The "Groupe International de Recherche sur l'Infinitésimal" (GIRI) was
created in 1986 by Professor Madeleine Bastide and Doctor René Halm.
Madeleine Bastide was its President for several years. The group
comprises actually more than 100 researchers from different disciplines
(physicians, chemists, biologists, pharmacologists, physicists, etc. )
from 22 different countries. The original aim, which, for the most part,
has now been achieved, was to create a working group to exchange ideas
and results concerning the effects of very low doses and high dilutions.
Madeleine Bastide then proposed to publish a collection of the lectures
given at their scientific meetings in a bilingual book (French and
English) entitled "Signals and Images". The first volume was published
in 1990 by the ATELIERS ALPHA BLEUE. It contains lectures on the new
pharmacological approach and related concepts that were presented at the
3rd and 4th Symposiums held in Paris in 1989 and 1990. This volume
treats the problem of the effects of very low doses and high dilution in
in vitro and in vivo experimental models. It is conceivable that this
effect, like that of elect- magnetic fields, is none other than an
"ultra molecular" effect as shown in yet p- lished results. The effect
could be interpreted as a piece of information, i. e. a signal whose
transmission and perception remains to be elucidated. According to
Madeleine Bastide "everything depends on the nature and quality of the
information, signals and images".
