Almost billfish: convergent longirostry, micro‐dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy

Journal of Anatomy, EarlyView.
A fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.

La dehiscencia del canal semicircular superior como forma de presentación de la vestibulopatía periférica

Medicentro, 2017
Introducción: la dehiscencia del canal semicircular superior es una alteración del oído interno caracterizada por la ausencia parcial de la cobertura ósea de dicho canal. En condiciones normales, el oído interno solamente tiene dos ventanas: la oval y la

Three-dimensional characteristics of nystagmus induced by low frequency in semicircular canals of healthy young people

Frontiers in Neuroscience
ObjectiveThe study aimed to analyze the three-dimensional characteristics of nystagmus induced by different semicircular canal combinations in healthy young people, and to determine the reference range of nystagmus slow phase velocity (SPV) and its ...

Osteology and arthrology of the ankle and tarsometatarsus of anoles (Iguania: Anolidae): not convergent with geckos but divergent from the ancestral iguanian condition

Journal of Anatomy, EarlyView.
Geckos and anoline iguanid lizards are well‐known for their possession of adhesive toepads, which are generally regarded as being convergent structures. We show that the anatomical configuration of the foot in these two lineages differs markedly and that these differences likely relate to the contrasing ways they deploy their adhesive systems and ...

An experimentally informed computational model of neurovestibular adaptation to altered gravity

Experimental Physiology, EarlyView.
Abstract Transitions to altered gravity environments result in acute sensorimotor impairment for astronauts, leading to serious mission and safety risks in the crucial first moments in a new setting. Our understanding of the time course and severity of impairment in the early stages of adaptation remains limited and confounded by unmonitored head ...

Firing properties of muscle spindle afferents in the intrinsic foot muscles and tactile afferents from the sole of the foot during upright stance

Experimental Physiology, EarlyView.
Abstract We review our approach for undertaking microelectrode recordings from the posterior tibial nerve at the ankle, which has allowed us to identify, for the first time, the firing properties of muscle spindle endings in the intrinsic muscles of the foot and of cutaneous mechanoreceptors in the sole during unsupported standing.

Ageing changes the proprioceptive contribution to balance control under different types of mastoid vibration: A cross‐sectional study

Experimental Physiology, EarlyView.
Abstract Ageing‐related sensory deteriorations are significantly associated with poor balance control among older individuals, resulting in a higher risk of falling in a dark environment. In particular, the proprioceptive system plays a critical role in maintaining balance.
