摘要: Abstract The ERG of the embryonic and hatched chick was recorded in response to light pulses varying intensity, wavelength sequence. results were correlated with histology retina, concentration visual pigment, rhodopsin, determined as a function age animal. first consisted two cornea-negative waves (a 1 -anda 2 -waves) which interpreted be cone receptor potential second elements lying post-synaptic receptors. Rhodopsin absent or present very low concentrations at when an could recorded. Positive activity (b 3 -wave) appeared day later than underwent series changes properties within days. Theb-wave separated into sub-waves -andb thought represent photopic scotopic respectively. are related findings other investigators.
