Towards decoding selective attention through cochlear implant electrodes as sensors in subjects with contralateral acoustic hearing

xlomafota13 shared this article with you from Inoreader Towards decoding selective attention through cochlear implant electrodes as sensors in subjects with contralateral acoustic hearing Via cortical auditory J Neural Eng. 2022 Jan 21. doi: 10.1088/1741-2552/ac4de6. Online ahead of print. ABSTRACT OBJECTIVES: Focusing attention on one speaker in a situation with multiple background speakers or noise is referred to as auditory selective attention. Decoding selective attention is an interesting line of research with respect to future brain-guided hearing aids or cochlear implants (CIs) that are designed to adaptively adjust sound processing through cortical feedback loops. This study investigates the feasibility of using the electrodes and backward telemetry of a CI to record electroencephalography (EEG). APPROACH: The study population included 6 normal-hearing (NH) listeners and 5 CI users with contralateral acoustic hearing. Cortical auditory evoked potentials (CAEP) and selective attention were recorded using a state-of-the-art high-density scalp EEG and, in the case of CI users, also using two CI electrodes as sensors in combination with t he backward telemetry system of these devices (iEEG). MAIN RESULTS: In the selective attention paradigm with multi-channel scalp EEG the mean decoding accuracy across subjects was 94.8 % and 94.6 % for NH listeners and CI users, respectively. With single-channel scalp EEG the accuracy dropped but was above chance level in 8 to 9 out of 11 subjects, depending on the electrode montage. With the single-channel iEEG, the selective attention decoding accuracy could only be analyzed in 2 out of 5 CI users due to a loss of data in the other 3 subjects. In these 2 CI users, the selective attention decoding accuracy was above chance level. SIGNIFICANCE: This study shows that single-channel EEG is suitable for auditory selective attention decoding, even though it reduces the decoding quality compared to a multi-channel approach. CI-based iEEG can be used for the purpose of recording CAEPs and decoding selective attention. However, the study also points out the need for further tec hnical development for the CI backward telemetry regarding long-term recordings and the optimal sensor positions.

Intractable Bleeding Following an Awake Bedside Injection Laryngoplasty in a Patient on KVAD ECMO

xlomafota13 shared this article with you from Inoreader Intractable Bleeding Following an Awake Bedside Injection Laryngoplasty in a Patient on KVAD ECMO Via Journal of Voice Awake injection laryngoplasty (IL) is becoming increasingly utilized in the inpatient setting, especially as a therapeutic option for patients with vocal fold immobility immediately following cardiothoracic surgery. While prior studies consistently demonstrate complication rates below 3%, significant bleeding has not been reported as a major complication in any awake IL case series. The objective of this report is to highlight a case of intractable bleeding following awake inpatient bedside IL in a patient on KVAD (Koji Takeda Ventricular Assist Device) extracorporeal membrane oxygenation (ECMO).
