This video demonstrates the technique of assessing neuronal death in rhinal cortex-hippocampus organotypic slices. Neuronal death occurs via evolving epileptic seizures — resembling in vivo epilepsy — and is detected through dual-staining of the dead cells using propidium iodide and immunofluorescence.

University of Notre Dame, IN The Guide for the Care and Use of Laboratory Animals ("The Guide") states that pain assessment and alleviation are integral components of the veterinary care of laboratory animals. The definition of anesthesia is the loss of feeling or sensation. It is a dynamic event involving changes in anesthetic depth with respect to an animal's metabolism, surgical stimulation, or variations in the...
FAQs
A rapid increase in intracranial pressure can compress brain tissue and reduce cerebral perfusion, limiting the blood flow needed to sustain neural activity. As pressure-related injury progresses, researchers can examine changes in neurological function alongside physiological measurements. This relationship makes intracranial pressure and cerebral perfusion important variables when interpreting experimental outcomes.
Brainstem reflexes and spontaneous respiration provide functional indicators of severe neurological failure. Their loss helps researchers assess whether brainstem activity has been eliminated, rather than relying on a single physiological measurement. Recording these endpoints alongside other monitoring data strengthens confirmation procedures and improves the scientific interpretation of neurological and systemic changes.
The model supports investigation of consequences beyond the nervous system, including inflammatory responses and organ dysfunction. Loss of brain and brainstem function can therefore be studied as a whole-body process rather than only as a neurological event. These observations help connect neurophysiological changes with downstream effects in peripheral organs and tissues.
Careful physiological monitoring is essential because the model produces neurological and systemic changes that must be distinguished, documented, and compared consistently. Researchers monitor relevant physiological states and confirm the loss of brain and brainstem function using standardized criteria. Consistent monitoring improves reproducibility and helps prevent ambiguous findings from undermining experimental conclusions.
Neuroscience researchers use this model when they need to examine the consequences of irreversible loss of brain and brainstem function under controlled experimental conditions. Applications include studying neurophysiological changes, inflammatory responses, and organ dysfunction. It can also provide context for investigating how brain death affects organs that may be considered for donation.
Brain death induction allows researchers to examine how the physiological state associated with brain death affects potential donor organs. Measurements of organ dysfunction and inflammatory responses can reveal systemic changes relevant to organ preservation and evaluation. Standardized confirmation and rigorous monitoring are necessary so that observed organ effects can be interpreted reliably and ethically.
