Amazonian ethnobotany and the search for new drugs.

Ciba Foundation symposium 1994 R E Schultes

Tropical rain forests offer enormous prospects for the discovery of new drugs for use in Western medicine. The Amazon supports 80,000 species of higher plants and a diverse Indian population. Focusing attention on those plants used as medicines by indigenous peoples is the most efficient way of identifying the plants that contain bioactive compounds. There is an urgent need for more...

Slippage in the unity of consciousness.

Ciba Foundation symposium 1993 A J Marcel

Many psychological studies assume a unity of consciousness. Doubt is cast on this assumption (a) by psychophysical studies in normal subjects and those with blindsight showing the simultaneous dissociation of different modes of report of a sensation, and (b) by clinical studies of anosognosic patients showing dissociations of awareness of their own states. These and other phenomena are...

Ciba Foundation symposium 1993 S Shoemaker

It is widely held that a mental state and the subject's introspective belief about it are always 'distinct existences' and only contingently connected. This suggests that for each sort of mental state there could be a creature that is introspectively 'blind' with respect to states of that sort, meaning that while it is capable of having such states, and of conceiving of itself as having them,...

How does a serial, integrated and very limited stream of consciousness emerge from a nervous system that is mostly unconscious, distributed, parallel and of enormous capacity?

Ciba Foundation symposium 1993 B J Baars

Much of the nervous system can be viewed as a massively parallel, distributed system of highly specialized but unconscious processors. Conscious experience on the other hand is traditionally viewed as a serial stream that integrates different sources of information but is limited to only one internally consistent content at any given moment. Global Workspace theory suggests that conscious...

Schizophrenia: the nature of the psychological disturbance and its possible neurochemcial basis.

Ciba Foundation symposium 1979 T J Crow

The diagnosis of schizophrenia is established principally by the presence of certain psychological symptoms which although subjective can be reliably assessed by standardized interviewing procedures. The most characteristic symptoms (Schneider's first-rank symptoms) fall into three groups: (a) auditory hallucinations of particular types, (b) 'ego-boundary disturbances', including intrusions...
