The authors compared regional cerebral blood flow in the brains of 12 psychiatric patients who completed the act of suicide with groups of healthy and nonsuicidal depressed subjects using statistical parametric mapping. Results were consistent with prior imaging studies on depression and were indicative of impaired impulse control and limbic dysregulation, including significant perfusion deficits in the medial prefrontal and subgenual areas (Brodmann's areas 11, 25) and ventral tegmentum. These results warrant further research.

    • "Neuroimaging studies have revealed reduced glucose metabolism in the prefrontal cortex in depressive patients with high-lethality suicide attempts compared to those with low-lethality attempts (Oquendo et al., 2003). Depression patients who completed suicide, compared with non-suicidal depression patients, had significantly higher regional cerebral blood flow (rCBF) in the right hemisphere (Amen et al., 2009). Consistent with this, Hunter and colleagues reported increased right prefrontal EEG coherence when patients with depression experienced worsening of suicidal ideation and mood symptoms during anti-depressant treatment (Hunter et al., 2010).

    ABSTRACT: Self-harm, such as self-cutting, self-poisoning or jumping from height, regardless of intentions, is common among people with schizophrenia. We wished to investigate brain activations relating to self-harm, in order to test whether these activations could differentiate between schizophrenia patients with self-harm and those without. We used event-related functional MRI with a go/no-go response inhibition paradigm. Fourteen schizophrenia patients with a history of self-harm were compared with 14 schizophrenia patients without a history of self-harm and 17 healthy control participants. In addition, we used standard clinical measures and neuropsychological tests to assess risk factors associated with self-harm. The right dorsolateral prefrontal cortex (DLPFC) and the left posterior cingulate cortex differentiated all three groups; brain activation in these regions being greatest in the control group, and the self-harm patient group being greater than in the non-self-harm patient group. In the self-harm patient group, right DLPFC activity was positively correlated with severity of suicidal thinking. In addition, both patient groups showed less activation in the right orbitofrontal cortex, left ventral anterior cingulate cortex and right thalamus. This is the first study to report right DLPFC activation in association with self-harm and suicidal thinking in patients with schizophrenia. This area could be a target for future neuromodulation studies to treat suicidal thinking and self-harm behaviors in patients with schizophrenia. Copyright © 2015. Published by Elsevier Inc.

    • "The practice has drawn heated criticism from mainstream psychiatry. Although papers on the use of SPECT scans in psychiatry [27-32] have been published and providers claim that the work is “based on hundreds of texts and scientific articles” [33], critics contend that the publications do not support the use of SPECT imaging in psychiatric practice [34]. In support of this contention, critics cite the 2006 Practice Guidelines issued by the American Psychiatric Association [35] which state that: "

    ABSTRACT: Functional neuroimaging is being used in clinical psychiatry today despite the vigorous objections of many in the research community over issues of readiness. To date, a systematic examination of the perspectives of key stakeholders involved in this debate has not yet been attempted. To this fill this gap, we interviewed investigators who conduct functional neuroimaging studies involving adults with mood disorders, schizophrenia, obsessive compulsive disorder, and/or attention deficit hyperactivity disorder, providers who offer clinical neuroimaging services in the open marketplace, and consumers of these services, in order to understand perspectives underlying different views and practices. Semi-structured interviews were conducted over the telephone. Verbal consent was obtained and all interviews were audio recorded. Interviews of investigators and service providers followed the same interview guide. A separate set of questions was developed for consumers. All interviews were transcribed and made software ready. We applied the qualitative methodology of constant comparison to analyze the data, whereby two researchers independently analyzed the results into textual themes. Coding discrepancies were discussed until consensus was achieved. Investigators, service providers, and consumers held many common perspectives about the potential or actual risks and benefits of functional neuroimaging for mental illness. However, we also found striking divergences. Service providers focused on the challenges posed by the persistence of symptoms based diagnostic categories, whereas the limitations of the science in this area was the challenge noted most frequently by investigators. The majority of consumers stated that their expectations were met. Our findings point toward a fundamental tension between academic investigators on the one hand, and commercial service providers and their customers on the other. This scenario poses dangers to the communities directly involved, and to public trust in science and medicine more generally. We conclude with recommendations for work that needs to be done to minimize tensions and maximize the potential of neurotechnology through concerted efforts to respect its limitations while leveraging the strengths, investments, and hopes of each stakeholder group.

    ABSTRACT: A systematic experimental study was aimed at elucidating the conditions for which regular axisymmetric pulsations of the anchoring base of diluted propane and methane jet diffusion flames are observed. These self-excited oscillations result in the periodic streamwise contraction and extension of the flame length. The key experimental parameters governing this type of instability, which was only found near the extinction limit, are identified as the reactant stream Lewis numbers, the oxidizer-to-fuel-stream velocity ratio, and the initial mixture strength. For the diluted propane and methane flames studied, the tendency for pulsations increases with decreasing initial mixture strength, increasing reactant Lewis numbers (effective Lewis number typically >1), and decreasing oxidizer stream velocity (for fixed fuel velocity). Finally, possible connections between these experimental findings and combustion instabilities predicted by recent theoretical analyses are briefly discussed.
