Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

open access: yesThe Anatomical Record, EarlyView.
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Recovery of Cochlear and Vestibular Function after Labyrinthine Haemorrhage

open access: yesActa Médica Portuguesa, 2014
Inner ear haemorrhage is a rare disorder with disabling symptoms. Prognosis is generally considered to be poor with essentially no chance of functional recovery. The most common aetiologies are related to blood dyscrasias, anticoagulant therapy or local

Predicting ecology and hearing sensitivities in Parapontoporia—An extinct long‐snouted dolphin

open access: yesThe Anatomical Record, EarlyView.
Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.

Sample-Efficient Learning to Solve a Real-World Labyrinth Game Using Data-Augmented Model-Based Reinforcement Learning [PDF]

open access: yesarXiv, 2023
Motivated by the challenge of achieving rapid learning in physical environments, this paper presents the development and training of a robotic system designed to navigate and solve a labyrinth game using model-based reinforcement learning techniques. The method involves extracting low-dimensional observations from camera images, along with a cropped ...

The Site of Lesion in Hearing Loss: Advances in Otoneuroradiology [PDF]

open access: yes, 2020
The last decade has witnessed significant advances in imaging of the middle and inner ear and the auditory pathways. High resolution computerized tomography (CT) scanners and new magnetic resonance (MR) sequences have been implemented in clinical ...

A CASE OF NECROSIS OF THE MASTOID CELLS AND THE ENTIRE LABYRINTH OF THE OTHER SIDE, WITH PARALYSIS OF THE FACIAL NERVE,: FOLLOWED BY PARTIAL RECOVERY OF HEARING. Read at the Congress of Otology, Brussels, September 10, 1888.

open access: yes, 1888
In most of the cases of purulent disease of the ear extending from the middle ear to the brain, the upper bony wall (roof) of the tympanic cavity is the part usually affected, and by this route the disease is carried direct to the cerebrum or cerebellum;

Labyrinth walks: An elegant chaotic conservative non-Hamiltonian system [PDF]

open access: yesarXiv, 2020
In this paper, we show that "Labyrinth walks", the conservative version of "Labyrinth chaos" and member of the Thomas-R\"ossler class of systems, does not admit an autonomous Hamiltonian as a constant function in time, and as a consequence, does not admit a symplectic structure.
