OBJECTIVE Social cognitive disabilities are a common feature in schizophrenia. Given the role of glutamatergic neurotransmission in schizophrenia-related cognitive impairments, we investigated the effects of the glutamatergic NMDA receptor antagonist ketamine on facial emotion recognition. METHODS Eighteen healthy male subjects were tested on two occasions, one without medication and one after administration with subanesthetic doses of intravenous ketamine. Emotion recognition was examined… 
General and emotion-specific neural effects of ketamine during emotional memory formation
The present findings suggest that ketamine produces general as well as valence‐specific effects during emotional memory formation, which partly overlaps with alterations previously observed in patients with schizophrenia.
Neural activities during affective processing in people with Alzheimer's disease
Findings of this study indicate that neural changes in regions associated with the motor and emotional simulation systems might play an important role in the development of Alzheimer's disease.
Facial Affect Recognition and Social Functioning in Individuals at Risk for Schizophrenia Spectrum Disorders
Facial Affect Recognition and Social Functioning in Individuals at Risk for Schizophrenia Spectrum Disorders by Marta Statucka Advisor: Deborah J. Walder, Ph.D. Facial affect recognition (FAR) is
Prenatal exposure to ketamine in rats: Implications on animal models of schizophrenia
Results showed a disinhibition and hyperactive behavior in pubertal animals exposed to ketamine, followed in adulthood with cognitive impairments, social withdrawal, anxiety, depression, and aggressive-like behaviors, suggesting a robust link between prenatal pharmacologic manipulation of NMDA receptors and schizophrenia.
Potential Mechanisms for the Ketamine-Induced Reduction of P3b Amplitudes
Findings show that P3b amplitudes are consistently diminished by an increased task difficulty, as well as after ketamine administration, which indicates that working memory operations, in particular working memory updating are impaired after ketamines, which is in line with previous behavioral findings.
The Acute and Chronic Effects of Ketamine as Revealed by Noninvasive Brain Imaging
Abstract Ketamine, a noncompetitive N -methyl- d -aspartate receptor antagonist, has been used in the experimental psychosis model for a long time. The recreational use of ketamine-induced acute and
Delayed emergence of behavioral and electrophysiological effects following juvenile ketamine exposure in mice
The hypothesis that juvenile exposure to ketamine produces long-lasting changes in brain function that are characterized by a failure to progress along normal developmental trajectories is supported.
Substance misuse and social cognition on the psychosis-spectrum: A bottom-up framework
Abstract The relationship between substance misuse and psychosis is markedly complex, with negative impacts of substance use on physical health, behavior, psychiatric symptoms, and brain function.
Chapter 12 – Ketamine
The pathological changes in the different organs of animal models and humans of ketamine, including its toxicity on central nervous system (CNS), urogenital system, intestine, pancreas, adrenal gland, liver, heart and immune system are summarized.


Impairment in the specificity of emotion processing in schizophrenia.
Differential impairment was seen in patients with schizophrenia for processing emotional faces, although the nonemotional task proved harder for both groups, and emotion discrimination tests could augment the neurobehavioral evaluation of patients.
Impairments of facial emotion recognition and theory of mind in methamphetamine abusers
Impairments in cognitive flexibility are correlated with impairments in facial emotion recognition and ToM within MA abusers, lending further support to the assertion that the capacity to identify emotions from facial expression and infer mental state of others is impaired in MA abusers.
Emotion recognition in individuals at clinical high-risk for schizophrenia.
A trait deficit and an involvement of the amygdala in the pathology of ultra high-risk states are suggested and specific impairments in emotion recognition may be apparent in people at clinical high- risk for schizophrenia before the full expression of psychotic illness.
Ketamine alters neural processing of facial emotion recognition in healthy men: an fMRI study
It is predicted that ketamine would produce reduced activity in limbic and visual brain regions involved in emotion processing, and increased activity in dorsal regions of the prefrontal cortex and cingulate gyrus, both associated with cognitive processing and, putatively, with emotion regulation.
Emotion recognition deficit in schizophrenia: association with symptomatology and cognition
The findings lend support to the concept that emotion recognition is uniquely associated in schizophrenia with core symptomatology and cognitive domains, as well as with healthy control subjects on computerized tasks of emotion and age recognition.
Facial fear processing and psychotic symptoms in schizophrenia: functional magnetic resonance imaging study
An association between impaired extrastriate visual processing of facial fear and negative symptoms, which may underlie the previously reported difficulties of patients with negative symptoms in the recognition of facialFear is indicated.

Impaired performance in healthy siblings and time stability in patients provides evidence of impairment of facial emotion recognition as an actual phenotype of schizophrenia.
Facial emotion recognition in schizophrenia:When and why does it go awry?
Patients with schizophrenia demonstrate abnormalities in early visual encoding of facial features that precedes the ERP response typically associated with facial affect recognition, which suggests that affect recognition deficits, at least for happy and sad discrimination, are secondary to faulty structural encoding of faces.
Facial emotion recognition in Chinese with schizophrenia at early and chronic stages of illness
Chinese patients with schizophrenia, in both the first-episode and chronic stages, performed significantly worse than their control counterparts on overall facial emotion recognition, with specific impairment in identifying surprise, fear and disgust.

Impaired executive functioning did, however, only partially account for the deficits in social perception and social cognition in schizophrenia, which significantly contributes to the understanding of social behavioral problems in schizophrenia.
