The Cognitive Neuroscience Laboratory (CNL) is a multidisciplinary research laboratory that studies the neural underpinnings of human behavior primarily using magnetic resonance imaging (MRI). Our two focus areas are cognition in the setting of sleep deprivation, and the cognitive neuroscience of aging. In addition to our own research, we support a number of other investigators.

To investigate the relationship between regional hippocampal volume and memory in healthy elderly, 147 community-based volunteers, aged 55-83years, were evaluated using magnetic resonance imaging, the Groton Maze Learning Test, Visual Reproduction and the Rey Auditory Verbal Learning Test. Hippocampal volumes were determined by interactive volumetry. [Download article]

Most prior studies on selective attention in the setting of total sleep deprivation (SD) have focused on behavior or activation within fronto-parietal cognitive control areas. Here, we evaluated the effects of SD on the top-down biasing of activation of ventral visual cortex and on functional connectivity between cognitive control and other brain regions.

Volunteers Needed!
We are seeking volunteer participation for this current research study:
Attention and Visual Processing in Sleep Deprivation
This study will take place over approximately 2 weeks, and volunteers will undergo 2 magnetic resonance imaging (MRI) scanning sessions, with one session being an overnight sleep deprivation session.
If you are between 21 to 35 of age, with no chronic illnesses and have regular sleeping patterns (at least 6.5 hours of sleep every night), please fill up the sleep questionnaire here to take part in our study.
