Along the boundary between adjacent shades of grey in the Mach bands illusion,<unk>  makes the darker area falsely appear even darker and the lighter area falsely appear even lighter. In neurobiology,<unk>  is the capacity of an excited neuron to reduce the activity of its neighbors.<unk>  disables the spreading of action potentials from excited neurons to neighboring neurons in the<unk>  direction. This creates a contrast in stimulation that allows increased sensory perception. It is also referred to as<unk>  antagonism and occurs primarily in visual processes, but also in tactile, auditory, and even olfactory processing. Cells that utilize<unk>  appear primarily in the cerebral cortex and thalamus and make up<unk>  inhibitory networks (LINs). Artificial<unk>  has been incorporated into artificial sensory systems, such as vision chips, hearing systems, and optical mice. An often under-appreciated point is that although<unk>  is visualised in a spatial sense, it is also thought to exist in what is known as<unk>  across abstract dimensions." This refers to<unk>  between neurons that are not adjacent in a spatial sense, but in terms of modality of stimulus. This phenomenon is thought to aid in colour discrimination.
