Golgi impregnation, using the Golgi staining kit with minor adaptations, is used to impregnate dendritic spines in the rat hippocampus and medial prefrontal cortex. This technique is a marked improvement over previous methods of Golgi impregnation because the premixed chemicals are safer to use, neurons are consistently well impregnated, there is far less background debris, and for a given region, there are extremely small deviations in spine density between experiments. Moreover, brains can be accumulated after a certain point and kept frozen until further processing. Using this method any brain region of interest can be studied. Once stained and cover …

Chronic stress causes deleterious changes in physiological function in systems ranging from neural cells in culture to laboratory rodents, sub-human primates and humans. It is notable, however, that the vast majority of research in this area has been conducted in males. In this review, we provide information about chronic stress effects on cognition in female rodents and contrast it with responses in male rodents. In general, females show cognitive resilience to chronic stressors which impair male cognitive function using spatial tasks including the radial arm maze, radial arm water maze, Morris water maze, Y-maze and object placement. Moreover, stress often …

Animal Cognition, The Importance Of Touch, And The Cit, Deirdre Yeater
Presidential Seminar on the Catholic Intellectual Tradition
A presentation of Professor Yeater's incorporation in her class PSCC103 of 5 in- class discussions comparing human and non-human species, particularly dolphins, with an emphasis on the Catholic Intellectual Tradition and the importance of touch. PSCC-103, The Human Community: The Individual and Society, is a 3 credit course which engages students in a study of the relationship between psychology – the science of human behavior and mental processes, and the Catholic intellectual tradition – which is characterized by rigorous intellectual inquiry and an openness to scientific ideas. This course aims to help us understand ourselves as human persons, as well …

Cognitive, as well as physiological, sex differences exist in young adult rats under both basal conditions and following chronic stress; however, few studies have examined whether sex differences remain in aged subjects and whether responses to stress are altered. We compared aged male and female Fischer 344 rats (21.5 months at testing) without stress and when given 21 days of restraint for 6 h/day on locomotion, anxiety-related behaviors, object recognition (non-spatial memory), object placement (spatial memory), body weight and serum steroid hormone levels. Control (unstressed) females had lower levels of estradiol and testosterone and higher corticosterone than males, and stress …
