Speech Tasks for Speech Perception
Trial Summary
What is the purpose of this trial?
The basic mechanisms underlying comprehension of spoken language are still largely unknown. Over the past decade, the study team has gained new insights to how the human brain extracts the most fundamental linguistic elements (consonants and vowels) from a complex and highly variable acoustic signal. However, the next set of questions await pertaining to the sequencing of those auditory elements and how they are integrated with other features, such as, the amplitude envelope of speech. Further investigation of the cortical representation of speech sounds can likely shed light on these fundamental questions. Previous research has implicated the superior temporal cortex in the processing of speech sounds, but little is known about how these sounds are linked together into the perceptual experience of words and continuous speech. The overall goal is to determine how the brain extracts linguistic elements from a complex acoustic speech signal towards better understanding and remediating human language disorders.
Eligibility Criteria
This trial is for individuals at UCSF with epilepsy or brain tumors who are undergoing surgical electrode implantation. They must have electrodes in at least two key brain areas and be able to perform study tasks. Those unable to consent, with significant cerebral lesions, or cognitive deficits that prevent task completion cannot participate.Inclusion Criteria
