Molecular and cellular approaches to extrapolation for risk assessment.

Molecular and cellular approaches to extrapolation for risk assessment.

A workshop, "Molecular and Cellular Approaches to Extrapolation for Risk Assessment," was held in Baltimore, Maryland, USA, 5-6 May 1993. The workshop was hosted by the Johns Hopkins Center for Alternatives to Animal Testing and was sponsored by the American Forest and Paper Association, Washington, DC. Forty representatives of government, industry, and academia met to discuss the opportunity t...

Cellular and molecular approaches to memory storage.

There has been nearly a century of interest in the idea that information is stored in the brain as changes in the efficacy of synaptic connections on neurons that are activated during learning. The discovery and detailed report of the phenomenon generally known as long-term potentiation opened a new chapter in the study of synaptic plasticity in the vertebrate brain, and this form of synaptic p...
