Development of Brief Memory Tests for Use with Pet Dogs

Brief memory tasks for use with pet dogs were developed using radial arm maze performance as a standard comparison measurement of memory capacity. Healthy pet dogs were first tested in a radial arm maze, where more errors made in completing the maze indicated poorer memory. These dogs were later tested with five novel memory tests, three of which utilized a treat placed behind a box with an identical distracter nearby. The treat placement was shown to each dog, and a 35 second delay, a 15 second delay with occluder, or a 15 second delay with room exit was observed before the dog could approach and find the treat. It was found that errors on the delayed match to sample (35 second delay) and occluder/object permanence (15 second delay with occluder) tasks were significantly positively correlated with the average number of errors made in the 8th trial of the radial arm maze (r =.58, p<.01** and r =.49, p<.05*, respectively) indicating that these new brief tests can reliably be used to assess memory in pet dogs.

Head Trauma in Professional Football Players: Implications for the Brain, the Game, and Society

Sports related concussions, or mild traumatic brain injuries (mTBI), have recently increased in prevalence, and thus gained a great deal of recognition from the public and the media. While the acute symptoms associated with concussions are well known, which include headaches, dizziness, vomiting, and fatigue, recent research has indicated that there can be severe chronic consequences of multiple conditions. Most notably, a disease called Chronic Traumatic Encephalopathy (CTE) has been linked to multiple mTBIs, which produces symptoms similar to Alzheimer's disease and dementia, in addition to personality changes, increased suicidality, and in some cases death. This knowledge has led the NFL to take steps to protect their players, and increase both the understanding and awareness of the problems associated with multiple concussions. This comes with many problems, however, as players and fans alike are quick to resist any type of change to the rules or policies present in football, in fear that it may damage the integrity of the game. The NFL is thus forced into a difficult position, and must balance public opinion and player safety. There are things that can be done, however, that do not threaten the game itself, such as investing in concussion research and safety equipment design that will more effectively protect the brain from concussions.

How many new friends can a menopausal rat remember? Developing a new task of social recognition with an increasing working memory load

Memory as whole is impacted by changes associated with aging and menopause. Different memory types are often tested preclinically utilizing rats in different task paradigms. Most studies have focused on understanding social recognition or working memory, however these memory types have yet to be studied together. This thesis focuses on the process of creating and testing a new social recognition task that incorporates a working memory load. We tested different types of previously used social recognition paradigms with an increasing load and through qualitative and quantitative observations the task was modified until a final task was developed for a social working memory study. Young female rats were tested in this task in progressive, meaning a chronologically increasing load and nonprogressive, meaning non-chronological increase in load cognitions. It was found that young female rats had the ability to distinguish between the familiar and novel conspecifics before memory load exceeded four familiar and one novel conspecifics. Once validated through future studies, this task may be utilized to understand the impact of different types of menopause on social working memory.
