A comprehensive reader on the problem of the self as seen from the viewpoints of philosophy, developmental psychology, robotics, cognitive neuroscience,...

The eye may be window to the soul, but neuroscientists aim to get inside and measure the interior directly. There's also talk about moving some walls.

Emotion is normally regulated in the human brain by a complex circuit consisting of the orbital frontal cortex, amygdala, anterior cingulate cortex, and several other interconnected regions. There are both genetic and environmental contributions to the structure and function of this circuitry. We posit that impulsive aggression and violence arise as a consequence of faulty emotion regulation. Indeed, the prefrontal cortex receives a major serotonergic projection, which is dysfunctional in individuals who show impulsive violence. Individuals vulnerable to faulty regulation of (...) negative emotion are at risk for violence and aggression. Research on the neural circuitry of emotion regulation suggests new avenues of intervention for such at-risk populations. (shrink)

The diagnosis of psychopathy is controversial largely because of two notions: first, that because of their defects, psychopaths cannot understand morality, and second, that these defects should thus excuse psychopaths from moral responsibility for their actions. However, it is not clear just what is involved in understanding morality. The argument that the psychopath is ignorant of morality in the same way that one might be ignorant of facts is difficult to sustain. However, a closer examination of the psychopath's peculiar deficiencies (...) reveals that the psychopath's understanding of morality might be impaired in other ways. Keywords: disease, ethics, philosophy, psychopathy, psychiatry, responsibility. (shrink)

There is growing public awareness of the ethical issues raised by progress in many areas of neuroscience. This commentary reviews the issues, which are triaged in terms of their novelty and their imminence, with an exploration of the relevant ethical principles in each case.
