What can you infer about the responsiveness of two neurons in the visual cortex that lie next to each other in v1?

The right answer is The receptive fields of these cells are also next to each other.

The visual cortex occupies the occipital lobe of the brain and is responsible for processing the visual information.

A synapse is the region of interaction between two nerve cells that allows the passage of a signal. The synapse also includes membranes. Most often, the synapse is between the synaptic button of a presynaptic neuron and the dendrite or cell body of a postsynaptic neuron. The postsynaptic neuron transmits the information in an electrical form.

The synapse allows the passage of information from one neuron to another or from a neuron to an effector cell.
