      The OCT angular sign of Henle fiber layer (HFL) hyperreflectivity (ASHH) and the pathoanatomy of the HFL in macular disease
      The Henle fiber layer (HFL) is comprised of bundles of unmyelinated photoreceptor axons intermingled with outer Mller cell processes. The photoreceptor axons extend from the cell bodies located in the outer nuclear layer and radially project toward the outer plexiform layer, the inner third of which includes the synaptic junctional complexes and the outer two-thirds of which includes the HFL. The oblique path of the HFL provides unique structural and ...

    3. Overturning the mechanisms of cochlear amplification via area deformations of the organ of Corti

      Overturning the mechanisms of cochlear amplification via area deformations of the organ of Corti
      The mammalian ear embeds a cellular amplifier that boosts sound-induced hydromechanical waves as they propagate along the cochlea. The operation of this amplifier is not fully understood and is difficult to disentangle experimentally. In the prevailing view, cochlear waves are amplified by the piezo-electric action of the outer hair cells (OHCs), whose cycle-by-cycle elongations and contractions inject power into the local motion of the basilar membrane (BM). Concomitant deformations of ...

      Insights into the developing fovea revealed by imaging
      Early development of the fovea has been documented by histological studies over the past few decades. However, structural distortion due to sample processing and the paucity of high-quality post-mortem tissue has limited the effectiveness of this approach. With the continuous progress in high-resolution non-invasive imaging technology, most notably optical coherence tomography (OCT) and OCT angiography (OCT-A), in vivo visualization of the developing retina has become possible. Combining the information from ...

      Current and Future Advanced Imaging Modalities for the Diagnosis of Early Osteoarthritis of the Hip
      Hip osteoarthritis (OA) can be idiopathic or develop secondary to structural joint abnormalities of the hip joint (alteration of normal anatomy) and/or due to a systemic condition with joint involvement. Early osteoarthritic changes to the hip can be completely asymptomatic or may cause the development hip symptomatology without evidence of OA on radiographs. Delaying the progression of hip OA is critical due to the significant impact of this condition ...

      Interplay between traveling wave propagation and amplification at the apex of the mouse cochlea
      Sounds entering the mammalian ear produce waves that travel from the base to the apex of the cochlea. An electro-mechanical active process amplifies traveling wave motions and enables sound processing over a broad range of frequencies and intensities. The cochlear amplifier requires combining the global traveling wave with the local cellular processes that change along the length of the cochlea given the gradual changes in hair cell and supporting cell ...

  4. About UCLA

    UCLA

    University of California at Los Angeles (UCLA) is a public research university located in Westwood, Los Angeles, California, United States. It was founded in 1919, making it the second-oldest general-purpose campus in the University of California system. The name was changed in 1927 to the University of California at Los Angeles. UCLA comprises the College of Letters and Science (the primary undergraduate college) as well as undergraduate colleges Arts and Architecture, Herb Alpert School of Music, Henry Samueli School of Engineering and Applied Science, Nursing, and Theater, Film, and Television, seven professional schools, and five professional Health Science schools. Since 2001, UCLA has enrolled over 33,000 total students annually, and that number is steadily rising.
