Advancing Multimodal Approaches to Study Human Brain: Improvements in Simultaneous EEG-fMRI Acquisition
(2019-12)The primary aim of the study detailed in this dissertation was improving the quality of simultaneous electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) experiments. Two common challenges to use ... -
THE ALAN SHEPARD (SHEP) GENE REGULATES NEURONAL REMODELING DURING METAMORPHOSIS
(2014)Peptidergic neurons are a group of neuronal cells that synthesize and secrete peptides to regulate a variety of biological processes. To identify genes controlling the development and function of peptidergic neurons, our ... -
Amplitude-frequency tradeoffs in the active sensory and communication signal of a weakly electric fish
(2017-06)Animal communication signals play an important role in behavioral processes to ensure fitness and survivorship of individuals within a species. Weakly electric fish produce communication signals that could be among the ... -
THE CENTRAL PATTERN GENERATORS FOR SWIMMING AND SCRATCHING ARE PARTLY SHARED OR INTERACT AT THE INTERNEURONAL LEVEL IN ADULT TURTLES.
(2014-12)Distinct rhythmic behaviors involving a common set of motoneurons and muscles can be generated by separate central nervous system networks, a single network, or partly overlapping networks in invertebrates. Less is known ... -
The Effect of Iron Fortification of Lentils on Blood and Cognitive Status among Adolescent Girls in Bangladesh
(2022-08)Iron deficiency is the world’s most common nutrient deficiency according to the World Health Organization. Iron deficiency is especially prevalent in undeveloped countries and rural areas. A double-blind, cluster-randomized ... -
Elevated Spontaneous Blink Rate in Fragile X Syndrome Implicates Abnormal Dopaminergic Activity in FXS Pathophysiology
(2019-12-13)Fragile X Syndrome (FXS) is the most common, single-gene cause of heritable Autism Spectrum Disorder (ASD) and intellectual disability (ID). FXS is characterized by sensory hypersensitivity, repetitive behaviors, anxiety, ... -
Endogenous opioid modulation of the neural and behavioral correlates of learning and memory necessary for infant attachment.
(2004)Disorganized attachment in which a child attaches to an abusive caregiver is a significant risk factor for childhood and adult psychiatric disorders. Both animal and clinical studies suggest that disorganized attachment ... -
AN EXAMINATION OF NON-LOCAL MUSCLE FATIGUE IN UPPER AND LOWER LIMBS
(2016-05-13)Non-local muscle fatigue (NLMF) is a phenomenon that has been described and examined extensively in literature. Traditionally, interventions have been applied in the unilateral limb to examine the potential short-term ... -
Insulin signaling regulates neurite growth during metamorphic neuronal remodeling
(2014-01-15)Although the growth capacity of mature neurons is often limited, some neurons can shift through largely unknown mechanisms from stable maintenance growth to dynamic, organizational growth (e.g. to repair injury, or during ... -
Investigation into the in vivo metabolism of glutathionyl conjugates of dopamine and norepinephrine: Possible insights into neurodegenerative diseases.
(1997)The in vitro and in vivo hydrolyses of 5-S-Glu-NE were investigated in rat brain homogenates and by intracerebroventricular (icv) administration in rat brains. Under in vitro conditions, 5-S-Glu-NE was hydrolyzed to give ... -
Investigations into the neurodegenerative mode of action of dihydroxytetrahydroquinoline derivatives.
(1997)Preliminary testing of a dihydroxyguinoline derivative, 3-amino-6,7-dihydroxy-1,2,3,4-tetrahydroquinoline (6,7-ADTQ), showed substantial serotonergic depletion in mouse whole brain, but with only moderate selectivity. This ... -
Laboratory and model prediction of rutting in asphalt concrete.
(2003)Rutting is one of the major distresses of flexible pavement. It is defined as the formation of longitudinal depressions under the wheel paths caused by the progressive movement of materials under traffic loading in the ... -
Neurochemical and immunohistochemical effects induced by the 1-methyl-4-phenylpyridinium animal model of Parkinson's disease: An in vivo microdialysis investigation in freely moving rats.
(2003)Parkinson's disease (PD) is a neurodegenerative disorder which afflicts more than 1 million Americans with an estimated 50,000 new diagnoses each year. 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) causes parkinsonian ... -
Neurophysiological mechanisms underlying the distinction between automatic and controlled processes.
(1999)Automatic processes are fast, effortless, mostly unconscious, take very little capacity and are slowly changing. Controlled processes are much slower, require effort and attention, require capacity, are closely tied to ... -
The novelty response of pulse-type weakly electric fish :
(1985)A series of experiments was performed to investigate various behavioral and neurophysiological aspects of the Novelty Response (NR) of pulse-type weakly electric fish. The NR is a reflexive behavior in which the fish ... -
Olfactory bulb coding and odor discrimination.
(2005)Olfactory system second-order neurons, mitral-tufted cells, have odorant receptive fields (ORFs) (molecular receptive ranges in odorant space for carbon chain length in organic odorant molecules). This study quantified ... -
Ontogeny of fear: Influence of corticosterone.
(2005)A strong attachment to the caregiver is critical for survival in altricial species, including humans. While some behavioral aspects of attachment have been characterized, its neurobiology has only recently received attention. ... -
The Pattern Electroretinogram as an Indirect Measure of Dopaminergic Status in Iron Deficiency
(2023-08-04)Animal studies have suggested that iron deficiency negatively affects dopamine (DA) synthesis and reuptake, which in turn negatively affects memory and cognition. However, the literature on the possible relationships among ... -
Synaptic depression and its relation to behavioral habituation within anterior piriform cortex.
(2004)The onset, time course, and extent of LOT synaptic depression during both in vitro electrical and in vivo odorant stimulation methods were similar. Similar to the odor specificity of cortical odor adaptation in vivo, there ...
