Multidisciplinary team interaction: summary and Action Plan.

Introduction: Multidisciplinary team interaction has become a commonplace phrase in the discussion of disaster response. Theme 6 explored multidisciplinary team interactions and attempted to identify some of the key issues and possible solutions to the seemingly intractable problems inherent in this endeavour.

Methods: Details of the methods used are provided in the introductory paper.

Effective models for medical and health response coordination: summary and action plan.

Introduction: To effectively respond to this relatively new, complex mandate, it is essential to find effective models of coordination to ensure that medical and health services can meet the standards now expected in a disaster situation. This theme explored various models, noting both the strengths that can be built on and the weaknesses that still need to be overcome.

Methods: Details of the methods used are provided in the preceding paper.

Pharmacological analysis of slow potentials recorded in frog olfactory bulb during natural stimulation.

Pharmacological agents (strychnine, picrotoxin, pentobarbital, chloralose, GABA, penicillin, morphine) were used to investigate the nature of the slow potential recorded in the frog olfactory bulb in response to natural stimulation. Three possible hypotheses were tested: 1) The slow potential is neuroglial in nature; 2) it is the analog of the dorsal-root potential of the spinal cord and reflects depolarization of primary afferents arising in the terminals of the olfactory nerve and responsible for presynaptic inhibition in the frog olfactory bulb; 3) the slow potential reflects postsynaptic processes. The results showed great similarity between changes in the slow and dorsal-root potentials of the spinal cord in response to the action of pharmacological agents.

[A pharmacologic analysis of the slow potential arising in response to adequate stimulation of the frog olfactory bulb].

The nature of slow potential recorded in the frog olfactory bulb in response to natural stimulation was studied using application of different pharmacological substances. Three suppositions were checked up: 1) if the slow potential is of neuro-glial nature; 2) whether it reflects the primary afferent depolarization in the terminations of olfactory fibres which is responsible for the presynaptic inhibition in the olfactory bulb (as the dorsal root potential in the spinal cord); 3) if it reflects postsynaptic potentials. The slow potential was found to have many pharmacological properties similar to those of the dorsal root potential in the spinal cord.
