Definitions:

Centre-surround

A term most often used in neuroscience that describes how certain neurons in the visual system are organized to respond differentially to light in the center of their receptive field compared to the surround area.

Receptive Field

A receptive field is the specific region of sensory space (e.g., visual or auditory) in which a stimulus will modify the firing of a particular neuron.

Inhibitory Synapse

A type of synaptic connection that decreases the likelihood of the receiving neuron firing an action potential.

Excitatory Synapse

A synapse at which an action in the presynaptic neuron increases the probability of an action potential occurring in the postsynaptic cell, typically by releasing neurotransmitters.
