Hippocampus..a further place in processing
"unlike other senses, space is not analyzed by a specialized sensory organ"
Thinking is a very interesting and a very strange form of behavior.

"On the motor output side, different motor actions
similarly require the representation of target location in different
reference frames according to the natural coordinates
of the moving muscles. The surprising finding that several
movement planning areas in the PPC represent space in an
eye-centered coordinate frame independent of the sensory
input and motor output may provide a unifying scheme
for multimodal sensory integration and the development of
high-level movement plans.
In area LIP, it was recently established that cells were
involved in the planning of eye movements, regardless of
whether the eye movements were triggered by a visual or an
auditory stimulus (Grunewald et al., 1999; Linden et al.,
1999; Mazzoni et al., 1996b). In further experiments directly
addressing the question of the underlying reference frame,
it was found that the majority of neurons coded auditory
targets, similar to visual targets, in eye-centered coordinates,
and with many response fields of LIP neurons gainmodulated
by eye position (Stricanne et al., 1996). These
findings suggest that LIP is involved in the sensory integration
of visual and auditory signals and that many LIP
neurons are encoding these signals in eye-centered coordinates."

This means that "the field" -as a perceptual concept and as a motor domain- is integrated by the visual system not only because it is the most generous with information about it but also because other sensations deals the field through the visual mapping.
Another thing is that "The sensorimotor Transformation" is performed at the posterior parietal association cortex recieving its sensory input from the visual system.
These notions assures more the perspective that everyone has his individual Vision that its information is privately to him(the relation to the motor output), in contrast to the Auditory system which is primarily function as an analyzer of a physical property(the air vibrations) and not related primarily to field perception and even the indirect calculations done by it, is feeded to the visual map.

Location cues are not contained in the receptor
cells like on the retina in vision, and hence the location for sounds must be calculated.
The sense of location is therefore different from Auditory sensation than that from Vision sensation, as in the vision one it is inherent in contrast to the Auditory which is calculated.
This adds more to the postulation that multiplicity of vision is from sense of location

"The activity pattern of the neurons matched the location of the sound, the team found. Sounds from above, for example, cause neurons towards the top of the auditory centre to fire, whereas sounds from lower down trigger neurons towards the bottom. "The owls basically have a topographic map of space in their brain," says Bala."

Sensory systems are inputing systems, but with a broader view that allow us to develop from each sensory system (namely the auditory & visual systems) an input/output system we might observe different sides of the story.
The Auditory:
Outputting: will be largely from voice and to a little extent from gestures from hands or whatever.
this input/output acoustical system is very useful in communication as we can easily observe.
This enables one to be effectively affecting the outside(people for example) from the inside(inner thoughts)
The visual:
outputting: how to define a visual output??!

1)People as folk achieves the "more than one vision" by their aggregation togeather.
2)every single vision is more than one type of vision.
3)everyone has his own vision & heart..each uniquely for him & different from other one.

Thats how the Holy quraan says it...for always...
i have no stablized thoughts about it.....yet.
but just letting you know this observation.
1) always "al sam3" before "al absar " & "al 2af2eda"
2) always always "al absar" in the plural form & also "al 2af2eda"
Just remember...it is not an incidence....think about it

CNS : central nervous system,
works in the living in the same way the microprocessors do.
Input==>processing==>output
Input in CNS is the environment "sensation"
output "assumed it is the motor actions of the organism"
processing is what is done to achieve best response to environmental inputs...
Current view is :
sensation "input" & motor functions "output"
Further step in this viewpoint concerning man...
All what concerns man interaction with environment are reflexes..
Even THOUGHTS ,emotions etc. are obligatory output from the environmental input.
Human choice & mind system melts down & smashed against that wall...you have no choice..it is reflexes you have nothing to handle it..even these words are reflexes..even your reading to these words are reflexes.
Worth mentioning that according to that, any choice based principles will collapse with it...including the major one of those .."religion"
----------------------------
The holy Quraan mentions something strange about the input output system (I/O SYS) of human being..:
"والله أخرجكم من بطون امهاتكم لا تعلمون شيئا وجعل لكم السمع والأبصار و الأفئدة لعلكم تشكرون"
means: And Allah got you out of your mother's abdomen knowing nothing, and made for you the audition, the visions & the hearts in order you may thank Him.
"أفلم يسيروا في الأرض فتكون لهم قلوب قلوب يفقهون بها أو اذان يسمعون بها فإنها لا تعمى الأبصار ولكن تعمى القلوب التي قي الصدور"
means:Didn't they walk on earth & so they gain hearts know by it or ears hear by it,..it is not vision blindness they have, but blindness in their hearts that inside chests.
The holy Quraan as shown above..adds something called the heart "seems the mind in our talk" to the I/O system.
wether an input or output..it is not clear now for me..but it is not only..
In the 1st verse..God gives us the tools in order to know after the "null contained minds" we used to have when we were born..,
the tools are two of the input system & the heart(mind)
