Snapshots in Neuroscience: Mouse Cochlea
This image has been selected to showcase the art that neuroscience research can create.
As described by Dr. Zhirong Wang and colleagues: This image shows an immunostained whole-mount preparation of a mouse cochlea. Cells localized at the bottom (blue) of the image are spiral ganglion neurons (primary auditory neurons) in the inner ear. Their peripheral axons bundle up (magenta) and extend towards sensory hair cells (not shown in this picture) to pick up sound information then relay it to the brain. There are also nerve fibers coming from the brain to modulate auditory input and they appear green/white in this image which covers the area of the neuronal cell body area.
Proper development of spiral ganglion neurons and precise connection between them and sensory hair cells are critical for hearing. We showed that a type of ATP-gated ion channels is required to maintain the size and complexity of spiral ganglion neuron terminal structures during early development.
This image is taken by a Zeiss laser scanning confocal microscope (LSM 880) through a 20× objective (Plan-Apochromat 20×/0.8 Oil DIC M27) at 1024 by 1024 pixels.
