In Parkinson's disease and movement disorders in general, sensitive and reliable behavioral assays are essential for testing novel potential therapeutics. Here, we describe a manageable battery of sensorimotor tests for mice that are sensitive to varying degrees of injury to the nigrostriatal system and useful for preclinical studies.

Sensorimotor Stage I: Substages 1 to 3
0 Views •
2026
Piaget’s theory describes cognitive development as a sequence of stages. The first is the sensorimotor stage, which extends from birth to approximately two years. During this period, infants gain knowledge mainly through sensory experiences and motor actions. Over time, behavior progresses from automatic reflexes toward increasingly intentional and goal-oriented actions. The first three substages show the early part of this transition.Substage 1: Reflexive SchemesReflexive schemes span the...

Piaget’s sensorimotor stage describes cognitive development from birth to approximately two years. During this stage, infants progress from reflexive behavior toward intentional action and early symbolic thought. Substages four through six show major advances in problem-solving, experimentation, and mental representation.Substage 4: Coordination of Secondary Circular ReactionsFrom approximately 8 to 12 months, infants begin coordinating previously learned behaviors to achieve specific goals.

The cranial mesenchyme undergoes dramatic morphogenic movements that likely provides a driving force for elevation of the neural folds1,2. Here we describe a simple ex vivo explant assay to characterize the cellular behaviors of the cranial mesenchyme during neurulation. This assay has numerous applications including being amenable to pharmacological manipulations and live imaging analyses.
FAQs
Coordination depends on integrating signals from multiple sensory channels rather than treating each input in isolation. Visual, auditory, olfactory, gustatory, and somatosensory information is combined in the brain and translated into cranial nerve outputs. This organization aligns perception with orienting, feeding, vocalizing, or facial expression, linking neural processing to observable behavior.
Brainstem circuits organize important routes between integrated sensory information and motor output. Cranial nerve pathways then help direct actions involving the head, face, eyes, and mouth. Their coordination supports behavior that requires rapid alignment between what an organism detects and how it responds, including orientation, feeding, vocalization, and facial expression.
Adaptive responses depend on matching incoming information with an appropriate action. Cranial sensorimotor function contributes to this matching by connecting sensory processing with movements and expressions that affect interaction with the environment. Studying the coordination helps explain how neural activity supports behavior rather than examining perception or movement as isolated processes.
Disruptions may interfere with communication, movement, perception, or adaptive responses because these behaviors depend on coordinated sensory processing and motor control. The consequences can be examined through changes in actions involving the head, face, eyes, or mouth. This connection makes cranial sensorimotor function relevant to understanding how altered neural activity can affect behavior.
Researchers link neural activity with observable behaviors that depend on cranial sensory and motor systems. They can examine how processing relates to orienting, feeding, vocalizing, facial expression, communication, movement, perception, and adaptive responses. This approach connects activity in neural pathways and brainstem circuits with the behavioral outcomes those systems help organize.
Orienting, feeding, vocalizing, and facial expression are informative outputs because each requires sensory information to guide actions involving the head, face, eyes, or mouth. Communication, movement, perception, and adaptive responses also provide relevant behavioral context. Examining these outputs helps researchers assess how neural processing is expressed through behavior and environmental interaction.
Behavior depends on continuous relationships between neural processing, bodily action, and interaction with the environment. Cranial systems make these relationships visible through perception, movement, vocalization, feeding, facial expression, and orientation. Consequently, studying them gives behavioral research a way to connect neural mechanisms with communication, adaptive responses, and other observable actions.
