Eligibility Criteria
Inclusion
- INCLUSION CRITERIA:
- Normal healthy volunteers in this protocol should be fluent English speaking and have at least 12 years of education.
- Subjects should also be right-handed.
- EXCLUSION CRITERIA:
- People who are not native speakers of English or are left handed will be excluded from this study.
- Given the nature of the stimuli presentation (i.e., projected visual images and speakers carrying voice), anyone with noncorrectable vision impairments, hearing loss, or known risk for hearing loss will be excluded. Normal hearing is defined as hearing thresholds of 25dB HL or less for the octave frequencies 250 - 8000 Hz and intact crossed acoustic reflex in both ears.
- The dual focus of this research on sleep deprivation and fMRI yields additional sets of exclusion criteria for both fMRI safety and normal sleep/wake patterns. Given the dimensions of the fMRI and the exam table, anyone whose body size or shape cannot be accommodated in the fMRI with a projected image remaining continuously visible will be excluded.
- Women who are pregnant will be excluded from this protocol.
