Description:  A paint-filled embryonic day 15.5 mouse inner ear illustrating its complex morphology in the context of the whole head.


Fourth Place

Description: This is a vibratome section of a 21-day rat cochlea from the apical turn of the organ of Corti.  It is stained for acetylated tubulin (magenta), actin (green) and nuclei with DAPI (blue).

Description:  "It's an acrylic painting that I made, inspired by my research in the hearing field. It is titled "Auditory Transduction/Under The Sea" as it depicts sound waves, hair cells and neurons using sea imagery".

Description: The Picture is showing the effect of sound intensity on cortical haemoglobin saturation changes. Higher intensity levels lead to an increased brain activation (green 15dB SPL, blue 40dB SPL, black 65dB SPL, red 90dB SPL). Two activation patterns could be detected: a phasic/early response in the supramarginal and postero-superior temporal gyrus and atonic/late response in the antero-superior temporal gyrus and Broca’s area.

Description: Images are part of ongoing research into the effects of autism on the sound localization pathway of ht auditory brainstem.  The medial nucleus of the trapezoid body (MNTB) is a master source of well-timed inhibition in the auditory brain stem and is involved in our ability to isolate sound sources in noisy environments.  To support the precise timing, afferent axons to MNTB neurons are heavily myelinated, and this myelination decreases with age.  The image shows principal neurons of MNTB (magenta) and axons (cyan), taken with CARS (Coherent Anti-Stokes Raman Spectroscopy) with a 60x objective.

Description:  Screen shot from a movie entry.  A series of images were taken. They are a progressive cross sectional series though a zebrafish neuromast. The zebrafish expresses the red (shown in cyan) protein in mechanosensory hair cells of the lateral line, and a green protein that labels all membranes in the cells of the fish. You can see the long kinocilia, the stair step ladder of the stereocilia close to the apical region of the hair cells, support cells surrounding the hair cells, and skin and muscle cells in the fish.  The zebrafish was alive when this image series was taken using a Zeiss Airyscan SuperResolution microscope.
