d: mental representation
the sense in which properties of the outside world (e.g. colours, objects) are copied/simulated by cognition
d: neural representation
the way in which properties of the outside world manifest themselves in the neural signal (e.g. different spiking rates for different stimuli)

parallel to neuraxis and perpendicular to the ground (like the image for this topic)

What is the scienecy name for the layers of the skull?
meninges
What is the name of the outer most layer of the skull?
dura mater
What are the properties of the dura mater?
Tough, flexible, outermost meninx
What is the name for the middle layer of the skull?
Arachnoid
What are the properties of the arachnoid?
The Arachnoid is like a sheet of cling film that is draped over the brain. It does not dip into the valleys of the brain contour.
What is the name for the inner-most layer of the skull?
pia mater
What are the properties of the pia mater?
Last layer of the meninges, which adheres to the surface of the brain
