6. We see with our brains
◦ Not with our eyes
There is a neural code for vision
◦ Each neuron responds in a particular way to
features of a visual scene

7. The neural codes are described by
mathematical functions (models)
Our research focuses on motion-detecting
neurons
Here, we present a better model of the
responses of motion-detecting neurons

19. Neurons are connected together in chains
(network)
◦ Neuronal hierarchy
Each neuron’s response is based on its input
neurons, and determines the response of its
output neuron

20. Upstream neurons are more likely to be lowpass temporal
frequency filters and downstream neurons are more likely to
be bandpass temporal frequency filters

33. Unlike other models, the sinc wavelet model
represents the temporal frequency character
along the V1 to MT neuron chain
We conclude that the sinc wavelet is a better
model for describing the receptive fields of
neurons in the motion cortex
The sinc wavelet model will provide insights
into how the brain represents visual
information
