In the field of electroencephalographic (EEG) event-related potentials (ERPs), impairments in mechanisms underlying early information processing such as sensory and sensorimotor gating have been reported in PTSD (Javanbakht et al., Reference Javanbakht2011; Kohl et al., Reference Kohl2013).
Further Igsf21 −/− mice exhibit sensorimotor gating deficits, which has also in patients with neuropsychiatric disorders, particularly schizophrenia 39, 40, 41 .
This is consistent with a 'double dose' of deficit explanation amongst those with both diagnoses, explained at least in part by presence of antisocial personality traits and childhood psychosocial deprivation. Sensorimotor gating, defined as the state-dependent regulation of transmission of sensory information to a motor system, is coming of age. It has been known for decades that sensory information does not have unfettered access to its targets in the central nervous system (CNS), as has the fact that sensorimotor gating often occurs via presynaptic inhibition of the activated sensory neuron(s) . Sensorimotor Gating Deficits in Psychiatric disorders. Studies of PPI as an operational measure of sensorimotor gating were originally intended to test the general theory that failures of inhibitory filtering mechanisms can lead to sensory overload and consequent cognitive fragmentation in schizophrenia (Geyer and Braff, 1987; Braff and Geyer, 1990).
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 attention. Alth Impaired Sensorimotor Gating in Unmedicated Adults with Obsessive–Compulsive Disorder Abstract. Functional and structural imaging studies suggest that obsessive–compulsive disorder (OCD) symptoms arise from INTRODUCTION. Obsessive–Compulsive Disorder (OCD) is a severe, chronic psychiatric Prepulse inhibition (PPI) of startle response is a well-established neurophysiological marker of sensorimotor gating ability in psychiatric patients including those with autism spectrum disorders (ASD). PPI has been utilized as an indicator of the central inhibitory function and is potentially linked to the clinical features of this disease. Prepulse Inhibition (PPI) of startle is an operational measure of the pre-attentive filtering process known as sensorimotor gating. Originally identified in patients with schizophrenia, PPI deficits have been observed in multiple but not all psychiatric disorders.
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 processes in cross-species models.
Sensory gating and sensorimotor gating in psychiatric disorders sharing attention deficits Holstein, Dominique H Abstract: Functional gating is an important function of the brain, preventing it from a sensory overload by filtering out irrelevant stimuli. A deficit in gating is characterized by a general reduction of the ability From the Department of Psychiatry, University of California, San Diego, La Jolla. • Human and animal model studies of sensorimotor gating allow us to understand the functional significance of attentional abnormalities and monoaminergic alterations in patients with schizophrenic disorders. Clinically, schizophrenic patients report oversensitivity to sensory stimulation that theoretically correlates with stimulus overload and leads to cognitive fragmentation.
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.

Sensorimotor Gating in Depressed and Euthymic Patients with Bipolar Disorder: Analysis on Prepulse Inhibition of Acoustic Startle Response Stratified by Gender and State Junko Matsuo, Miho Ota, Shinsuke Hidese, Toshiya Teraishi, Hiroaki Hori, Ikki Ishida, Moeko Hiraishi and Hiroshi Kunugi* 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. Studies of sensorimotor gating allow investigators to comment on the spatial and temporal mapping of neurons, trait and state deficits, and vulnerability factors in the schizophrenic spectrum of disorders. By translating attentional theories into testable hypotheses, the neurobiology of schizophrenic disorders becomes clearer.
Disrupted sensorimotor gating has been found in various neuropsychiatric conditions which are characterized by impaired attention,
Sensorimotor gating was abnormal, as measured by deficits in prepulse inhibition of acoustic and tactile startle. Thus, Dvl1 mutants may provide a model for
The so-called family of psychiatric gating disorders can be seen to be consonant with the broad importance of behavioral inhibition, attention, and information
PPI has been proposed to reflect a measure of sensorimotor gating or fil- tering. Deficits in PPI has been found in schizo- phrenia in various prepulse conditions.
