Viral studies on human brain culture retrieved from cold storage

Viral studies on human brain culture retrieved from cold storage.

Tissue cultures established from brain tissues of six patients with various chronic, degenerative diseases did not show evidence of viral agents. Sucrose gradient analysis of radioactively labeled culture fluid from two patients failed to reveal the presence of any incomplete or defective virus. Extracellular fluids from three brain cultures contained a factor able to stimulate deoxyribonucleic...

Homodyne tomography of a single photon retrieved on demand from a cavity-enhanced cold atom memory.

We experimentally demonstrate that a nonclassical state prepared in an atomic memory can be efficiently transferred to a single mode of free-propagating light. By retrieving on demand a single excitation from a cold atomic gas, we realize an efficient source of single photons prepared in a pure, fully controlled quantum state. We characterize this source using two detection methods, one based o...

Principles of human brain organization derived from split-brain studies

Studies of damaged human brains have always intrigued neuroscientists. The rich symptomatology that can result is riveting to all who experience examination of such patients. Yet, one of the concerns of basic scientists is that structure-function correlates are difficult to make in the damaged brain, since the lesions are naturally occurring and usually quite diffuse. In addition to the problem...
