Перфорированные патч-зажим записи из мышей Обонятельные сенсорные нейроны в неповрежденном нейроэпителии: Функциональный анализ нейронов выражая идентифицированного одоранта рецептор

Overview

This study focuses on measuring the physiological properties of olfactory sensory neurons (OSNs) using perforated patch-clamp techniques. By analyzing OSNs in an intact olfactory epithelium from gene-targeted mice, researchers can characterize membrane properties and responses to specific odorants.

Key Study Components

Area of Science

• Neuroscience
• Olfaction

Purpose of Study

• To measure changes in membrane properties of OSNs in response to odorants.
• To characterize functional properties of OSNs at the membrane level.
• To address key questions in the field of olfaction.

Methods Used

• Dissection of the olfactory epithelium.
• Transfer of the epithelium into a perfused chamber.
• Microscopic selection of OSNs of interest.
• Patch clamping of the dendritic knob while stimulating with odorants.
