I know some of you are going to scroll down and think I'm not reading all that! For those of you, I have a small summary paragraph at the end. If you're more a "bring it on kinda person", then read the whole thing. I realise the basal ganglia can be a confusing topic, hence this post, if you come across terms your not familiar with, you can look them up in my neuroanatomy primer post.
The aim of this post is to clarify some basic neuroanatomy terms and to give you a sound foundation. Before we start, a quick bit of housekeeping, I use the British spelling for neurone (also used by Gray's Anatomy, The Anatomical basis of clinical practice) as opposed to the American spelling neuron. Abbreviations used include CNS: central nervous system, PNS: peripheral nervous system, SNS: sympathetic nervous system and PSNS: parasympathetic nervous system.
