The primary conduit between brain and body, carrying motor commands down and sensory information up through organized tracts.
White Matter Tracts
Protection & Support
Membranes, fluid systems, and vasculature that protect and nourish the CNS.
CSF-producing cavities within the brain
Three protective membrane layers
Arterial and venous blood supply
Microscopic Level
Electrically excitable cells transmitting signals through chemical and electrical mechanisms.
Primary excitatory cortical neurons
Large GABAergic cerebellar neurons
Local circuit modulators
Non-neuronal support cells providing structure, metabolism, and immune defense.
BBB regulation, synapse support
CNS myelinating cells
Resident immune cells
Functional Networks
Fine touch, vibration, proprioception to somatosensory cortex.
Pain and temperature to thalamus and cortex.
