I have troubles using the terms Cortex & Deep Nuclei, and 'Nuclei' in general. From what I understand, a brain has '3 matter types in accordance to anatomical locations'
- Superficial Grey matter - This is called the 'Cortex (Cerebral or Cerebellar Cortex)'
- Middle White Matter This is called 'Cerebral/Cerebellar White Matter' separating the cortex and deep nuclei
- Deep Grey Matter, deep to the cortex -This is called 'Deep Nuclei' (for e.g.: Basal Nuclei of the Cerebrum, and four deep Cerebellar Nuclei (dentate, globose, emboliform, and fastigial))
Quote from the book that helps me to jump into this conclusion or summary:
'The brain, like the spinal cord, is composed of gray and white matter. Gray matter - the seat of the neurosomas, dendrites, and synapses - forms a surface layer called the CORTEX over the cerebrum & cerebellum, and deeper masses called NUCLEI surrounded by white matter...
