Psy+261+Week+2



The Neural Network shown above exhibits a step by step pattern of vector values leading to specific outputs. In this human brain this can be shown by the example of the eye.



Receptors in the eyes (rods and cones) send electrical signals down the optic nerve, through the optic chiasm and optic tract, to finally arrive in the visual cortex. the photoreceptors in the eyes are the imput of the neural network shown above. the processing and specific vector firings of the visual cortex are what is hidden in the network above. and for an output the specific firings can trigger a response in the motor cortex to allow the proper reaction (output) to the visual stimuli.
