Rapid Golgi Stain For Dendritic Spine Visualization In Hippocampus And Prefrontal Cortex, Maya Frankfurt, Rachel E. Bowman Jan 2021

Rapid Golgi Stain For Dendritic Spine Visualization In Hippocampus And Prefrontal Cortex, Maya Frankfurt, Rachel E. Bowman

Psychology Faculty Publications

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 …

Hemispheric Processing In Conventional Metaphor Comprehension: The Role Of General Knowledge, Stephen W. Briner, Michael C. Schutzenhofer, Sandra M. Virtue Jun 2018

Hemispheric Processing In Conventional Metaphor Comprehension: The Role Of General Knowledge, Stephen W. Briner, Michael C. Schutzenhofer, Sandra M. Virtue

Psychology Faculty Publications

This study explored the relation between general knowledge and the hemispheric processing of metaphoric expressions in college age students. We hypothesized that prior knowledge influences how the hemispheres process metaphors in these individuals. In this study, 97 young (college-aged) adults completed a general knowledge and vocabulary test, and were then divided into high-knowledge/high-vocabulary and low-knowledge/low-vocabulary groups. Next, participants viewed word pairs consisting of conventional metaphors, novel metaphors, word pairs with a literal meaning, and unrelated word pairs. The first word in each pair was presented centrally, and the second was presented to the right visual field-left hemisphere (rvf-LH) or the …

Sex Differences In Chronic Stress Effects On Cognition In Rodents, Victoria N. Luine, Juan Gomez, Kevin D. Beck, Rachel E. Bowman Jan 2017

Sex Differences In Chronic Stress Effects On Cognition In Rodents, Victoria N. Luine, Juan Gomez, Kevin D. Beck, Rachel E. Bowman

Psychology Faculty Publications

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 …

On April 14th, 2016, Animal Behavior and Cognition lost its Editor-in-Chief. But the scientific community and the friends and colleagues of Stanley ‘Stan’ Kuczaj III lost so much more. As many know, Stan began his career in Developmental Psychology, making enormous contributions in the area of language development, but became best known for his many innovative contributions in the area of marine mammal behavior. Stan founded Animal Behavior and Cognition because he was deeply passionate about research with a broad range of topics concerning animal behavior, animal cognition, and animal welfare. He was equally passionate about the idea that science …

Tackling Ocd: Talk Is Not Cheap!, Christina J. Taylor Jan 2010

Tackling Ocd: Talk Is Not Cheap!, Christina J. Taylor

Psychology Faculty Publications

Cognitive Therapy offers techniques to help identify ways and patterns of thinking that produce distress, negative behavior, and poor motivation. Cognitive techniques can help improve an individual’s motivation to tackle their OCD, help change their reaction to and interpretation of their obsessions, and help them to cope with the anxiety they experience when they carry out an exposure and response prevention regimen.

Aged Rats: Sex Differences And Responses To Chronic Stress, Rachel E. Bowman, Neil J. Maclusky, Samantha Diaz-Weinstein, Mark C. Zrull, Victoria N. Luine Dec 2006

Aged Rats: Sex Differences And Responses To Chronic Stress, Rachel E. Bowman, Neil J. Maclusky, Samantha Diaz-Weinstein, Mark C. Zrull, Victoria N. Luine

Psychology Faculty Publications

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 …

Self-Efficacy, Jennifer T. Gosselin, James E. Maddux Jan 2003

Self-Efficacy, Jennifer T. Gosselin, James E. Maddux

Psychology Faculty Publications

The study of self-efficacy is concerned with understanding this important aspect of self and identity—people's beliefs about their personal capabilities and how these beliefs influence what they try to accomplish, how they try to accomplish it, and how they react to successes and setbacks along the way.

Chronic Restraint Stress Enhances Radial Arm Maze Performance In Female Rats, Rachel E. Bowman, Mark C. Zrull, Victoria N. Luine Jun 2001

Chronic Restraint Stress Enhances Radial Arm Maze Performance In Female Rats, Rachel E. Bowman, Mark C. Zrull, Victoria N. Luine

Psychology Faculty Publications

Effects of chronic restraint stress (21 and 28 days) on physiological and behavioral parameters in female rats were examined. Total (bound and free) and free corticosterone (CORT) levels were measured at different time points during the stress period. Higher total CORT levels were observed in stressed rats during the stress period but returned to baseline at 15 days poststress. Additionally, free CORT levels decreased across the stress period. Estrous cyclicity was monitored daily in all animals. Stress had no apparent effects on estrous cyclicity, in rats with either normal length or elongated estrous cycles, but stressed females gained less weight …
