Polychlorinated Biphenyl Exposure Alters Oxytocin Receptor Gene Expression And Maternal Behavior In Rat, Howard Cromwell
Polychlorinated Biphenyl Exposure Alters Oxytocin Receptor Gene Expression And Maternal Behavior In Rat, Howard Cromwell
Howard Casey Cromwell
Polychlorinated biphenyl (PCB) is a persistent organic pollutant known to induce diverse molecular and behavioral alterations. Effects of PCB exposure could be transmitted to future generations via changes in behavior and gene expression. Previous work has shown that PCB-exposure can alter social behavior. The present study extends this work by examining a possible molecular mechanism for these changes. Pregnant rats (Sprague-Dawley) were exposed through diet to a combination of non-coplanar (PCB 47 - 2,20,4,40-tetrachlorobiphenyl) and coplanar (PCB 77 - 3,30,4,40- tetrachlorobiphenyl) congeners. Maternal care behaviors were examined by evaluating the rate and quality of nest building on the last 4 …

Reportinfluence Of Emotional States On Inhibitory Gating: Animal Models To Clinical Neurophysiology, Howard Cromwell
Howard Casey Cromwell
tIntegrating research efforts using a cross-domain approach could redefine traditional constructs used inbehavioral and clinical neuroscience by demonstrating that behavior and mental processes arise not fromfunctional isolation but from integration. Our research group has been examining the interface betweencognitive and emotional processes by studying inhibitory gating. Inhibitory gating can be measured viachanges in behavior or neural signal processing. Sensorimotor gating of the startle response is a well-usedmeasure. To study how emotion and cognition interact during startle modulation in the animal model,we examined ultrasonic vocalization (USV) emissions during acoustic startle and prepulse inhibition. Wefound high rates of USV emission during the …
Controlling Feeding Behavior By Chemical Or Gene-Directed Targeting In The Brain: What’S So Spatial About Our Methods?, Arshad Khan
Arshad M. Khan, Ph.D.
Intracranial chemical injection (ICI) methods have been used to identify the locations in the brain where feeding behavior can be controlled acutely. Scientists conducting ICI studies often document their injection site locations, thereby leaving kernels of valuable location data for others to use to further characterize feeding control circuits. Unfortunately, this rich dataset has not yet been formally contextualized with other published neuroanatomical data. In particular, axonal tracing studies have delineated several neural circuits originating in the same areas where ICI injection feeding-control sites have been documented, but it remains unclear whether these circuits participate in feeding control. However, comparing …
Synaptic And Systems Memory Consolidation In The Black-Capped Chickadee (Poecile Atricapillus), Matthew Barrett
Synaptic And Systems Memory Consolidation In The Black-Capped Chickadee (Poecile Atricapillus), Matthew Barrett
Matthew J. Barrett
ABSTRACT Memory consolidation - the time-dependent stabilization of information- involves two processes: 1) synaptic consolidation and 2) systems consolidation. Synaptic consolidation uses a series of protein synthesis cascades that make lasting changes in the underlying neural architecture of a memory. Systems consolidation involves the reorganization of memory such that, with the passage of time, memory that is initially hippocampus-dependent can be retrieved and activated independent of the hippocampus. Black-capped chickadees (Poecile atricapillus) store and relocate food using hippocampus-dependent spatial memory. In Chapter 2 inhibition of protein synthesis by anisomycin, either 0 and 2 h or 4 and 6 h after …

Prolactin And Fmri Response To Skf38393 In The Baboon, Brad D. Miller, Lauren A. Marks, Jonathan M. Koller, Blake J. Newman, G Larry Bretthorst, Kevin J. Black
Kevin J. Black, MD
Background: This study’s goal was to provide dose-response data for a dopamine agonist in the baboon using standard methods (replicate measurements at each dose, across a range of doses), as a standard against which to subsequently validate a novel pharmacological MRI (phMRI) method. Dependent variables were functional MRI (fMRI) data from brain regions selected a priori, and systemic prolactin release. Necessary first steps included estimating the magnitude and time course of prolactin response to anesthesia alone and to various doses of agonist. These first steps (“time course studies”) were performed with three agonists, and the results were used to select …
Identifying Links In The Chain: The Dynamic Coupling Of Catecholamines, Peptide Synthesis, And Peptide Release In Hypothalamic Neuroendocrine Neurons, Alan Watts, Arshad Khan
Identifying Links In The Chain: The Dynamic Coupling Of Catecholamines, Peptide Synthesis, And Peptide Release In Hypothalamic Neuroendocrine Neurons, Alan Watts, Arshad Khan
Arshad M. Khan, Ph.D.
Compared to conventional neurons that use synaptic mechanisms to communicate with closely apposed targets, peptidergic neuroendocrine neurons release relatively large quantities of peptide into the vasculature to control neuroendocrine function at more distal sites. This means that maintaining adequate amounts of peptide for release through controlled biosynthesis is critical for their function. But the flexible and adaptive responses these neurons generate to many different challenges require synthesis and release must be coordinated in some way. How neuroendocrine—or in fact, any neuropeptide—neurons link appropriate levels of peptide biosynthesis with the patterns of action potentials that drive peptide release is unknown. Here …

This report represents a summary of the discussions led by the antiseizure treatment working group of the International League Against Epilepsy (ILAE)/American Epilepsy Society (AES) Working Groups joint meeting in London (London Meeting). We review here what is currently known about the pharmacologic characteristics of current models of refractory seizures, both for adult and pediatric epilepsy. In addition, we address how the National Institute of Neurological Disorders and Stroke (NINDS)-funded Anticonvulsant Screening Program (ASP) is evolving to incorporate appropriate animal models in the search for molecules that might be sufficiently novel to warrant further pharmacologic development. We also briefly address …

Neural Input Is Critical For Arcuate Hypothalamic Neurons To Mount Intracellular Signaling Responses To Systemic Insulin And Deoxyglucose Challenges In Male Rats: Implications For Communication Within Feeding And Metabolic Control Networks, Arshad Khan, Ellen Walker, Nicole Dominguez, Alan Watts
Arshad M. Khan, Ph.D.
The arcuate nucleus of the hypothalamus (ARH) controls rat feeding behavior, in part, through peptidergic neurons projecting to the hypothalamic paraventricular nucleus (PVH). Hindbrain catecholaminergic (CA) neurons innervate both the PVH and ARH, and ablation of CA afferents to PVH neuroendocrine neurons prevents them from mounting cellular responses to systemic metabolic challenges such as insulin or 2-deoxy-D-glucose (2-DG). Here, we asked whether ablating CA afferents also limits their ARH responses to the same challenges or alters ARH connectivity with the PVH. We examined ARH neurons for three features: (1) CA afferents, visualized by dopamine-β-hydroxylase-immunoreactivity (DBH-ir); (2) activation by systemic metabolic …

Serotonin Transporter (5-Httlpr) Genotype And Childhood Trauma Are Associated With Individual Differences In Decision Making, Scott Stoltenberg
Serotonin Transporter (5-Httlpr) Genotype And Childhood Trauma Are Associated With Individual Differences In Decision Making, Scott Stoltenberg
Scott F. Stoltenberg
The factors that influence individual differences in decision making are not yet fully characterized, but convergent evidence is accumulating that implicates serotonin (5-HT) system function. Therefore, both genes and environments that influence serotonin function are good candidates for association with risky decision making. In the present study we examined associations between common polymorphisms in the serotonin transporter gene (SLC6A4; 5-HTTLPR and rs25531), the experience of childhood trauma and decision making on the Iowa gambling task (IGT) in 391 (64.5% female) healthy Caucasian adults. Homozygosity for the 5-HTTLPR L allele was associated with riskier decision making in the first block of …

Auditory Inhibitory Gating In Medial Prefrontal Cortex: Single Unit And Local Field Potential Analysis, Howard C. Cromwell
Auditory Inhibitory Gating In Medial Prefrontal Cortex: Single Unit And Local Field Potential Analysis, Howard C. Cromwell
Howard Casey Cromwell
Medial prefrontal cortex is a crucial region involved in inhibitory processes. Damage to the medial prefrontal cortex can lead to loss of normal inhibitory control over motor, sensory, emotional and cognitive functions. The goal of the present study was to examine the basic properties of inhibitory gating in this brain region in rats. Inhibitory gating has recently been proposed as a neurophysiological assay for sensory filters in higher brain regions that potentially enable or disable information throughput. This perspective has important clinical relevance due to the findings that gating is dramatically impaired in individuals with emotional and cognitive impairments (i.e. …
