3D modelling technique
visually represents neural tracts
uses MRI techniques

axon hillock
part of the cell body that connects to the axon
telodendria
the branches that axons divide into
axon terminals containing synaptic vesicles at the end of each telondron
synaptic number and strength underlies
processing of sensory information
motor circuits
memory formation
loss of synapses leads to
dementia
paralysis
types of glia
oligodendrocytes
astrocytes
microglia
ependymal cells
synaptic pruning
process of synaptic elimination
occurs during development
phrenology
feeling lumps on patients brain to work out personality and character
false hypothesis
rhombomere
segment of developing neural tube
notochord
flexible rod
helps form midline structure and organisation in neural tube development
essential for patterning of tissues
what secretes Shh
motor chord and floor plate
topographic maps
represent motor and sensory regions
retinotectal pathway
orients eye towards stimulus
visualisation of this can be seen in the zebrafish
analysis of axon guidance
commissure formation
highly organised by expression of transcription factors think ladder (robo/slit)
commissure
band of nerve tissue connecting the hemispheres of the brain, the two sides of the spinal cord, etc.
differential interference contrast (DIC) microscopy
enhances contrast in unstained transparent sampes
total internal reflection fluorescence microscopy (TIRFM)
observes thin region of specimen
advantages of zebrafish as model organism
small cheap easy to maintain grow quickly hundredes of offspring similar genetic structure to humans
