Document Summary
Plasticity of receptive fields in v1 neurons: the visual system is plastic = its constantly adapting and changing to new things (like a movie sort of, the receptive field depends on stimuli and contextual influences, incorrect assumptions. Can"t study the visual system by using only artificial stimuli. Receptive properties of neuron changes as elements in a scene move. Colour is a property of light; with different wavelengths of light, we perceive different colours: achromatic colours. Lower intensities of mixture wavelengths in equal proportions. Between black and white: chromatic colours. Absorbing everything except orange, hence the orange colours. Its absorbing a lot of the lower wavelengths, and reflecting the higher wavelengths toward us. Depends on wavelength of light that reflects into the eye. Rare for an object to reflect a single wavelength of light. Mixture of wavelengths reflected influence our perception of. Component processing: trichromatic theory: theory of colour vision. Each receptor has a different spectral sensitivity.
