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
