Analytical probes capable of mapping molecular composition at the nanoscale are of critical importance to materials research, biology and medicine. Mass spectral imaging makes it possible to visualize the spatial organization of multiple molecular components at a sample's surface. However, it is challenging for mass spectral imaging to map molecular… (More)

Neurophysiological effects of different metal derivatives of atranes at single and repeated introduction into rats have been studied. Spontaneous activity of separate hypothalamic neurons was found to change at introduction of atranes. Discharge activity of hypothalamic [correction of pretubercular] cells changed both in phasic and in tonic mode in response… (More)
The unit activity in the hippocampus formation under the effect of pyracetam was found to depend on the latter dose in rabbits. The ligand-receptor interrelationship with pyracetam seems to exist at the level of the hippocampus formation.
