Overview
This protocol outlines the dissection, transfection via electroporation, and culture of mouse hippocampal and cortical neurons. These cultures facilitate studies on axon outgrowth, synaptogenesis, and dendritic spine analysis.
Key Study Components
Area of Science
- Neuroscience
- Cell Biology
- Developmental Biology
Background
- Hippocampal and cortical neurons are crucial for studying neuronal polarization.
- These neurons can form distinctive axons and dendrites on a substrate.
- Culturing allows for the observation of synapse formation and function.
- Short-term cultures are ideal for axon outgrowth studies.
Purpose of Study
- To demonstrate a technique for isolating and maintaining cultures of cortical and hippocampal neurons.
- To study the dynamics of fluorescent fusion proteins during neuronal development.
- To investigate early and late developmental events in neurons.
Methods Used
