None of the "codes" has been ignored. They combined together would not
allow for this kind of frequency-specific sensing and remembering. =
Timecode:within several minutes, you must admit that an action potential
size and shape would not change for the same neural fibre. But what
different sensing can be achieved in those minutes for different pitches
of sound or colours? Inhibition/excitation: what does it matter how
many neurons are inhibited when at least the same type of neurons,
pyramidal cells, for instance in the cortex are multimodal in sensing? =
The Law of Specific Nerve Energies is wrong. Are you suggesting
different neurons would give rise to different sensations? How can
then pyramidal cells in the visuval cortex "see" and in the auditory
cortex "hear?" =
Sorry, no time to repeat myself. Just a little into what I have been
proving and disproving.
However, you are welcoe to come up with more questions. I'll try to
answer them. But, I hae no time to repeat myself too much: I have dealt
with all such other possibilities in my video and earlier volumes. I
have considered all possible factors and excluded the unsound ones. =
Besides, electromagnetic particles have been proven to enter to
stimulate neurons, be registed as such and able to be re-sensed.
At the time of sensing, it's also remembering. When retained in the
neurons and reactivated, that would be re-sensing--remembering....
Can neuronal inhibition/excitation, time code. . . account for and
accomplish all that? =
