Lateral Inhibition from Dictionary of Biological Psychology

lateral inhibition: A feature of RECEPTIVE FIELD organization in SENSORY NEURONS and in other neural systems whereby signals from a RECEPTOR in one region can be inhibited by those from surrounding regions. This causes the neuron to be strongly activated by contrast difference between nearby regions but only weakly by uniform stimulation, giving an efficient sensory code which emphasizes significant stimuli. Lateral inhibition has been most studied in the eyes of arthropods for example LIMULUS and in mammalian retinal ganglion cells see RETINAL CELL LAYERS but it is also an important feature in AUDITORY PERCEPTION and somatosensation.

  1. The subject is fully clear but why does the text lack clarity? But in general your blog is great.
