How the brain processes visual information - Further processing

6 important questions on How the brain processes visual information - Further processing

What does a receptive field of a ganglion cell (and lateral geniculate) look like?

A circular center with and antagonistic doughnut-shaped surround (excitatory or inhibitory central portion and a surrounding ring with the opposite effect)

What are the three categories of primate ganglion cells?

Parvocellular neurons, mangocellular neurons and koniocellular neurons

What is a parvocellular neuron?

Neuron with a small cell body, smaller receptive field, in and near fovea, color sensitive, detailed analysis of stationary objects
  • Higher grades + faster learning
  • Never study anything twice
  • 100% sure, 100% understanding

What is a magnocellular neuron?

Neuron with larger cell body (than parvocellular), larger receptive field (than parvocellular), spread throughout the retina (incl. Periphery), no color sensitivity, sensitive to movement and broad outlines of shape

What is a koniocellular neuron

Neuron with smalll cell body, variable but mostly small receptive field, spread throughout the retina, some are sensitive to color, varies responses

Why are the receptive fields larger als we prgress form bipolar cells to later cells in the visual system?

Each cell's receptive field is made by inputs converging at an earlier level (the sum)

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
