Any kind of injury that occurs to the scalp or skull can be defined as head trauma. There are four types of head trauma and they are neuronal injuries, hemorrhages, vascular injuries and cranial nerve injuries. Symptoms of head trauma are leaking of cerebrospinal fluid, which can again lead to brain infection, depression in the head, an eye that is drifted to one side, wound/bruises on the scalp and skull fractures. Peer review refers to the work done during the screening of submitted manuscripts and funding applications. This process encourages authors to meet the accepted standards of their discipline and reduces the dissemination of irrelevant findings, unwarranted claims, unacceptable interpretations, and personal views. Publications that have not undergone peer review are likely to be regarded with suspicion by academic scholars and professionals.
