This technique of used in human research measures electrical activity of the brain on the scalp.
What is an EEG?
100
These are the receptor cells of the ear.
What are hair cells?
100
Name 2 differences between rods and cones.
Rods: 120 million, found in periphery, light sensitive, low activation threshold, low acuity Cones: 6 million, color sensitive, found in fovea, high activation threshold, high acuity

In what order does visual information pass through the retina?
receptor cells, bipolar cells, ganglion cells
200
Name 2 differences between inner and outer hair cells.
Inner hair cells not attached to tectorial membrane, 1 row, damage is detrimental, synapse with one neuron. Outer hair cells attached to tectorial membrane, 3 rows, synapse with many neurons.
