Light intensity is the waves:
Height
Width
Frequency
Short wavelengths looks ❌.
Medium wavelengths look ❌.
Long wavelengths look ❌.
Principle of Univariance: a receptors activity is related to the ❌ of photons it catches, not to the ❌ of photons.
Cone Types: Peak ❌ = red.
Peak ❌ = green.
Peak ❌ = blue.
❌ light is often blurred; few are in the fovea and they are more sparse.
❌: have 3 types of cone, but have a deficiency in one cone type.
❌: lack one cone type entirely.
❌: lack colour vision day & night.
❌: damage to V4 area can cause complete "colour blindness".
Types of Anomalous Trichromats: ❌: red/long cone.
❌: green/medium cone.
❌: blue/short cone.
Types of Dichromats: ❌: red/long cone.
Rod Monocromats have no cones at all.
Cells in the LGN and V1 show antagonistic cone inputs. Red/Green cells are ❌.
Blue/Yellow cells are ❌.
Black/White cells are ❌.
Cells in which area exhibit colour constancy?
V1
V2
V3
LGN
V4
