Book Description :

Psychiatric disorders are uniquely human. Yet we need animal models to test hypotheses about biological mechanisms. Treatment development relies on model systems to evaluate the efficacy of therapeutics. How can such a profound paradox be resolved? Dr. Sylvie Granon of the Institute Pasteur in Paris has successfully assembled a collection of fifteen review chapters that address multiple aspects of rodent models of neuropsychiatric disorders. Outstanding experts describe paradigms relevant to Alzheimer s disease, mental retardation, schizophrenia, autism, attentional deficit hyperactivity disorder, impulsivity, drug addiction, post-traumatic stress disorder, multiple sclerosis, and sudden infant death syndrome. Traditional lesioning and pharmacological methods are contrasted with newer targeted gene mutation strategies for generating rodent models. Strengths and limitations of transgenic and knockout mouse models are discussed by many of the insightful authors. In Alice in Wonderland, the Cheshire Cat speaks English and tell us We re all mad here. Unfortunately, real animals do not talk, and cannot tell us about their abnormal internal emotional or mental states, if any. It is essential to recognize that researchers will never be able to replicate schizophrenia or autism or depression in a mouse. Many psychiatric dysfunctions appear to originate primarily in the human frontal cerebral cortex, a highly developed structure that dramatically eclipses the modest frontal cortex of rodents. Numbers of synapses and available pathways for making neural connections that permit higher executive functions are enormously greater in humans as compared to other species. Expansion of the human prefrontal cortex is an evolutionary recent phenomenon. There has not been enough time for thorough trouble-shooting and beta-testing of its neural circuitry. No wonder so much can go so wrong. Endophenotypes offer a neat solution to our conundrum. Rather than trying to replicate the full human syndrome, specific components of behavioral symptoms and neuroanatomical abnormalities can be modeled in rodents. While mental illnesses that are primarily caused by incorrect developmental neuroanatomy or aberrant neurotransmitter pharmacology in the prefrontal cortex may be difficult to model in mice, whose prefrontal cortex is minimal, connections between frontal cortex and other brain regions such as thalamus are similar across species. Homologies between rodents and primates in frontal cortex connections and specific behavioral functions have been extensively described by Bryan Kolb. The inability of Alzheimer s patients to store new memories represents a discrete characteristic that can be paralleled in rats and mice, who store new memories using similar neurophysiological mechanisms. Schizophrenic patients display deficits in sensorimotor gating and errors in working memory. Very similar procedures and equipment are available to assay prepulse inhibition and working memory in humans, monkeys, rats, and mice. Neuropharmacological pathways mediating the biological actions of abused drugs are similar in humans and rats. Drug addicts show poor impulse control and poor decision making in tasks that are analogous to some forms of errors in the five choice serial reaction time task for rats and mice. Genetic mutations that produce synaptic dysfunctions or amyloid plaques in the human brain are inserted into the mouse genome to create mouse models of mental retardation, which are then evaluated on learning and memory tasks. Thus, a simpler focus on individual endophenotype components of a human disease permits reasonable analogies to be generated in model organisms. The ideal animal model of a human syndrome is quantitative, readily replicated across laboratories, and incorporates three types of validity. Face validity is the conceptual analogy to a human symptom or endophenotype. Some unusual social behaviors in mice offer a conceptual analogy to the first diagnostic symptom of autism, abnormal reciprocal social interactions. Construct validity employs the same cause or precipitating event in the animal model and the human disease. Inflammatory demyelination presents construct validity for a rodent model of multiple sclerosis. Predictive validity confirms the specific therapeutic response. Treatments that work in the human disease also work in the animal model. For example, antidepressants that are effective in treating post-traumatic stress disorder should effectively reverse the behavioral traits of a rat model of this syndrome. Very few animal models of neuropsychiatric diseases incorporate all three types of validity. The authors contributing to this volume explain the challenges, failures and successes of an impressively wide range of model organisms. As the true causes of mental illnesses are identified, neuroscientists and pharmaceutical researchers will design more targeted model systems with true construct validity to the etiologies of neuropsychiatric syndromes. Behavioral assays will continue to be invented and refined to optimize face validity to the endophenotypes of the human disease. Ultimately these endeavors will result in model organisms with high predictive validity and translational value, to enhance the discovery of effective cures for debilitating major mental illnesses.

Book Description :

Diagnosing neurodegenerative diseases can prove particularly intimidating to clinicians, because many times the diagnosis cannot be critically "confirmed" by a simple test. New imaging modalities have advanced to the point of high resolution, morphological, metabolic and functional analysis. Computed tomography, magnetic resonance, nuclear medicine and molecular imaging have recently emerged as outstanding non-invasive techniques for the study of the neurodegenerative disorders. Imaging in Neurodegenerative Disorders covers all the imaging techniques and new exciting methods like new tracers, biomarker, metabolomic and gene-array profiling, potential for applying such techniques clinically, and offers present and future applications as applied to the neurodegenerative disorders with the most world renowned scientists in these fields. This book is an invaluable resource for researchers, clinicians, and trainees in neuroscience, neurology, psychiatry, and radiology.

From a historical point of view the first studies on the response of the organism to stressful situations in general, and on the psychobiology of stress in particular, are probably those of Cannon and de la Paz, the physiologists who showed in 1911 that the adrenal medulla and the sympathetic system are involved in emergency situations. Cannon noted that the venous blood of cats frightened by barking dogs contained adrenaline, a response of the organism which was prevented by adrenalectomy or by section of the splanchnic nerve innervating the adrenal medulla. Cannon suggested that the adrenal medulla was acting in concert with the sympathetic nervous system, so that both systems were activated during stress. The role of the sympathetic system in response to stressful events was later emphasized by the experiments carried out by Maickel et al. (1967) and by Mason (1968): these authors clearly showed that stressors activate the sympathetic system causing it to release adrenaline and noradrenaline. This line of research may be contrasted with that carried out by Hans Selye, centered on of the adrenal cortex in the stress response. Selye's findings and theories originated the role the so-called hypothalamic - pituitary - adrenal cortex (HPA) model of stress: in short, during stress adrenocorticotropic hormone is released from cells of the anterior pituitary and elicits secretion of glucocorticoids from the adrenal cortex.

This volume covers emerging and intriguing topics related to research into steroids and the nervous system, with a major focus on glucocorticoids, non-classical mechanism of action, regulation of reproduction, steroids and glial cells, behavioural effects and pathological correlations.

Book Description :

The discipline of neuroimmunomodulation is devoted to interactions between the immune nervous systems at all levels and includes observation on brain, pituitary, peripheral nervous system and immune cells. Nitric oxide synthase is contained within neurons in the brain and modifies behavioural and hormonal responses by acting on other neurons and on release of peptides and other transmitters through activation of guanylate cyclase and cyclooxygenase. Increases in this and in expression of proinflammatory cytokines can contribute to damage in patients with multiple sclerosis, Parkinsonism, meningitis, stroke, and Alzheimer's disease.

Book Description :

"The subcortical structures of the brain, such as the striatum and thalamus, are positioned deep within the brain and are heavily implicated in the regulation of mood, reward, and memory function. Further, these structures are heavily connected to the frontal lobes of the brain, which include regions that are implicated in complex cognitive tasks. Despite their importance in daily functioning and implication in neuropsychiatric disorders (such as schizophrenia and geriatric depression) and in movement disorders (such as Parkinson's disease and Huntington's diseases), these regions are under-studied, in part due to the paucity of methods available for accurate visualization and extensive analysis of in vivo magnetic resonance imaging (MRI). Five high-resolution T1-weighted MR atlases and three-dimensional surface representations of the striatum, globus pallidus and thalamus were created to consolidate and improve the workflow of an automated segmentation pipeline, MAGeT-Brain. Application of the atlases as input to MAGeT-Brain was implemented to ultimately enable subject-based automated segmentation of the striatum, globus pallidus and thalamus in subject MRI data for the investigation of the normal and healthy aging process. Chapter 3 describes the creation of the five atlases of the striatum, globus pallidus and thalamus, and details the atlas-to-template warping technique used to warp a three-dimensional atlas derived from expertly annotated serial histological sections to five high-resolution MR templates, for their implementation to the MAGeT-Brain pipeline. Registration quality and segmentation accuracy of the atlases were assessed using the Dice's Kappa metric before their implementation to the MAGeT-Brain pipeline.In the context of healthy aging, volumetric analysis of subcortical structures, such as the striatum, globus pallidus and thalamus, has been the sole primary focus of MR-based aging studies. With the improved methodology of the MAGeT-Brain segmentation pipeline, this thesis sought to investigate the normative age relationships of the striatum, globus pallidus and thalamus occurring throughout the healthy adult lifespan; examining various morphological and microstructural features beyond volumetry, which despite being extensively studied is still not yet resolved. Chapter 4 details the age relationships of volume, local surface area, and myelin in the striatum, globus pallidus and thalamus observed across the adult lifespan in healthy individuals between the ages of 18 and 80 using structural T1-weighted and T2-weighted MRI data.Expanding on the results obtained from previous healthy aging studies, we observed age-related linear volumetric decline in the left and right striatum and globus pallidus, and a quadratic volume-age relationship in the left and right thalamus, with complementary posterior areal contraction in all three structures bilaterally. Moreover, we observed a quadratic inverted U shape relationship between T1w/T2w subcortical myelin and age, with a peak T1w/T2w value occurring in middle age (at around 50 years old). This thesis serves to provide a normative baseline for disorders in which these structures are compromised and implicated. This project will have important implications in future research on healthy aging and neuropsychiatric and neurodegenerative disorders." --
