Taschenbuch. Zustand: Neu. Neuware - In the past forensic psychiatry has been a sub-speciality of general psychiatry without its own, separate identity. However, since the mid-1980s there has been a growing in terest in the application of community care principles to mentally disordered offenders. A new set of attitudes have developed which have enabled the mentally disordered offender to emerge from relative institutional obscurity to a much higher profile in the community. Although numerically small in relation to the general psychiatric population, forensic patients tend to attract the public' s attention by virtue of their greater propensity for troublesome behaviour. Such a group needs expert community support in order to maintain an accepta bie public face. Unfortunately these developments have outstripped the creation of training opportunities for community staff charged with their support and supervision. Most community practi tioners have had to learn 'on the job' with inadequate support and supervision from senior staff, who of ten have less direct experience of working with this client group than themselves. Just such a situation prompted the authors, in 1990, to establish a module on 'Working with Mentally Disordered Offenders in the Community' as part of an MA in Social W ork at the University of Reading. As the course developed it became clear that the topic and content had equal application to other community professionals working in the field.…

Buch. Zustand: Neu. Neuware - How does the brain code and process incoming information, how does it recog nize a certain object, how does a certain Gestalt come into our awareness One of the key issues to conscious realization of an object, of a Gestalt is the attention de voted to the corresponding sensory input which evokes the neural pattern underly ing the Gestalt. This requires that the attention be devoted to one set of objects at a time. However, the attention may be switched quickly between different objects or ongoing input processes. It is to be expected that such mechanisms are reflected in the neural dynamics: Neurons or neuronal assemblies which pertain to one object may fire, possibly in rapid bursts at a time. Such firing bursts may enhance the synaptic strength in the corresponding cell assembly and thereby form the substrate of short-term memory. However, we may well become aware of two different objects at a time. How can we avoid that the firing patterns which may relate to say a certain type of move ment (columns in V5) or to a color (V 4) of one object do not become mixed with those of another object Such a blend may only happen if the presentation times be come very short (below 20-30 ms). One possibility is that neurons pertaining to one cell assembly fire syn chronously. Then different cell assemblies firing at different rates may code different information.…
