Great Relief

Guze's famous essay on biological psychiatry – ‘Is there any other kind?’ – argued that humans are biologically evolved creatures, therefore biological processes must contribute importantly to psychiatric disorder. True enough, though perhaps it was inevitable that ‘biological’ psychiatry would be defined in opposition to other kinds of psychiatry like ‘psychosocial’, which would then return to depict it as mindless, blind to context and medically hegemonic. Pluralism is a great relief. Biological processes are always involved, and we can try to utilise them for understanding and treatment if it helps – but we don't have to. Biopsychosocial psychiatry – is there any other kind?

The Right

With the increasing use of neuroimaging research in psychiatry and the role imaging plays in society more generally in how mental illness is understood, it is important to consider the myriad ethical issues raised by imaging technologies, for example, for medicine, for law, and for patients. This chapter provides an overview of major ethical questions concerning: imaging of ethical reasoning in psychiatric disorder; forensic psychiatry, criminality, and responsibility; mindblindness and empathy in autism; the use of neuroimaging for screening, prediction, and diagnosis; “mind reading” and the right to privacy of thoughts; and the implications of imaging for the ethics and politics of biological psychiatry.

The Impact

A major application of potentiometric dyes has been the multisite optical recording of electrical activity in excitable systems. After being championed by L.B. Cohen and his colleagues for the past 20 years, the impact of this technology is rapidly being felt and is spreading to an increasing number of neuroscience laboratories. A second class of experiments involves using dyes to image membrane potential distributions in single cells by digital imaging microscopy - a major focus of this lab. These studies usually do not require the temporal resolution of multisite optical recording, being primarily focussed on slow cell biological processes, and therefore can achieve much higher spatial resolution. We have developed 2 methods for quantitative imaging of membrane potential. One method uses dual wavelength imaging of membrane-staining dyes and the other uses quantitative 3D imaging of a fluorescent lipophilic cation; the dyes used in each case were synthesized for this purpose in this laboratory.

Multicellular Organisms

Apoptosis is an evolutionarily conserved process used by multicellular organisms to developmentally regulate cell number or to eliminate cells that are potentially detrimental to the organism. The large diversity of regulators of apoptosis in mammalian cells and their numerous interactions complicate the analysis of their individual functions, particularly in development. The remarkable conservation of apoptotic mechanisms across species has allowed the genetic pathways of apoptosis determined in lower species, such as the nematode Caenorhabditis elegans and the fruitfly Drosophila melanogaster, to act as models for understanding the biology of apoptosis in mammalian cells. Though many components of the apoptotic pathway are conserved between species, the use of additional model organisms has revealed several important differences and supports the use of model organisms in deciphering complex biological processes such as apoptosis.

History Of

David Magnusson has been the most articulate spokesperson for a holistic, systems approach to personality. This paper considers three concepts relevant to a dynamic systems approach to personality: dynamics, systems, and levels. Some of the history of a dynamic view is traced, leading to an emphasis on the need for stressing the interplay among goals. Concepts such as multidetermination, equipotentiality, and equifinality are shown to be important aspects of a systems approach. Finally, attention is drawn to the question of levels of description, analysis, and explanation in a theory of personality. The importance of the issue is emphasized in relation to recent advances in our understanding of biological processes. Integrating such advances into a theory of personality while avoiding the danger of reductionism is a challenge for the future.
