Neurodevelopmental Processes In The Prefrontal Cortex Derailed By Chronic Hiv-1 Viral Protein Exposure, Kristen A. Mclaurin, Hailong Li, Rosemarie M. Booze, Charles F. Mactutus

Faculty Publications

Due to the widespread access to, and implementation of, combination antiretroviral therapy, individuals perinatally infected with human immunodeficiency virus type 1 (HIV-1) are living into adolescence and adulthood. Perinatally infected adolescents living with HIV-1 (pALHIV) are plagued by progressive, chronic neurocognitive impairments; the pathophysiological mechanisms underlying these deficits, however, remain understudied. A longitudinal experimental design from postnatal day (PD) 30 to PD 180 was utilized to establish the development of pyramidal neurons, and associated dendritic spines, from layers II-III of the medial prefrontal cortex (mPFC) in HIV-1 transgenic (Tg) and control animals. Three putative neuroinflammatory markers (i.e., IL-1β, IL-6, and …

Intelligence And Creativity In The Space-Time Continuum For Education, Business, And Development, Giovanni Emanuele Corazza, Roni Reiter-Palmon, Ronald A. Beghetto, Todd Lubart

Psychology Faculty Publications

In this paper, we address the relationship between the intelligence and creativity constructs, by providing equal-level definitions and a parsimonious description of context, allowing the identification of situations in which either one or the other construct prevails, as well as situations in which they overlap and collaborate. The description of context is performed by introducing the metaphor of the space-time continuum, crossing the dimensions of conceptual space S and available time span T, each one varying in continuity from extreme tightness to extreme looseness. The usefulness of the space-time continuum is not limited to the pure comparison between intelligence and …

Investigating Developmental Changes In Scalp-To-Cortex Correspondence Using Diffuse Optical Tomography Sensitivity In Infancy, Xiaoxue Fu, John E. Richards

Faculty Publications

Significance: Diffuse optical tomography (DOT) uses near-infrared light spectroscopy (NIRS) to measure changes in cerebral hemoglobin concentration. Anatomical interpretations of NIRS data require accurate descriptions of the cranio-cerebral relations and DOT sensitivity to the underlying cortical structures. Such information is limited for pediatric populations because they undergo rapid head and brain development.

Aim: We aim to investigate age-related differences in scalp-to-cortex distance and mapping between scalp locations and cortical regions of interest (ROIs) among infants (2 weeks to 24 months with narrow age bins), children (4 and 12 years), and adults (20 to 24 years).

Approach: We …

The Developmental Plasticity Of Fruit Fly Vision, John Paul Currea

FIU Electronic Theses and Dissertations

In this dissertation we explore the morphological and neural plasticity underlying vision at different scales—within and between species of Drosophila—to elucidate the role of eye development in the evolution of vision. In chapter 2, we offer a tool to accelerate large-scale research into compound eye morphology, and validate it on the eyes of several insect orders and image media. Then, in chapter 3 we demonstrate the developmental plasticity of eye morphology and neural summation in fruit flies, finding an interesting interplay between the two systems. In chapter 4, we elucidate the role of visual plasticity and neural summation in the …

The Effects Of And Interventions For Trauma On Child And Adolescent Development, Jenna Clark

Senior Honors Theses

Trauma is generally defined as an event that causes a lasting impact on an individual, ranging from a natural disaster or medical trauma to abuse. Traumatic events greatly impact development, especially when experienced during childhood and adolescence. These first eighteen years of a child’s life can be divided into three main stages using Erikson’s psychosocial theory and Piaget’s cognitive development theory as these theories provide comprehensive insight into the development of a child. Because of the differences in traumatic experiences and the age of the child, the effects and manifestations of a trauma’s influence will vary between these three different …
