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

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.

Mouse models have become increasingly popular in studies of behavioral neuroscience. As models advance, it is important to develop sensitive behavioral measures specific to the mouse. This protocol describes the Pasta Matrix Reaching Task, which is a skilled motor task for use in mouse models of stroke.

A fully automated protocol for rodent operant conditioning is proposed. The protocol relies on precise temporal control of behavioral events to investigate the extent to which this control influences neural activity underlying sensorimotor integration and cognitive control experiments.

Different receptor systems provide complementary information for movement control. Skin receptors signal aspects of contact, while muscle and joint receptors contribute information about body position and movement. Visual input supports perception of the environment, and inner-ear signals contribute to balance. The brain and spinal cord integrate these sources so motor commands can be coordinated with current sensory conditions.
Sensory feedback allows the nervous system to compare ongoing body and environmental information with the demands of an action. Signals from receptors can therefore influence how much force a movement requires, when muscles should act, and how posture or balance should be adjusted. This continuous updating helps maintain coordinated behavior rather than relying only on an initial motor command.
Adaptation through learning shows that sensorimotor circuits are not limited to fixed responses. Studying how behavior changes with experience can reveal how neural circuits support increasingly effective coordination between perception and action. In neuroscience, this perspective connects immediate movement control with longer-term changes in performance, making learning an important context for interpreting sensorimotor behavior.
Researchers and clinicians can examine reflexes, coordination, proprioception, and reaction time. Together, these measures sample different aspects of performance, including rapid responses, organized movement, awareness of body position, and the speed of responding to sensory information. Considering several measures provides a broader profile than relying on a single test and can help identify changes in neurological function.
Measures of sensorimotor performance help characterize how neurological disorders affect movement-related abilities. Reflexes, coordination, proprioception, and reaction time can provide observable indicators for comparing function across individuals or tracking changes over time. These results help connect clinical or behavioral findings with the neural circuits that support perception, motor control, and coordinated action.
Sensorimotor findings can guide rehabilitation by identifying which aspects of movement or sensory control require attention and by providing measures for evaluating change. The same principles inform assistive technology development, where understanding the relationship between sensory input and motor output can help shape systems intended to support movement, coordination, posture, or balance.
