Indicate true (T) and false (F) statements below regarding the formation of orderly neural maps in the mammalian brain. Your answer would be a four-letter string composed of letters T and F only, e.g. FFFF.
( ) As a general rule, neurons that fire together avoid each other.
( ) In the tonotopic map of the auditory system, brain neurons are arranged in the auditory cortex according to the pitch of the sound they respond to, like the keys of a piano.
( ) In the optic tectum in the midbrain, brain neurons are arranged along the anterior-posterior axis according to the frequency of light they respond to, like the colors of a rainbow.
( ) If the optic nerve of a frog is cut and the eye is rotated 180° in its socket, the retinal ganglion cells reconnect to their original targets in the optic tectum, therefore creating an inverted map.
