Neonatal Isolation Stress Inhibits Pre-Weaning Weight Gain And Mild-Stressor Induced Locomotor Activity In Early Adolescent Male And Female Rats, Peter Villavecchia, Mindy Miserendino
Neonatal Isolation Stress Inhibits Pre-Weaning Weight Gain And Mild-Stressor Induced Locomotor Activity In Early Adolescent Male And Female Rats, Peter Villavecchia, Mindy Miserendino

The present study looked at the effects of neonatal isolation, an early life stress experience, in male and female early adolescent rats, an age which is underrepresented in the early stress literature. Four stress-sensitive indices were assessed: weight gain during the pre-weaning period, open field activity, and locomotor activity in response to two mild stressors: exposure to a novel environment, and a single IP saline injection. Rats in the neonatal isolation condition were removed from dam and littermates on postnatal days 2-9 in accord with the procedure used by Kehoe et al. (1995); behavioral testing occurred on PN25-PN30 during …

Prior research has demonstrated the reliability and validity of the Neurological Predictor Scale (NPS) in relation to childhood brain tumor survivor outcomes; however, its use has not been examined in adult long-term survivors. The current study examines the concurrent validity of the NPS with long-term intellectual and adaptive outcomes in adult survivors of childhood brain tumors relative to individual variables alone. A total of 68 adult survivors of childhood brain tumors (M = 24 years old, SD = 4) almost 16 years post diagnosis (SD = 6) completed intellectual evaluations using the Wechsler Abbreviated Scale of Intelligence (WASI). Survivors' adaptive …

The Boston Qualitative Scoring System (BQSS) was used as a method to examine executive skills on the Rey-Osterrieth complex figure (ROCF). Young adult survivors of childhood brain tumor (N = 31) and a demographically-matched comparison group (N = 33) completed the ROCF copy version and Grooved Pegboard, and informants were administered the Scales of Independent Behavior-Revised (SIB-R) and Behavior Rating Inventory of Executive Function (BRIEF). Survivors had significantly lower BQSS planning and SIB-R community living skills and greater perseveration. Mediation analyses found that BQSS planning skills mediate the relationship between group and community living skills. Convergent findings of the BRIEF …

Objective: We examined the nature of verbal memory deficits and the possible hippocampal underpinnings in long-term adult survivors of childhood brain tumor. Method: 35 survivors (M=24.10±4.93 years at testing; 54% female), on average 15 years post-diagnosis, and 59 typically developing adults (M=22.40±4.35 years, 54% female) participated. Automated FMRIB Software Library (FSL) tools were used to measure hippocampal, putamen, and whole brain volumes. The California Verbal Learning Test – Second Edition (CVLT-II) was used to assess verbal memory. Results: Hippocampal (F(1,91)=4.06, ηp2=.04), putamen (F(1,91)=11.18, ηp2=.11), and whole brain (F(1,92)=18.51, …

Objective: Adult survivors of childhood brain tumors are at risk for cognitive performance deficits that require the core cognitive skill of working memory. Our goal was to examine the neural mechanisms underlying working memory performance in survivors. Method: We studied the working memory of adult survivors of pediatric posterior fossa brain tumors using a letter n-back paradigm with varying cognitive workload (0-, 1-, 2-, and 3-back) and functional magnetic resonance imaging as well as neuropsychological measures. Results: Survivors of childhood brain tumors evidenced lower working memory performance than demographically-matched healthy controls. Whole-brain analyses revealed significantly greater blood-oxygen level dependent (BOLD) …
