Weight Drop (Marmarou) Model

The weight drop (Marmarou) model is a widely recognized and extensively utilized preclinical tool designed to mimic human diffuse traumatic brain injury (DTBI). Unlike models that induce localized damage, the Marmarou model focuses on generating widespread, bilateral neural injury, which is critical for understanding the complexities of TBI that result from acceleration-deceleration and rotational forces.

The foundational principle of the model involves a precisely controlled impact. An anesthetized animal's head is positioned, and a free-falling weight is dropped onto a metal disc placed on the skull. This disc is crucial as it distributes the impact force, preventing skull fractures and ensuring the kinetic energy translates into diffuse brain deformation, rather than a focal contusion. The severity of the injury can be finely modulated by adjusting parameters such as the weight's mass and the height from which it is dropped, allowing for the induction of a spectrum of injuries from mild concussive forces to more severe diffuse damage.

The injury induced by the Marmarou model consistently produces a cascade of pathological events closely resembling those seen in human DTBI. These include Diffuse Axonal Injury (DAI), characterized by widespread axonal damage throughout the white matter tracts of the brain, including the corpus callosum and brainstem. Beyond DAI, the model leads to neuronal cell death, reactive astrogliosis, microglial activation, and disruption of the blood-brain barrier (BBB). Furthermore, studies consistently show the development of cytotoxic brain edema and hemorrhages. These pathological changes underpin the observable functional deficits, including impairments in motor function, learning, and memory, which are extensively characterized through various behavioral assays. The model's capacity to induce such a comprehensive array of clinically relevant outcomes makes it an indispensable platform for preclinical research into TBI mechanisms and the evaluation of potential therapeutic strategies.
