Neuropsychiatric disorders such as schizophrenia, Huntington's disease, obsessive-compulsive disorder, attention-deficit disorder, and Tourette's syndrome are associated with deficiencies in sensorimotor gating mechanisms [4]. In humans and animals, the integrity of sensorimotor gating mechanisms is … Depression, Sensorimotor Gating, C3H/HeJ, Prepulse Inhibition, Circadian Rhythm 1. Introduction Sleep disorders are commonly associated with prevalent neuropsychiatric dis-orders such as mood disorders and anxiety disorders [1]. It is speculated that etiological factors responsible for mental disorders are also in conflict with the Background: Prepulse inhibition (PPI) is an operational measure of sensorimotor gating and is impaired in a family of neuropsychiatric disorders characterized by abnormalities of inhibitory function. Adults with autistic disorder (AD) exhibit clinical features of inhibitory deficits, such as restrictive and repetitive behaviors, that may be explained by deficits in sensorimotor gating.

Fundamental gating mechanisms appeared intact, while the pattern of deficits in trauma-affected refugees with PTSD point toward a different form of sensory overload, an overall neural hypersensitivity and disrupted the ability to down-regulate stimuli responses.

The sensitivity and meta-regression analysis showed that sample size, gender proportion, imbalance for gender, source of control group, and study continent were sources of heterogeneity ( P < .05) for both PPI-60 Although elemental sensation is normal in patients with tics, tics can be associated with sensory phenomena. Some neurophysiological studies suggest that an altered “gating” mechanism also underlies the development of tics. This review underlines the importance of abnormal sensorimotor integration in the pathophysiology of movement disorders. Thus, sensorimotor and sensory gating measures can be used as informative and independent neurophysiological markers for studies investigating neuropsychiatric disorders and may well constitute separable endophenotypes. Functional and structural imaging studies suggest that obsessive–compulsive disorder (OCD) symptoms arise from dysfunction in cortico-striato-thalamo-cortical circuits. It has therefore been hypothesized that neurophysiological tasks subserved by these circuits should be abnormal in OCD patients. One neurocognitive probe associated with this circuitry is prepulse inhibition (PPI) of the 2001-08-21 · Pronounced sensorimotor gating abnormalities have been reported in schizophrenic patients (Braff et al.

Sensory gating is an essential feature of the central nervous system reflecting a pre- attentive automatic process, in which responses to irrelevant, repetitive stimuli are filtered, or gated, saving processing resources for perceptually more salient input (Adler et al., Objectives: Few studies have examined acoustic startle sensorimotor gating in bipolar disorder (BPD) despite the fact that patients with BPD have exhibited inhibitory dysfunctions on a variety of Sensorimotor gating in manic and mixed episode bipolar disorder - Carroll - 2007 - Bipolar Disorders - Wiley Online Library Adults with AD have sensorimotor gating deficits similar to other neurodevelopmental disorders, implicating a failure of normal inhibitory regulation of sensory, motor, and attentional mechanisms. as a possible risk indicator for different mental disorders, helping to define a specific endophenotype. Specifically, we examine different experimental procedures to measure impaired response in attention linked to sensorimotor gating as a possible personality trait involved in maladaptive behaviors.

Sensorimotor gating is a normal protective mechanism in the brain that functions to gate or filter irrelevant sensory stimulation, allowing for coherent thought. Deficits in sensorimotor gating may result in stimulus overload and the misinterpretation of sensory information. Sensory gating describes neurological processes of filtering out redundant or unnecessary stimuli in the brain from all possible environmental stimuli. Also referred to as gating or filtering, sensory gating prevents an overload of irrelevant information in the higher cortical centers of the brain. Sensory gating can also occur in different forms through changes in both perception and sensation, affected by various factors such as "arousal, recent stimulus exposure, and selective Citation: Vargas JP, Díaz E, Portavella M and López JC (2016) Animal Models of Maladaptive Traits: Disorders in Sensorimotor Gating and Attentional Quantifiable Responses as Possible Endophenotypes.
