Eitan is a postdoctoral fellow studying memory and sleep in Dr. Ken Paller's Cognitive Neuroscience lab at Northwestern University. I graduated from the Hebrew University in Jerusalem with a BA in Psychology and a MSc and PhD in Neural Computation.
In the practical use of our intellect, forgetting is as important a function as recollecting.
- William James
- I use neuroimaging combined with unobtrusive cuing during sleep to examine:
- The capacity to reactivate multiple memories during sleep.
- The role of context in sleep-related memory reactivation.
- The dynamic interaction between multiple reactivated memories.
- The implications these issues have on the neural mechanisms involved in sleep-related memory reactivation.
- Using these same techniques, I address the following questions:
- Do some memories deteriorate over sleep?
- What are the determining factors as to which memories weaken over sleep?
- Is there a tradeoff between memories enhanced and weakened over sleep?
- Can sleep be manipulated to selectively facilitate memory deterioration?
- If so, can these methods be used to enhance or accelerate treatments for anxiety disorders or post-traumatic disorder?
