Example of how deeper parts of the brains are connected to areas in nardis work;
Look up thalamus in the first spoiler. And here is closer look of thalamus
This is the VA part of thalamus:
It sends out information to supplementary(close to nardis F3/4) and primary motor cortex(C3/4, but these sensors also include primary somatosensory).
It gets input from basal ganglia ( http://en.wikipedia.org/wiki/Basal_ganglia http://en.wikipedia.org/wiki/Anatomical_subdivisions_and_connections_of_the_bas al_ganglia#Outputs_of_the_basal_ganglia_system )
The basal ganglia are associated with a variety of functions, including voluntary motor control, procedural learning relating to routine behaviors or "habits" such as bruxism, eye movements, and cognitive, emotional functions. Currently popular theories implicate the basal ganglia primarily in action selection, that is, the decision of which of several possible behaviors to execute at a given time.Experimental studies show that the basal ganglia exert an inhibitory influence on a number of motor systems, and that a release of this inhibition permits a motor system to become active. The "behavior switching" that takes place within the basal ganglia is influenced by signals from many parts of the brain, including the prefrontal cortex(Nardis Fp1/2)
, which plays a key role in executive functions.
Other outputs from basal ganglia system are superior colliculus(aka optic tectum
) ( http://en.wikipedia.org/wiki/Superior_colliculus ) of tectum ( http://en.wikipedia.org/wiki/Tectum ) and VO part of thalamus(not going more indepth on that, but..)
The superior colliculus is involved in preliminary visual processing and control of eye movements. In non-mammalian vertebrates it serves as the main visual area of the brain, functionally analogous to the visual areas of the cerebral cortex(Nardi sensors:O1 & 2) in mammals.
The inferior colliculus is involved in auditory processing. It receives input from various brain stem nuclei and projects to the medial geniculate nucleus of the thalamus, which relays auditory information to the primary auditory cortex.
Optic tectum(Superior colliculus) is shown here(where the tracts from the two eyes meet):
This way the basal ganglia can control what input O1/2 receive from eyes(eye movement) and does some preprocessing in optic tectum. But also control motor systems through thalamus.
Here is a picture that i draw some time ago as an note:
Basically from body to C3/4 it goes something like this:
is connected to your spine(hopefully everyone knows what spine does
) from other end and on pons the other end. It controls autonomic nervous system(things that happen in your body automatically, like breathing, heart etc. involuntary actions of body) and connects spine to other parts of the body.
Link between medulla and pons is called the raphe system:
(didnt write about all parts of limbic system down to my notes, check wiki for more info about those if you want)
The pons contains nuclei that relay signals from the forebrain to the cerebellum, along with nuclei that deal primarily with sleep, respiration, swallowing, bladder control, hearing, equilibrium, taste, eye movement, facial expressions, facial sensation, and posture.
Within the pons is the pneumotaxic center, a nucleus in the pons that regulates the change from inspiration to expiration
The pons also contains the sleep paralysis center of the brain and also plays a role in generating dreams
This white matter includes tracts that conduct signals from the cerebrum(where nardis sensors are) down to the cerebellum and medulla(descending raphe system), and tracts that carry the sensory signals up into the thalamus.
Here you can see the acoustic nerve( http://en.wikipedia.org/wiki/Vestibulocochlear_nerve ) also, which transmits information to the acoustic areas(temporal lobe/ nardis T6/5, along with ears, so the area gets info from two areas, ears and here)
