===Neuronal Formation===

Within the brain and the spinal cord the fundamental organisation of the neurons is into 'columns' or groupings of cells within both the sensory and motor regions of the brain and within the grey matter of the spinal cord. Groups of neurons with similar functions are able to form 'nuclei'. Cranial nerve nuclei can include both motor and sensory neurons and are able to undertake a wide variety of functions and tasks. [[Cranial Nerves - Anatomy & Physiology|Cranial nerves]] can also convey fibres from multiple cranial nerve nuclei. Within the spinal cord specific columns of neurones, or [[Sensory Pathways- Anatomy & Physiology#Pathways|'spinal tracts']] convey specific information to high centres in the brain.
