Fernando Alonso. Juan Vargas. Fernando Alonso. An important objective in this investigation is to clarify whether sensorimotor gating deficits are also present in other dopaminergic dysregulated disorders with inhibitory impairments. Attention deficit/hyperactivity disorder (ADHD) is a highly prevalent neuropsychiatric disorder that has its onset in early childhood and is characterized by symptoms of inattention and/or hyperactive Substantial evidence suggests that these disorders of impaired “gating” are all associated with dysfunction within interconnected cortico-striatopallido-thalamic circuitry. It is possible to quantify sensorimotor gating in psychiatric patients, and to study the neurobiology of gating … 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.
Sensorimotor Gating in Schizophrenia The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. 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].

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.

Sensory gating describes neurological processes of filtering out redundant or unnecessary stimuli in the brain from all possible environmental stimuli.
In humans and animals, the integrity of sensorimotor gating mechanisms is …

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.

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. Altogether, a reduced sensorimotor gating as an effect of supraphysiological hormonal status, anxiety disorders, SSRIs, and catecholaminergic genotype, implicate the putative relevance of lower PPI as an objective biological correlate of anxiety proneness in pregnant women. sensorimotor gating deficits in schizophrenia, and speculate on future applications of this model in the development of novel therapeutics for this disorder.
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. The schizophrenia group showed reduction in sensorimotor gating for both PPI-60 (SMD = −0.50, 95% CI = [−0.61, −0.39]) and PPI-120 (SMD = −0.44, 95% CI = [−0.54, −0.33]). 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.

One measure that is often used to evaluate the translational relevance of these models to human neuropsychiatric disease is prepulse inhibition of startle (PPI), an operational measure of sensorimotor gating. Deficient PPI characterizes several neuropsychiatric disorders but has been most extensively studied in schizophrenia.

It is possible to quantify sensorimotor gating in psychiatric patients, and to study the neurobiology of gating … 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 Prepulse inhibition (PPI) is a neurological phenomenon in which a weaker prestimulus (prepulse) inhibits the reaction of an organism to a subsequent strong reflex-eliciting stimulus (pulse), often using the startle reflex.The stimuli are usually acoustic, but tactile stimuli (e.g. via … Sensorimotor gating deficits in bipolar disorder patients with acute psychotic mania.
