1. The Eye

2. The Neuron Major parts of a neuron: Cell body Axon Terminal
Synaptic cleft
Dendrites

3. Projection from the Retina

4. Retinal Ganglion Cells
Retinal Ganglion cells have receptive fields that exhibit a
center-surround structure.

5. Major Cell Types in Retina
Photoreceptors
Bipolar Cells
Horizontal Cells
Amacrine Cells
Retinal Ganglion Cells

6. Periodic Functions Periodic functions repeat with a given frequency:
f(x) = Asin(2pwx)
Amplitude
x (deg)
period
Frequency = number of cycles per unit distance (deg or cm)
Frequency = 1/period = w

7. Fourier decomposition
Any real signal can be
written as a sum of sine
And cosine functions
of different frequencies
and amplitudes
f(x) = 4/p(sin(f) + 1/3sin(3f) + 1/5sin(5f) + ...
