Animals were exposed to a single blast (0鈥 30 pounds per square inch (psi)) through the ear canal, and brain injury was evaluated by histological and behavioral outcomes at multiple time-points. Blast exposure not only caused tympanic membrane perforation but also produced substantial neuropathol...
7.To figure out how the brain coordinates the two systems, Groh and her co-authors placed small microphones in the ear canal. 8.The researchers conducted a hearing loss test that involves placing electrodes in the participants’ ear canals and on their scalps to measure activity in the inner...

Brain-computer interfaces (BCIs) have attracted considerable attention in motor and language rehabilitation. Most devices use cap-based non-invasive, headband-based commercial products or microneedle-based invasive approaches, which are constrained for i
Owing to the proximity of the ear canal to the central nervous system, in-ear electrophysiological systems can be used to unobtrusively monitor brain states. Here, by taking advantage of the ear’s exocrine sweat glands, we describe an in-ear integrated array of electrochemical and electrophysiolog...
An air gap is formed between the cover and the post. The cover further includes a flexible rubbery material that adjusts shape to match a shape of the ear canal and seal the ear canal. An inner spring holds the cap in the ear canal. The inner spring has a plurality of spring leafs ...
Design and overview of SpiralE Since each person’s auditory meatus has a different shape and size and the internal structure is tortuous, we introduce our SpiralE in a compressed temporary shape (a smaller spiral form) into the ear canal (upper-left inset of Fig. 1a). Then we trigger the...
The auditory or eustachian tube [8] is a canal leading from the middle ear to the pharynx. It normally is closed but opens on swallowing. In an efficient way, this tube can prevent damage to the eardrum and shock to the middle an...
