2 Dec 2011: Lavender, D., Taraskin, S.N. & Mason, M.J. (2011) Mass distribution and rotational inertia of "microtype" and "freely mobile" middle ear ossicles in rodents. ... We also calculate principal axes for these ossicles and discuss alternative interpretations

18 May 2011: The group 1 moles, which tend to show some above-ground activity, include Neurotrichus, Parascalops and Condylura. ... Group 3 includes only the little-known Asian genera Parascaptor and Scaptochirus, which have hypertrophied ossicles.

8 Mar 2011: Although known to be large and heavy, in this study we addressed the question of whether these ossicles are also more dense than typical bone. ... 3. Using solid-state NMR, we demonstrated that this bone is particularly well mineralized, and micro-CT

8 Mar 2011: Mason, M.J., Lai, F.W.S., Li, J.-G. & Nevo, E. (2010) Middle ear structure and bone conduction in Spalax, Eospalax and Tachyoryctes mole-rats (Rodentia: Spalacidae). ... 3) A fluid-based transmission pathway, whereby mandibular vibration sets the

8 Mar 2011: Low anatomical lever ratios and the loss of middle ear muscles are also commonly observed in subterranean species. ... to subserve a form of seismic sensitivity (see Mason, 2003b, and other papers on my publication list).

8 Mar 2011: Mason, M.J. (2003b) Bone conduction and seismic sensitivity in golden moles (Chrysochloridae). ... A model of bone conduction was developed, based on that of Bárány (1938), and measurements from from golden mole middle ears were applied into it.

8 Mar 2011: insertion of the malleus into the tympanic membrane, as found in cats and humans, is functionally related to a change in the vibratory mode of the malleus and incus. ... However, there are some differences between what Puria & Steele observe in cats and

8 Mar 2011: Dr. Matthew Mason: Further Information. University Physiologist Tel: 44 (0)1223 333829, Fax: 44 (0)1223 333840, E-mail: mjm68@cam.ac.uk. Van Dijk, P., Narins, P.M. & Mason, M.J. (2003) Physiological vulnerability of distortion product otoacoustic

8 Mar 2011: females. Given that there are no obvious differences between the inner ears of male and female bullfrogs which might result in a significant difference in impedance, we conclude that models of

8 Mar 2011: Van Dijk, P., Mason, M.J. & Narins, P.M. (2002) Distortion product otoacoustic emissions in frogs: correlation with middle and inner ear properties. ... We recorded DPOAEs from Rana pipiens and Xenopus laevis, but not from Scaphiopus couchii or Bombina

31 Aug 2011: Mason, M.J., Wang, M. & Narins, P.M. (2009) Structure and function of the middle ear apparatus of the aquatic frog, Xenopus laevis. ... across a range of frequencies, this resembling the relationship between tympanic membrane and footplate movement

8 Mar 2011: with crocodiles and alligators from Museum collections in order to see whether genus can viably be transferred. ... The results were surprising and could revolutionize the terminology of these forceps.

8 Mar 2011: We discuss anatomical adaptations subserving, or potentially subserving, seismic sensitivity, and the relative merits of using the auditory rather than the somatosensory system for this purpose. ... Mason & Narins (2009) contains updated information and

25 Apr 2011: Exp. Physiol. 95, 1026–1032. In that paper, the authors claim that they have identified a sex difference between the amount that men and women sweat when subject to different intensities ... 2max. If the same data are re-analyzed and compared against

8 Mar 2011: Although we had suspected from previous anatomical and behavioural studies that golden moles are sensitive to low-frequency vibrations, this had never been tested on live animals. ... The thumpers were playing vibratory sounds recorded as wind passed

8 Apr 2011: 2011) Mechanics of the frog ear. Hearing Research 273: 46-58. In this paper, we review the structure and function of the frog middle and inner ears, going on to use ... Comparisons are made with similar measurements from the mammalian ear, and functional
