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.

As a general rule, "neurons that fire together wire together." Unlike the tonotopic map in the auditory cortex, in which the neurons are arranged according to the frequency of sound to which they respond, the neurons in the retinotopic map in the optic tectum are arranged according to the position of the cell bodies of the retinal ganglion cells to which they are connected. The retinotopic map can be inverted, as shown by the classic optic nerve regeneration experiments in frogs.
