Das „Menschlein“ im Laufe der Zeit – Homunkulus

1950 erschien das erste Buch über ihn. Mit den unproportionierten Körperteilen, den langen Fingern, den dicken Lippen und der großen Zunge hat der Homunkulus – lateinisch für „Menschlein“ – einen bleibenden Eindruck hinterlassen. Bis heute repräsentiert er den Körper des Menschen im Gehirn. Zeit, zu schauen, was sich über die Jahre bei ihm verändert hat.
