We describe a method to prepare organotypic hippocampal slices that can be easily adapted to other brain regions. Brain slices are laid on porous membranes and culture media is allowed to form an interface. This method preserves the gross architecture of the hippocampus for up to 2 weeks in culture.

This video demonstrates the development of a 3D co-culture system. Mouse brain slices are placed on a membrane, and fluorescently labeled human brain tumor cells are allowed to grow on it. Once the system is ready, it is stained for imaging.
FAQs
Energy substrates supply metabolic support, while essential salts help maintain the ionic conditions required by living neural tissue. Amino acids contribute to the medium’s nutritional balance, and buffering components help stabilize pH. Together, these ingredients create a chemically supportive environment for slices, making tissue health dependent on more than any single additive.
These conditions shape whether cells remain in a suitable physiological environment after removal from the body. pH and osmolarity reflect chemical and solute balance, whereas oxygen availability supports ongoing tissue maintenance. Small changes in any of these variables can alter tissue health and recorded responses, so consistent control is central to reproducible neuroscience experiments.
Supplements can promote neuronal and glial survival, extending the cellular populations that remain available for study. Their inclusion therefore affects more than simple viability: it can help preserve the cellular organization needed to examine neural circuits, development, plasticity, injury, or disease. Because composition influences tissue health, supplements should be treated as experimental variables.
Maintaining the arrangement of cells and local synaptic connections lets investigators examine neural responses within a relatively intact tissue context. This is especially valuable when studying circuit behavior, developmental changes, or plasticity, because observations can reflect interactions among nearby neural elements rather than isolated cellular responses. Medium handling consequently affects physiological relevance.
Handling should preserve the medium’s balanced composition and the conditions required for tissue health, including appropriate pH, osmolarity, and oxygen availability. Researchers also select whether to include supplements that support neuronal and glial survival. Keeping these features consistent across preparations helps maintain slice viability and reduces variation in experimental outcomes, including recorded neural responses.
The preparation can support observations of neural circuits and local synaptic relationships while tissue remains viable outside the body. Researchers can therefore examine cellular responses in controlled ex vivo conditions and relate those responses to development, plasticity, injury, or disease. The quality of the medium influences whether resulting measurements remain physiologically relevant.
These preparations support studies of neural circuits, development, synaptic plasticity, injury, and disease. The medium is important across these applications because tissue condition determines whether cellular architecture and local connections remain suitable for investigation. Thus, the same preparation can address different questions when its composition and handling are controlled.
