[Modification of visual perception by vision training].

The course of the visual pathway as far as the sulcus temporalis superior is described and the change in the shape of the receptive fields is pointed out. The transformation of action potentials into conscious perception is interpreted as it was by Eccles. A connection is made between the problem of learning and the plasticity of the spine synapses, the capacity of which can be considerably increased. In conclusion, it is pointed out that in cases of macular disease it is possible to stimulate peripheral areas of the visual field by special training and thus to help the visual field by special training and thus to help the patient.
