Theses and Dissertations
The pathology which results from traumatic brain injury (TBI) have long been believed to be immediate and irreversible. However, recently it has been shown that, although the primary effects are virtually unavoidable, the secondary effects manifest themselves through biochemical processes set in motion at the time of the injury. These events are frequently mediated through the process of excitotoxicity, which results from a widespread release of excitatory neurotransmitters. These neurotransmitters go on to activate both ionotropic and metabotropic receptors. The signal transduction initiated through these receptor populations gives rise to changes in gene expression.
One result of this release of …
