Minipiglerde Kortikal Elektrofizyoloji Kaydı için Yumuşak Elektrokortikografi Dizisinin Subdural İmplantasyonu

Executive Industry Relevance

Subdural implantation of soft electrocorticography (ECoG) arrays in minipigs enables high-fidelity cortical electrophysiology recordings in a translationally relevant large-animal model. This capability supports early-stage target validation and mechanistic de-risking for CNS drug discovery, particularly in auditory and neuroprosthetic research. The approach enhances predictive confidence for portfolio decisions by bridging preclinical and translational neuroscience workflows.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables direct interrogation of cortical circuit function in a large-animal model.
• Supports mechanistic de-risking by capturing stimulus-evoked neuronal activity.
• Facilitates functional target validation for auditory and CNS pathways.
• Provides quantitative electrophysiological endpoints for hypothesis testing.

Screening & Assay Development

• Establishes a validated platform for longitudinal cortical activity monitoring.
• Delivers reproducible, quantitative readouts for compound or device evaluation.
• Supports assay standardization across preclinical studies in translational models.
• Enables screening of neuromodulatory interventions with high temporal resolution.

Translational & Preclinical Research

• Aligns preclinical electrophysiology with human-relevant cortical mapping.
• Facilitates continuity from discovery through preclinical validation in large animals.
• Supports risk-adjusted advancement of CNS assets with translational biomarkers.
• Provides a platform for evaluating neuroprosthetic and auditory therapeutics.

Pipeline & Workflow Integration

This method integrates into the discovery-to-preclinical continuum by enabling direct cortical recordings in a model with human-like neuroanatomy, supporting both mechanistic studies and translational biomarker development.
