Positron Emission Tomography Imaging Reveals Auditory and Frontal Cortical Regions Involved with Speech Perception and Loudness Adaptation. [PDF]
Considerable progress has been made in the treatment of hearing loss with auditory implants. However, there are still many implanted patients that experience hearing deficiencies, such as limited speech understanding or vanishing perception with ...

Electrically Evoked Auditory Brainstem Responses in Children with Sequential Bilateral Cochlear Implants [PDF]
To examine the effect of sequential bilateral cochlear implantation on auditory brainstem maturation and the effect of age in receiving the second implant (CI2).Prospective cohort study.Tertiary academic referral center.Thirty prelingually deaf children, who received their first implant (CI1) at a mean age of 1.8 year and their CI2 at a mean age of 5.3

Implantation of two electrical stimulators of different cranial nerves in one patient is rare. We report the case of a forty-seven-year-old patient already implanted with a trigeminus nerve stimulator.

Envelope enhancement increases cortical sensitivity to interaural envelope delays with acoustic and electric hearing. [PDF]
Evidence from human psychophysical and animal electrophysiological studies suggests that sensitivity to interaural time delay (ITD) in the modulating envelope of a high-frequency carrier can be enhanced using half-wave rectified stimuli.

Electrical Dipole Magnitudes of Auditory Brainstem Responses.
ABRのI波およびV波について電流双極子のベクトル成分を求め, その臨床的有用性を検討した。 I波・V波とも双極子のベクトルの大きさにはかなり大きな個体差がみられ, 今回用いた方法では臨床応用にはまだ問題があるものと思われた。 I波においては刺激音圧が90から60dBnHLまでは音圧の減少とともに著しくベクトルの大きさが減少したが, 刺激音圧60dBnHL以下ではベクトルの大きさの変化はゆるやかであり, これは蝸電図APのH曲線とL曲線に対応するものとも考えられた。 また刺激音圧を減少させると, I波のベクトルの大きさの減少の方がV波のベクトルの減少より著明で, これは神経パルスの同期性と関連した現象とも推測された。

Midbrain PAG Astrocytes Modulate Mouse Defensive and Panic‐Like Behaviors
Astrocytes in the midbrain periaqueductal gray (PAG) dynamically encode threat intensity and shape defensive action selection in mice. Real‐time Ca2+ imaging reveals robust astrocytic activation during predator odor and CO2 exposure. Aberrant astrocytic Ca2+ overactivation disrupts goal‐directed escape, biases behavior toward freezing, and induces ...

XIAP Stabilizes DDRGK1 to Promote ER‐Phagy and Protects Against Noise‐Induced Hearing Loss
Mechanism of GAS‐mediated protection against noise‐induced hearing loss (NIHL). Noise exposure activates the ATF4/eIF2α axis, downregulating XIAP and promoting DDRGK1 degradation, thereby inhibiting ER‐phagy and leading to hair cell (HC) death. GAS treatment rescues XIAP and DDRGK1 expression, reactivating ER‐phagy to mitigate HC loss, synaptic damage,
