Key points
・ Tilt perception is formed from the vestibular and
somatosensory input.
・ We improved an electric goniometer that enabled digital
display of the tilt angle
for easy analysis of the results to study the tilt perception and short
term memory
of tilt perception.
・ It became clear that the vestibules are less important than
the somatosensory
input.
・ The bilateral group could also successfully remember tilt
positions.
・ It is clear that such information is remembered for at least
a short period of time.
