My name is David E. Warren and I’m a cognitive neuroscientist at the University of Nebraska Medical Center. I study memory and brain networks by combining neuropsychological and neuroimaging methods.

Hubs in brain networks

Functional neuroimaging studies have identified many different brain regions as potential hubs, but does damage to “hubs” alter cognition?

vmPFC and false memory

The ventromedial prefrontal cortex (vmPFC) participates in schematic memory processes, and damage to vmPFC can reduce false memory.

Relational memory and hippocampus

Hippocampus is critical for remembering arbitrarily related pieces of information, and hippocampal damage causes amnesia.

MTL and on-line processing

The same brain regions that support memory also contribute to our ongoing cognition and behavior in unexpected ways.

Word learning in amnesia

Amnesia slows or stops most learning, but novel teaching methods may allow memory-impaired patients to learn new words rapidly.

Age and eye movements

Eye movements change with healthy aging, but neurological disorders such as Alzheimer's may cause unique changes allowing early detection.
