| Photoreceptors | show 🗑
|
||||
| show | highly sensitive to light and allow vision even in dim conditions.
🗑
|
||||
| show | no, which is why vision becomes hazy in dim light.
🗑
|

| limitations of cones | show 🗑
|
||||
| show | Yes, The fovea has only cones, but as the distance from the fovea increases, the number of cones decreases.
🗑
|
||||
| show | Rods and cones connect via synapses to bipolar neurons, which then connect to other neurons called ganglion cells.

| show | explains how people discriminate low-pitched sounds that have a frequency below 1000 Hz.
🗑
|
