Mechanisms underlying secondary cell death due to Traumatic brain injury (TBI) are poorly understood. Recent advances in magnetic resonance spectroscopy (MRS) allow us to observe highly resolved metabolic changes in the brain after the injury. MRS offers a unique window to identify the severity of the injury, outcome of the injury and secondary insult. Here in this work animal injury of the blast model is conducted and we are also seeing a similar trend which shows significant reduction in NAA/(total Choline ) concentration. Our histochemistry results are also confirming the damage of neural nucleus at 72 hrs after the injury.
