This video and protocol demonstrate how to implant a glass-covered cranial window in rodents. These preparations can be used for chronic in vivo two-photon imaging of the neocortex over time scales of months. It may also be used for other types of imaging, including optical intrinsic signal imaging.

Blood-brain barrier disruption aids the delivery of certain drugs to the brain. Mannitol delivered intra-arterially shrinks cells surrounding blood vessels in order to physically disrupt the barrier.
FAQs
Stereotaxic coordinates convert an intended brain location into a reproducible target for instrument placement. In a secured animal, the frame stabilizes the head while anatomical coordinates guide the craniotomy and subsequent positioning. This spatial control supports localized delivery or recording and makes findings more comparable across animals.
Instrument selection determines what researchers can measure or manipulate. Injection needles and cannulas support localized delivery, whereas recording electrodes monitor electrical activity. Tissue sampling provides material for analysis. Matching the device to the experimental question therefore links the surgical intervention to an interpretable neuroscience outcome.
Anesthesia, sterile technique, physiological monitoring, and postoperative care support both animal welfare and experimental validity. Anesthesia enables controlled surgery, while monitoring helps maintain relevant physiological conditions. Sterility and follow-up support safer recovery and better data quality when researchers study neural function, behavior, or disease-related changes.
Researchers can select the intervention according to the information they need from the brain. Localized delivery is suited to studying drug effects, recording electrodes to examining electrophysiological activity, and tissue sampling to investigating neural structure or disease-related changes. This alignment clarifies what each experiment can reveal.
Rat Brain Surgery connects physical access to the brain with measurements of neural circuits and behavior. By placing an intervention or recording site at a defined anatomical location, investigators can relate localized neural activity or manipulation to observed behavioral effects. The model also supports research on drug actions and neurological disorders.
Depending on the instrument and objective, outcomes can include localized delivery, electrophysiological recordings, tissue samples, or behavioral and disease-related observations. These outputs answer different questions: recordings address function, sampling addresses tissue, and delivery tests effects in a defined region. Interpretation requires linking the surgical target and intervention type to the measured outcome.
