Neuromodulation of Conscious Perception: Investigating Thalamic Roles Through Ultrasonic Stimulation

Neuromodulation of Conscious Perception: Investigating Thalamic Roles Through Ultrasonic Stimulation

The purpose of this study is to evaluate the role that the thalamus (the egg-shaped structure in the middle of your brain) plays in perception using a low-intensity ultrasound pulsation (LIFUP) device. The researchers expect to observe differential changes in the perceptual outcomes based on the LIFUP stimulation of different thalamic areas

Inclusion Criteria:

• Must be right-handed.
• Must have normal or corrected-to-normal vision (while wearing contact lenses). Please note: persons who need eyeglasses to achieve 20/20 vision cannot be included in this study as eyeglasses cannot be worn during the study visit.

• Must be English speaking.
• Must be capable of giving written informed consent.

Exclusion Criteria:

• Vision that is not 20/20, or vision that is not corrected to 20/20 while wearing contact lenses.

Please note: persons needing eyeglasses to achieve 20/20 vision cannot be included in this study as eyeglasses cannot be worn during the study visit.

• History of significant head injury with loss of consciousness.
• Learning disability or other developmental disorder.
• Medication use for any neurological, psychological, or psychiatric conditions.
• Any impairment (sensory or motor loss), activity, or situation that in the judgment of the study coordinator or Principal Investigators would prevent satisfactory completion of the study protocol.
