Schizophrenia is a complex psychiatric disorder exhibiting alterations in spontaneous and
task-related cerebral activity whose relation (termed “state dependence”) remains unclear …

Latent inhibition (attenuated responding to a signal due to signal-alone presentations
preceding the signal-outcome pairings) and blocking (attenuated responding to Signal B …

Prepulse inhibition (PPI) refers to a reduction in the amplitude of the startle eyeblink reflex to
a strong sensory stimulus, the pulse, when it is preceded shortly by a weak stimulus, the …

Paying attention to visual stimuli is typically accompanied by event-related
desynchronizations (ERD) of ongoing alpha (7–14 Hz) activity in visual cortex. The present …

Background One of the most common deficits in patients with schizophrenia (SZ) is in
working memory (WM), which has wide-reaching impacts across cognition. However …

Rationale: Patients with schizophrenia exhibit deficits in an operational measure of
sensorimotor gating: prepulse inhibition (PPI) of startle. Similar deficits in PPI are produced …

Individuals with schizophrenia are known to show deficits in prepulse inhibition (PPI) of the
startle response. PPI refers to a response suppression in reaction to a strong startling …

The startle response is composed by a set of reflex behaviors intended to prepare the
organism to face a potentially relevant stimulus. This response can be modulated by several …

In recent years, schizophrenia research has focused on inhibitory interneuron dysfunction at
the level of neurobiology and on cognitive impairments at the psychological level …

Recent heuristic models of schizophrenia propose that abnormalities in the gamma
frequency cerebral oscillations may be closely tied to the pathophysiology of the disorder …
