memory
the human brain
the hippocampus is required for the acquisition of memory
damage to the hippocampus leads to the loss of formation of new memories
information processing in the brain
information processing in the brain
model:memory is a change in strength of
connections
neuron
axon
synapse
memories exist at synapses
neurotransmittermolecules
synaptic vesicles
working on the human brain is impractical

but where are the proteins?
Aequorea victoria
Aequorin converts calcium binding into blue light
Green fluorescent protein converts blue light into green light
tagging proteins with fluorescent proteins
green fluorescent protein converts blue light (488nm) into green light
synaptotagmin GFP
synaptotagmin-GFP is in the nematode brain but is too crude to determine where the
protein is in cells

the diffraction limit of light
the Abbe limit:
In light microscopy, objects can only be resolved if their distance is at least half the wavelength (diffraction limited).
(Ernst Abbe 1840 – 1905)

the size limit of light is broken
