Abstract
The bioassay process for the determination of alterations in neuronal connectivity and/or morphology comprises the operations of:—identifying the critical distance corresponding to which a pair of spaced single neuronal cells, subjected to the assay, is still able to form reciprocally interconnecting neuritic extensions, after a predetermined incubation period under conditions which favour the formation of such neuritic extensions, wherein each of said single neuronal cells is adhered to a respective spot of a substance promoting the adhesion of said neuronal cells, said spots being deposited at a distance from one another onto a substrate inhibiting the adhesion of neuronal cells, and—comparing the critical distance identified with the critical distance determined, under the same conditions, for reference cells, wherein a decrease in said critical distance for the neuronal cells subjected to the assay, relative to the critical distance for the reference cells, is indicative of an alteration in the neuronal connectivity and/or morphology.
