Soma = 10 um, but axon length = 1 m (1,000,000 um). Ratio = 1:100000
Neuron is the basic unit of the neural system
Somatosensory cortex and Neural plasticity
Different species rely on different parts of the body for
adaptive somatosensory information
The area of representation of the hand in the
somatosensory cortex changes after surgical correction
of syndactyly of digits 2-5
Phantom limb sensations can be evoked by stimulating body surfaces
EEG and brain imaging
blood oxygenation level dependent
Higher cognition and Executive brain
Wernicke’s area
Auditory cortex
Visual cortex
Broca’s area
Higher cognition (such as language and speech)
requires many brain area work together
Prefrontal cortex is brain’s CEO

Decision making, Neuroeconomics,
and Neuromarketing
Neuromarketing applications of functional MRI (fMRI) can
potentially enter into the product development cycle
