A Complex Diving-For-Food Task to Investigate Social Organization and Interactions in Rats.

For many species, where status is a vital motivator that can affect health, social hierarchies influence behavior. Social hierarchies that include dominant-submissive relationships are common in both animal and human societies. These relationships can be affected by interactions with others and with their environment, making them difficult to analyze in a controlled study.

Laser-Induced Brain Injury in the Motor Cortex of Rats.

A common technique for inducing stroke in experimental rodent models involves the transient (often denoted as MCAO-t) or permanent (designated as MCAO-p) occlusion of the middle cerebral artery (MCA) using a catheter. This generally accepted technique, however, has some limitations, thereby limiting its extensive use. Stroke induction by this method is often characterized by high variability in the localization and size of the ischemic area, periodical occurrences of hemorrhage, and high death rates.

Headache in Behçet's Disease.

Purpose Of Review: Our objective is to describe the various neurologic manifestations of Behcet's syndrome with special attention to headache syndromes.

Recent Findings: Most recent studies have focused on data collection to better characterize the relatively rare disorder of neuro-Behcets (NBD). In patients with Behcet's disease (BD) who are experiencing headache, most are primary headache disorders, specifically tension type or migraines.

Induction of Diffuse Axonal Brain Injury in Rats Based on Rotational Acceleration.

Traumatic brain injury (TBI) is a major cause of death and disability. Diffuse axonal injury (DAI) is the predominant mechanism of injury in a large percentage of TBI patients requiring hospitalization. DAI involves widespread axonal damage from shaking, rotation or blast injury, leading to rapid axonal stretch injury and secondary axonal changes that are associated with a long-lasting impact on functional recovery.
