Which one of the following statements about receptive fields in primary visual cortex (V1) is not true? O Like retinal ganglion cells, V1 neurons' receptive fields may have excitatory and inhibitory regions. O There is a lawful relationship between a V1 neuron's receptive field and its location within V1. Individual V1 neurons may respond most strongly to bars of a particular orientation and in a particular part of the visual field. Within the left hemisphere of V1, all of the neurons' receptive fields are in the right eye.
