High-Frequency Stimulation to Enhance Neuronal Activation and Neurogenesis in the Mouse Dentate Gyrus

Executive Industry Relevance

High-frequency stimulation of the mouse dentate gyrus provides a controlled platform to interrogate neuronal activation and neurogenesis, supporting mechanistic de-risking in CNS target validation. This approach enables quantitative assessment of synaptic plasticity and neurogenic responses, informing early-stage portfolio decisions for neurotherapeutic discovery. The method's reproducibility and quantitative outputs position it as a valuable tool for translational neuroscience pipelines.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables direct interrogation of neuronal activation and synaptic strengthening in a defined brain region.
• Supports functional target validation by quantifying neurogenesis and synaptic plasticity markers.
• Facilitates mechanistic de-risking for CNS targets by linking stimulation to measurable biological outcomes.

Screening & Assay Development

• Establishes a validated in vivo system for evaluating neurogenic and synaptic responses to stimulation.
• Provides standardized protocols for reproducible measurement of neuronal activation using C-fos and BrdU labeling.
• Generates quantitative outputs suitable for downstream compound screening or genetic perturbation studies.

Translational & Preclinical Research

• Aligns with disease-relevant mechanisms by modeling neurogenesis and synaptic plasticity in vivo.
• Supports continuity from discovery to preclinical validation by enabling assessment of functional integration of new neurons.
• Offers predictive value for cognitive enhancement strategies in neurodegenerative or neuropsychiatric models.
