Lecture 1- September 12, 2017
Neil M. Fournier, Ph.D
Foundations in Neuroanatomy: The Geography of the Mind
Human Brain Most Complex Structure in the Universe
- (includes genetic code, computer central processing units, molecules)
- Volume of human brain 1300 cm^3 or 1300 cc
- Width of a nerve cell 10 µm or 10 x 10^-6 m
- 100 billion nerve cells (10^11)
o Scientific notation
o 100 = 10^2
o 1000 = 10^3
o 10 = 10^1
- ~10^3-10^4 connections per neuron
o 10^11 x 10^3 = 10^14
- Unique connectivity
- Your brains are pretty identical
o differences are represented in unique differences in connectivity
The Brain Maps Everything in the Universe
- Our receptors are not able to see many electromagnetic fields (ex. infrared ad ultraviolet)
- Of all the information you are experiencing, you are only aware of a small amount of it
Understanding Brain Function
- If you understand the hepatocyte, you understand liver function
- If you understand the nephron, you understand kidney function
- If you understand the neuron, you do not understand brain function (yet)
- Dopamine is released when you see a pleasurable stimulus
Brain and Behaviour Logical Approaches to Learning
1. Phylogeny (brain evolution)
2. Ontogeny (brain development)
3. Function (brain physiology and behaviour)
4. Dysfunction (brain disorders)

Central Nervous System
- Nuclei- Collection of cell bodies
- Tracts- Collections of axons
o Spinothalamic tract
Prefix of the word is where it starts
Suffix of the word is where it ends
Starts at the spinal cord and goes to the thalamus
o Corticothalamic
Starts at the cortex and goes to the thalamus
Peripheral Nervous System
- Ganglia- Collection of cell bodies
- Nerves- Collection of axons
Human Brain
- White Matter
o Contains a lot of cholesterol
o Contains the axons/connections (going to the cortex or leaving the cortex)
o Patients with MS have damages in the white matter of their brain
- Grey Matter
o Contains the cell bodies
o Neurons in the cerebral cortex
o 3-5mm thick
