The present invention relates to a method for generating neuroectoderm cells, the method comprising: culturing pluripotent cells for about 2 to about 6 days, wherein the expression and/or activity of one or more proteins selected from the group consisting of fibroblast growth factor receptor (FGFR), son of sevenless (SOS), growth factor receptor-bound protein 2 (GRB2), rat sarcoma protein (RAS), rat fibrosarcoma (RAF), mitogen-activated protein kinase kinase (MEK) and mitogen-activated protein kinase (MAPK) is inhibited. The present invention further relate to a method for generating neurons, the method comprising the steps for generating neuroectoderm cells in accordance with the invention and culturing the neuroectoderm cells for at least about 2 further days. Furthermore, the present invention also relates to a kit comprising means for inhibiting the expression and/or activity of one or more of the proteins selected from the group consisting of FGFR, SOS, GRB2, RAS, RAF, MEK and MAPK, and/or means inhibiting the nodal/activin/TGFbeta/SMAD2/3 signalling pathway, and/or the BMP/GDF/SMAD1/5/8 signalling pathway and, optionally, pluripotent cells.
