What we don’t know: Neuroscience research at CMHC

The third floor of the CMHC houses the Clinical Neuroscience Research Unit (CNRU), an inpatient and outpatient research facility. It’s an honor to be asked to start a dialogue with you about what we do on the CNRU. Over the next few months, I’d like to introduce you to the scientists and clinicians and their teams that work on the CNRU. Today I’d like to introduce you to some of the things we do on the 3^rd floor.

Just as others in the building, my CNRU colleagues and I come to work to tackle the problems addressed on the other floors of the CMHC: the debilitating symptoms of mental illness including depression, hallucinations, delusions, drug addiction and anxiety to name a few. (more…)

Get off my lawn: Song Sparrows Escalate Territorial Threats

Territorial song sparrows use increasingly threatening signals to ward off trespassing rivals. First an early warning that matches the intruder’s song, then wing waving – a bird’s version of “flipping the bird” – as the dispute heats up, and finally, if all other signals have failed, attack.

This hierarchical warning scheme, discovered by researchers at the University of Washington, adds nuance to a communication system that has been long-used as a model to study how people use and learn language (more…)

Brain shows diminished response to untrustworthiness, UCLA scientists report

Why are older people especially vulnerable to becoming victims of fraud? A new UCLA study indicates that an important clue may lie in a particular region of the brain that influences the ability to discern who is honest and who is trying to deceive us.

Older people, more than younger adults, may fail to interpret an untrustworthy face as potentially dishonest, the study shows. The reason for this, the UCLA life scientists found, seems to be that a brain region called the anterior insula, which is linked to disgust and is important for discerning untrustworthy faces, is less active in older adults.
