Special focus on

b) learning difficulties

Comments and notes
Note that the nervous system consists of two different types of cells:
Neurones (nerve cells) of different appearance and size, with fibres/outgrowths that can contact other cells. 
Glial cells, which are also found in great numbers ...view middle of the document...

Main points
An overview of the brain's structure including certain terminology
Different ways of dividing the brain anatomically
Eight basic principles according to which the brain works, for example that the brain excites and inhibits, that is, it uses both gas and brake  
Special focus on 
a) brain size and human behavior 
b) meningitis and encephalitis 
c) stroke 
d) palsy
Comments and notes
This lesson deals with the brain's structure, terminology, cells and fibres, two different ways to divide the nervous system, ten important principles according to which the different parts work: the functional organisation of the brain. One should be able to account for the eight basic principles with examples.
The 12 pairs of cranial- or brain nerves are slightly special and have a specific status. It is suggested that you learn several of them along with their number, for example the optic nerve = brain nerve no. 2. You don't have to know them all by heart, but it can be nice and classy to know them.

Main points
The cells of the nervous system: neurones and glial cells
The inner structure of cells: the most important parts of a cell
Genes, cells, and behavior: chromosomes and genes, phenotype and genotype, dominant and recessive genes, genetic mutation, and chromosome anomalies.  
Special focus on
a) Programming Behavior 
b) Brain Tumors 
c) Multiple Sclerosis (MS) 
d) Huntington's chorea (disease)
e) Brainbow: Rainbow Neurons
Comments and notes
This lesson deals extensively with the cell, its parts, how it is organised and how it works. Extra important will be how the cell's DNA is decoded and finally forms proteins by transcription of the DNA-code to mRNA and translation of the code at the ribosomes in the cytoplasm, so that a number of amino acids can be linked according to the now translated code and become a protein, which is packed and "crumpled up" before it is ready for use. Use the CD-ROM disc for detailed information as well as genetic information from the website below.
Also read about Huntington's disease (chorea) and about brain tumours and MS. Do not forget to read the Summary.
Test on p. 110 and a video about neurones as well as an overview of genetics. Use the CD-ROM disc! Do not forget to read the Summary.
