Explanation of rod and cone cells
WebSometimes horizontal cells carry signals from one rod or cone to other photoreceptors and to several bipolar cells. When a rod or cone stimulates a horizontal cell, the horizontal cell inhibits more distant photoreceptors and bipolar cells, creating lateral inhibition. ...

Connection to Bipolar Neuron … WebRods can't tell the difference between colors, but they are super-sensitive, allowing us to see when it's very dark. Cones sense color and they need more light than rods to work well. Cones are most helpful in normal or bright light. The retina has three types of cones.

Cones connected singly to bipolar cells so brain receives nerve impulses from small area. Rods have a lower acuity because they are connected in groups, to bipolar cells. Rods have higher sensitivity because they are connected in groups (summation). This is called convergence. filtration instructionsWebStep-by-step explanation. Our vision is an amazing sense and is made up of two different types of cells in the retina: rods and cones.
