What are organotypic brain slices?
Organotypic brain slices are cultured brain tissues that maintain the structural and functional characteristics of the in vivo environment.
How does the gene gun method work?
The gene gun method uses high-pressure gas to fire DNA-coated gold particles into targeted regions of tissue for genetic delivery.
What are the advantages of this method?
This method allows for precise targeting of specific regions and can transfect terminally differentiated cells effectively.
What applications does this technique have?
It can be used to study gene function, neuronal connectivity, and other neurobiological questions in a controlled manner.
How long does the procedure take?
Once mastered, the technique can be performed in a few hours over a period of three to four days.
