploratory behavior, indicating that sensory processing and motivation are rapidly affected by pharmacological agents. In C. elegans, environmental cues during development program adult foraging behavior, showing that sensory experience can have long-lasting effects on locomotion.
Neural Circuit Activation
In simple terms: Brain circuits send signals to muscles to produce movement.
Once initiated, locomotory behavior requires the activation of central pattern generators and descending neural pathways. In Drosophila, mutations in the foraging gene affect adult locomotory behavior after feeding, suggesting that neural circuits controlling locomotion are modulated by nutritional state. In rodents, oxidative stress in the hippocampus is associated with decreased locomotory and exploratory activity, linking neural health to motor output.
Motor Execution and Coordination
In simple terms: Muscles contract in a coordinated way to move the body.
Motor execution involves the coordinated contraction of skeletal muscles, governed by motor neurons and proprioceptive feedback. In medflies, electronic recording of lifetime locomotory activity patterns reveals distinct daily rhythms and age-related changes in movement. In earwigs, exposure to reduced-risk insecticides alters locomotory behavior, demonstrating that motor coordination is sensitive to neurotoxic compounds.
Modulation by Internal State
In simple terms: Hunger, stress, and age change how much and how fast an animal moves.
Adult locomotory behavior is modulated by internal physiological states. In Drosophila, the foraging gene influences locomotion specifically after feeding, indicating that satiety signals alter motor activity. In rats, subacute vitamin A supplementation at therapeutic doses increases oxidative stress in the hippocampus and decreases locomotory and exploratory activity, showing that nutritional status can impact movement. In mice, oral supplementation of Ocimum basilicum improves locomotory and exploratory behavior, further highlighting the role of diet.
Age-Related Changes
In simple terms: Older animals often move less and differently.
Adult locomotory behavior changes with age. In medflies, lifetime activity patterns show declines in movement with advancing age. In humans, old-age emotions and behavioral changes have been discussed in geriatric literature, though direct molecular links to locomotion are less defined. These observations underscore the importance of considering age as a variable in studies of adult locomotory behavior.

How Is adult locomotory behavior Regulated?
Adult locomotory behavior is regulated by a combination of genetic, neural, and environmental factors. In Drosophila, the foraging gene acts as a molecular switch that modulates locomotion in response to feeding state. In C. elegans, environmental conditions during development program adult foraging behavior through TGF-beta and biogenic amine signaling pathways. Oxidative stress in the hippocampus can suppress locomotory and exploratory activity in rats, indicating that redox balance regulates motor behavior. Additionally, circadian clock genes control daily rhythms in locomotory activity, as shown in medflies. Pharmacological agents such as ethanol and insecticides can acutely alter locomotion by affecting neurotransmitter systems [1,8].
adult locomotory behavior and Human Disease
| Gene | Disease / Biology | Potential Experimental Model |
|---|---|---|
| for (foraging) | Nutrition-related motor deficits | Drosophila knockout |
| BDNF | Neurodegeneration, anxiety | Mouse knockout |
| COX-2 | Neuroinflammation | Rat overexpression |
| AChE | Neurotoxicity | Insect exposure models |
| DAT | Dopamine-related motor disorders | Mouse point mutation |
Neurodegenerative and Age-Related Conditions
Declines in adult locomotory behavior are observed in aging and neurodegenerative contexts. In medflies, lifetime activity patterns show age-related reductions in movement. In humans, old-age emotional changes have been discussed, though direct links to locomotion require further study. Rodent models of oxidative stress exhibit decreased locomotory activity, mimicking aspects of neurodegeneration.
Anxiety and Mood Disorders
Altered locomotory and exploratory behavior is a hallmark of anxiety-like states in rodents. Subacute vitamin A supplementation at therapeutic doses increases oxidative stress in the hippocampus and decreases locomotory and exploratory activity, suggesting a link between oxidative stress, anxiety, and motor behavior. Similarly, Ocimum basilicum supplementation improves locomotory, exploratory, and anxiolytic behavior in mice, indicating that plant-derived compounds can modulate these behaviors.
Neurotoxicity and Environmental Exposure
Exposure to environmental toxicants can impair adult locomotory behavior. In zebrafish, acute ethanol exposure alters locomotory activity and exploratory behavior in a sex-specific manner. In earwigs, reduced-risk insecticides affect survival and locomotory behavior, demonstrating that neurotoxic compounds can disrupt motor function in non-target organisms.

How CRISPR Can Be Used to Study GO:0008344 adult locomotory behavior
Knockout
CRISPR knockout models are used to delete candidate genes and assess their role in adult locomotory behavior. For example, knocking out the foraging gene in Drosophila can test its requirement for feeding-induced locomotion. In C. elegans, knockout of npr-1 or tbh-1 can reveal their roles in adult foraging behavior.
Point Mutation
Point mutations introduced by CRISPR can mimic naturally occurring variants or disease-associated alleles. In zebrafish, point mutations in GABA receptor subunits can model altered ethanol sensitivity and locomotory responses. In mice, point mutations in DAT can affect dopamine signaling and locomotor activity.
Knock-in
Knock-in models allow precise tagging or replacement of genes to study their function in adult locomotory behavior. For instance, knocking in a fluorescent tag into the foraging locus in Drosophila enables visualization of its expression during locomotion. In C. elegans, knock-in of reporter genes can track environmental programming of foraging circuits.
Overexpression
Overexpression of candidate genes can test sufficiency in modulating adult locomotory behavior. In mice, overexpression of antioxidant enzymes such as SOD or catalase may protect against oxidative stress-induced decreases in locomotion. Overexpression of Ocimum basilicum-responsive genes could mimic the behavioral improvements seen with supplementation.
