Complete absence of functioning cones is known as achromatopsia, this very rare genetic disorder leads to total (full spectrum) color blindness. True or False: What these patients see all the time is similar to what a “normal” vision person sees at night via rods.

When ions move across the cell membrane, an electrochemical potential energy change results. Neurons take advantage of this to pickup sensory information and stimulate skeletal muscle movement, e.g., when you grab your pen to write, your brain uses sensory feedback from your fingers to modulate and refine movement of the skeletal muscles that control them. With that, which type of gated channel is operating most proximately (initially) in this pathway to allow sensory neuronal signaling to the brain?
