This paper is a concentrated summary of the interesting findings which Goldstein and Steinfeld published in 1927 as Ein Beitrag zur Analyse der Sexualfunktion in the Zeitschrift für gesamte Neurologie und Psychiatrie.

It concerns the disturbances of the sexual function in a patient with a severe brain injury which had made the visual perception of Gestalten impossible. He was able among other things to compensate the lack of optical images by his kinesthetic memory. The lack of optical images made it impossible for him to create the introductory stages of sexual excitement. He had to be passively 'seduced' until he could utilize kinesthetic functions with which the continuation of the sexual act then became possible. For the orgasm itself, kinesthetic functions seem to be much more important than visual ones.
