Human Sensation of Transcranial Electric Stimulation. [PDF]

open access: yes, 2019
Noninvasive transcranial electric stimulation is increasingly being used as an advantageous therapy alternative that may activate deep tissues while avoiding drug side-effects. However, not only is there limited evidence for activation of deep tissues by

The petrotympanic canal (Huguier canal): Evolutionary, anatomical, and medical perspectives

open access: yesThe Anatomical Record, EarlyView.
Abstract The petrotympanic canal, traditionally referred to as Civinini's or Huguier's canal, represents an anatomical passage connecting the middle ear and temporomandibular joint (TMJ). Despite its early description, its structural complexity and functional significance have often been underestimated. In this study, we combined historical, anatomical,

The spatiotemporal pattern of the human electroencephalogram at sleep onset after a period of prolonged wakefulness [PDF]

open access: yes, 2019
During the sleep onset (SO) process, the human electroencephalogram (EEG) is characterized by an orchestrated pattern of spatiotemporal changes. Sleep deprivation (SD) strongly affects both wake and sleep EEG, but a description of the topographical EEG ...

Oldest well‐preserved euprimate petrosal, from the early Eocene of India (Vastan Lignite Mine, Gujarat)

open access: yesThe Anatomical Record, EarlyView.
Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

A Retrospective Study to Compare the Surgical Outcomes in Patients Who Underwent Myringoplasty Alone or Along with Cortical Mastoidectomy

open access: yesOnline Journal of Health & Allied Sciences, 2023
Introduction: Chronic suppurative otitis media (CSOM) is a chronic inflammation of the middle ear cleft with non-healing tympanic membrane perforation leading to conductive hearing loss. Surgery is the definitive management. Myringoplasty with or without

Posterior Condylar and Mastoid Emissary Canals, Radiologic Evaluation of Morphological and Morphometric Characteristics

open access: yesVan Tıp Dergisi, 2019
INTRODUCTION: Emissary veins pass through the skull holes and connect the dural venous sinuses and extracranial venous system. Preoperatively, it is crucial to identify the posterior fossa emissary veins because these veins may cause complications during

Event-related brain potential correlates of human auditory sensory memory-trace formation [PDF]

open access: yes, 2005
The event-related potential (ERP) component mismatch negativity (MMN) is a neural marker of human echoic memory. MMN is elicited by deviant sounds embedded in a stream of frequent standards, reflecting the deviation from an inferred memory trace of the ...

Novel application of gamification to support undergraduate anatomy: Student perceptions and performance

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Anatomy is a foundational component of various medical and paramedical disciplines. Existing research has suggested that games or game elements can improve student interest in musculoskeletal (MSK) anatomy. This project builds on previous gamification and serious game work and incorporates new anatomy‐based games into undergraduate anatomy ...

Design, implementation and evaluation of a real-time P300-based brain-computer interface system [PDF]

open access: yes, 2010
We present a new end-to-end brain-computer interface system based on electroencephalography (EEG). Our system exploits the P300 signal in the brain, a positive deflection in event-related potentials, caused by rare events.
