De novo hippocampal neurogenesis contributes to functional recovery following traumatic brain injury (TBI). Enriched environment (EEN) can improve the outcome of TBI by positively affecting neurogenesis. Blast induced traumatic brain injury (bTBI) characterized by memory impairment and increased anxiety levels, is a leading cause of chronic disability among soldiers. Using a rodent model of bTB...

background and objective: identifying the details of the injurious effects of alcohol seems to be decisive in nowadays with growing abuse of the substance. this study mainly aimed to assess the adverse effects of ethanol on the recalling of information in the wistar rats. materials and methods: male wistar rats (pasteur institute of iran) were evaluated using the novelty seeking behavior based ...

The role of salt intake in the development of hypertension is prominent, but its mechanism has not been fully elucidated. Our aim was to examine the effect of transient salt intake during the prehypertensive period in hypertensive model animals. Dahl salt-sensitive rats and spontaneously hypertensive rats were fed from 6 to 14 weeks with low-salt (0.12% NaCl), normal-salt (0.8% NaCl), high-salt...

Functional neuroimaging studies of traumatic brain injury (TBI) have demonstrated altered neural recruitment, specifically within prefrontal cortex (PFC). This is manifest typically as increased recruitment of homologous regions of PFC (e.g., right ventrolateral PFC during performance of a verbal working memory task, possibly in response to damage involving the left PFC). The behavioral correla...

BACKGROUND Detecting malingering or exaggeration of impairments in brain function after traumatic brain injury is of increasing importance in neuropsychological assessment. Lawyers involved in brain injury litigation cases routinely coach their clients how to approach neuropsychological testing to their advantage. Thus, it is important to know how robust assessment methods are with respect to s...

The authors used a computerized neurocognitive assessment tool (CNS Vital Sign, CNSVS) in a pediatric trauma patient in the emergency department to examine neurocognitive functioning in children and adolescents. They compared a mild traumatic brain injury (mTBI) group with orthopedic injury controls (OICs). CNSVS was developed to rapidly screen cognitive abilities and has high adequate concurre...

Bilateral carotid artery occlusion followed by reperfusion produced significant cerebral infarction and impaired short-term memory, motor co-ordination and lateral push response. Individual pretreatments with chlorophyll and aqueous extracts of B. monniera and V. wallichii markedly attenuated ischaemia-reperfusion induced cerebral injury in terms of decreased infarct size, increase in short-ter...

Evidence suggests that a history of head trauma is associated with memory deficits later in life. The majority of previous research has focused on moderate-to-severe traumatic brain injury (TBI), but recent evidence suggests that even a mild TBI (mTBI) can interact with the aging process and produce reductions in memory performance. This study examined the association of mTBI with memory and th...
