Standard neuropsychological tests are insensitive to important memory deficits experienced by patients, particularly in spatial\u002Fscene memory, recollective experience, and familiarity processing. Using a validated virtual tour paradigm, the study examines how familiarity-based recognition and recall of spatial scenes relate to specific brain structures. In Aim I, a large cohort of patients with varied temporal lobe lesions at Emory University undergoes the virtual tour task with voxel-based lesion-symptom mapping to localize necessary brain regions. In Aim II, scalp event-related potentials and eye tracking in healthy participants at UC Davis characterize the temporal dynamics and lateralization of scene recognition. In Aim III, intracranial EEG recordings (including local field potentials and single-unit activity) in epilepsy surgery patients at UC Davis determine the precise network dynamics underlying spatial scene familiarity and recall. The long-term goal is to improve the prediction and prevention of cognitive morbidity from epilepsy surgery by providing a more complete model of spatial recognition memory circuits.",[28,29,30,31,32,33,34,35,36,37,38,39],"Focal Epilepsy","Temporal Lobe Epilepsy","Medically Refractory Epilepsy","Memory Disorders","Epilepsy Comorbidities","Epilepsy Intractable","Epilepsy Surgery","Epilepsy, Temporal Lobe","Memory Deficits","Memory Disorder, Spatial","Memory Dysfunction","Spatial Perception",[41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64],"spatial memory","recognition memory","familiarity","recollection","neural circuits of memory","phenomenology of memory","scene memory","virtual tour","epilepsy surgery","SEEG","stereo-electroencephalography","lesion-symptom mapping","network-symptom mapping","cognitive electrophysiology","event-related potentials","intracranial EEG","iEEG","parahippocampal gyrus","perirhinal cortex","hippocampus","tetrodes","deja vu","neuropsychology","consciousness","RECRUITING","2026-05-06",{"date":68,"type":69},"2026-05-12","ACTUAL",{"date":71,"type":69},"2024-07-01",{"date":73,"type":22},"2030-06-30",{"name":75,"class":76},"University of California, Davis","OTHER",{"id":78,"slug":79,"hasResults":11,"nctId":80,"briefTitle":81,"officialTitle":82,"acronym":4,"eligibilityCriteria":83,"healthyVolunteers":16,"sex":17,"minAge":18,"maxAge":84,"enrollmentInfo":85,"targetDuration":4,"studyType":23,"phases":87,"briefSummary":88,"conditions":89,"keywords":93,"overallStatus":65,"whyStopped":4,"lastUpdateSubmitDate":101,"lastUpdatePostDateStruct":102,"startDateStruct":104,"completionDateStruct":106,"leadSponsor":108,"locationsCount":110},"100545078","understanding-aided-speech-perception-in-noise-100545078","NCT06377215","Understanding Aided Speech Perception in Noise","Understanding Aided Speech Perception in Noise: Behavioral and Electrophysiological Measures","Inclusion Criteria:\n\nTarget candidates for this study will be 38 young normal-hearing (YNH), 38 older normal-hearing (ONH), and 55 older hearing-impaired (OHI) subjects. Eligible NH listeners will have ≤20 dB HL at octave frequencies from 0.25 to 4 kHz and ≤30 dB HL up to 8 kHz. Eligible HI listeners will have bilateral (symmetric), moderate sensorineural hearing loss characterized by pure-tone thresholds between 35 to 50 dB HL from 0.25 to 2 kHz and 50 to 70 dB HL between 3 and 8 kHz. Age is restricted from 60 to 80 years for the older listening groups and from 18 to 35 for younger listeners. A balance of male and female participants will be recruited to assess sex as a biological variable in the data analyses. This age range for older listeners was chosen to be maximally inclusive of potential presbycusic participants, to promote generality of the results, and to facilitate uniform sampling within this age range. The investigators want to avoid the scientific need to stratify by age, which would make the scope of the project unmanageable given the constraints of this five-year award. The investigators have no evidence that lower or higher ages would affect aided intervention. Thus, inclusion of a larger age range would weaken the rigor of the investigation and complicate interpretation of the findings. The target range of hearing loss was chosen for similar reasons, reflecting the largest segment of older adults with hearing loss while avoiding the need to stratify by hearing loss to evaluate the stated hypotheses.\n\nAdditional Inclusion Criteria for HI group:\n\n* Bilateral sensorineural hearing losses within the mild-to-moderately severe range as indicated by pure tone air- and bone-conduction audiometry and screening (Y-226 Hz, Type \"A\") tympanograms.\n* Candidates for hearing aids or experienced users.\n* Fluent speaker of English as speech testing will be in English.\n* MoCA (Montreal Cognitive Assessment; Nasreddine et al., 2005) score of \\> 22. This cut point has been used frequently in investigations of aging and will better ensure that cognitive related problems will not restrict the abilities of subjects to perform the study tasks.\n\nExclusion Criteria:\n\nExclusion criteria include conditions for which one could anticipate that hearing or cognitive status might change markedly during the course of study. To hedge against such changes, participants will be excluded if they have undergone clinical management for any of the following in the past 12 months:\n\n* Head trauma\n* Traumatic brain injury\n* Epilepsy\n* Seizures\n* Other neurological disorders\n* Otologic surgical procedures\n* Actively fluctuating hearing loss\n* Acute Meniere's disease\n* Labyrinthitis\n* Conductive hearing loss\n* Use of ototoxic medications","80 Years",{"count":86,"type":22},121,[25],"The overarching hypothesis to be evaluated using this protocol is that age-related hearing loss (ARHL) leads to shifts in the functional spatial boundaries between segregated and integrated auditory streams, and that hearing aid intervention that relies on directional processing schemes is most effective for those that have the poorest spatial sensitivity. One key component of the research design is to measure both behavioral and neurophysiological indices of an individual's spatial segregation boundary. The second key component is to measure the cost or benefit associated with hearing aid intervention in older hearing-impaired listeners. The final component is to relate cost and benefit of hearing aid intervention to spatial sensitivity measures that might predict the efficacy of clinical intervention.",[90,39,91,92],"Hearing Impairment, Sensorineural","Aging","Hearing Aids",[94,95,96,97,98,99,100],"electrophysiology","binaural hearing","auditory scene analysis","auditory streaming","speech perception","localization","psychoacoustics","2025-12-19",{"date":103,"type":69},"2025-12-22",{"date":105,"type":69},"2025-11-16",{"date":107,"type":22},"2028-03-01",{"name":109,"class":76},"University of South Florida",1]
