  • Discovery of ganglion photoreceptors in the eye
    • Dr Russell Foster
      • Lecture in London, UCL
    • ganglion cells specialized to encode ambient light intensity
      • ganglion communicate directly with the brain
        • synchronize circadian rhythms with the solar day
          • Circadian Rhythms
            • Circadian rhythms are biological cycles that have period of about a day.
              • In mammals, a pacemaker in the hypothalamus called the suprachiasmatic nucleus (SCN) drives these rhythms
                • Light shown to co-ordinate sleep patterns when detected, not by rods/cones but by ganglion. and entrains the SCN and internal body clock.
      • Dr. Van Gelder said. “If you’re blind from an optic nerve disease, you’re nine times more likely to have significant daytime sleepiness than if you are blind from other causes.”

    • Opinions
      • I think this discovery shows our incomplete knowledge of science and ourselves and reminds us that when using science as a truth to prove or disprove womething we need to take care. Eg Determinism.
  • it is interesting to see how our make up can affect our psych9ological moods and behaviour and this shows us there is still undiscovered science.
