COGS 100: Exploring the mind
Tiana Chan - Nov 2012
1. Basic anatomy of the neuron.
Dendrite: Receive inputs and carry them to the cell soma.
Soma: Main body of the cell and it contains the nucleus.
Nucleus: Processes and transmits info through electrical and chemical signals.
Axon: Carries the signal to the target.
Myelin sheets: Extension of glial cells. Composed of fatty substance that wraps around
the axon of a neuron.
Nodes of Ranvier: Gaps formed between the myelin sheaths.
Neuron: Cell that processes and transmits info through electrical and chemical signals. A
chemical signal occurs via synapse. Neurons connect to each other to form neural
networks.
1. Gross anatomy of the brain
*Lobes – FPOT
*Supporting lobes - CPMSC
1. Lobes – Each lobe has a different set of functions
The brain: Made of 100 billion nerves that synapses with trillions of connections.
Frontal lobe: attains maturity ~25y.
Parietal lobe:
Occipital lobe:
smallest of the four
lobes
Temporal lobe: two
temporal lobes –
