Overview

This study presents an in vivo two-photon imaging protocol for examining the cerebral cortex of neonatal mice. The method allows researchers to analyze the dynamics of cortical neurons, their molecular mechanisms, and changes associated with disease models.

Key Study Components

Area of Science

• Neuroscience
• Developmental Biology
• Imaging Techniques

Background

• Focus on the developmental dynamics of cortical neurons.
• In vivo imaging of living neonatal mice enables real-time analysis.
• Addresses questions related to neuron socket formation and overall neuronal dynamics.

Purpose of Study

• To understand the mechanisms controlling neuronal dynamics in healthy and disease states.
• To provide insights into morphological changes of neurons over time.

Methods Used

• The platform involves in vivo two-photon microscopy.
• Neonatal mice, specifically post-natal day five pups, are used as the biological model.
• Key steps include craniotomy preparation and the application of a cranial window for imaging.
• Imaging involves capturing Z-stack images at specified intervals.

Main Results

• Clear images of dendritic morphology were obtained, revealing dynamic changes over time.
• Neuronal responses, such as the retraction and elongation of dendritic tips, were documented within hours.
• Findings illustrate the importance of maintaining the dura intact during procedures.

Conclusions

• This protocol enables detailed insights into the processes governing neuronal development and dynamics.
• It highlights the potential for studying disease models through morphological analysis of living neurons.
