nVue-nVision - Main applications

The nVue miniscope platform is designed to enable minimally invasive, longitudinal, cellular-resolution imaging in freely behaving animals paired with synchronized behavioral tracking, for precise spatio-temporal mapping of local brain activity in relation to behavior.

Common applications of miniscope imaging

Single modality imaging (nVue)

  • Calcium imaging (GCamp, RCamp)

    • Enables optical detection of action potential-associated intracellular Ca²⁺ transients.

    • Captures population-level activity from excitatory or inhibitory neurons.

    • Applied in studies of cortical and subcortical circuit function during task performance, rest, or spontaneous activity.

  • Neurotransmitter imaging (dLight, GRAB, iGluSnFR)

    • Measures extracellular neurotransmitter dynamics such as dopamine, glutamate, serotonin, or acetylcholine in real time.

    • Useful for studying neuromodulatory control of motivation, reinforcement, attention, and emotional state.

    • Applied in pharmacological studies and addiction research.

  • Dual-signal imaging

    • Simultaneous recording of neural activity and/or neuromodulatory signals using spectrally distinct fluorescent indicators.

    • Allows dissection of causal relationships between neurotransmitter release and downstream circuit responses.

    • Ideal for multi-population or multi-pathway functional mapping within the same brain region.

    • Allows for static/static, static/dynamic and dynamic/dynamic recordings.

  • Longitudinal neural ensemble tracking

    • Supports stable, chronic recordings from the same neuronal population across days or weeks.

    • Enables investigation of learning-related plasticity, disease progression, and memory consolidation.

    • Facilitates studies of neuronal identity retention, population coding dynamics, and circuit adaptation.

  • Cerebral blood flow imaging

    • Investigates vascular responses to circuit activation.

    • Studies of neurovascular impairment in aging, stroke, or models of neurodegenerative diseases.

    • Evaluates metabolic load and vascular plasticity in learning or disease contexts.

Multimodal imaging (nVue + nVision)

The synchronization of both nVue and nVision cameras enable the real time combination of neuronal signal imaging with behavior.

  • Brain-behavior coupling

    • Enables real-time correlation between neuronal ensemble dynamics and specific motor, cognitive, or emotional behaviors.

    • Critical for identifying functional neural correlates of decision-making, navigation, or social interaction.

    • Provides high temporal resolution synchronization of neural and behavioral data streams.

  • Learning and memory encoding

    • Tracks how ensemble activity evolves across repeated exposure to environmental stimuli or operant tasks.

    • Used to reveal circuit-level mechanisms of learning phases (acquisition, consolidation, extinction).

    • Supports causal inference in behavior-driven plasticity through repeated exposure paradigms.

  • Neuropsychiatric and neurological disease models

    • Enables quantitative phenotyping of circuit dysfunction in models of depression, PTSD, anxiety, addiction, Alzheimer’s, and Parkinson’s disease…

    • Allows evaluation of therapeutic interventions (pharmacologic, genetic) on both behavior and brain function.

    • Ideal for longitudinal biomarker discovery at the level of cellular networks.

  • Social and ethologically relevant behaviors

    • Permits imaging during unrestrained behaviors such as social investigation, aggression, parental care, or environmental exploration.

    • Supports analysis of circuits involved in emotional valence, threat response, or affiliative behavior.

    • Especially relevant in translational studies of neurodevelopmental or affective disorders.
