Versus Brain Blast | May 2019

What defines our lives? It is the job we do, the emotions we feel, the sensations we experience, or the way our body functions?

In the recent articles we have compiled below, scientists examine life through the lenses of neurobiology and psychology to better understand how our brains, our bodies, and our environments shape who we are and how we act. We hope this research will teach, challenge, surprise, and, ultimately, aid you on the path to living your best life.

On the Job: Decision Making in the Police Force

In an effort to improve officer training, a research team is working with the Cleveland Police Department to explore how high-stress situations impact officers’ decisions in relation to use of force. They will simulate increasingly stressful incidents in VR and measure officers’ brain activity via EEG technology.

Back to Life: Reviving Dead Brain Cells

Red blood cells.
Researchers at Yale were able to revive cellular activity, but not that associated with consciousness, in the severed brain of a pig four hours after it had died. In the future, this development may allow scientists to conduct valuable experiments on cellularly active brains without concern for the rest of the body.

In Your Dreams: Emotional Expression in Sleep

Brain activity associated with anger while asleep looks the same as anger while awake, according to a recent study. By extension, it may be possible to improve people’s feelings during waking hours by using brain stimulation to regulate the emotions they experience in their sleep.

Caffeine-Free: Cues to Replace Coffee

Simply being exposed to cues that remind them of coffee can make coffee drinkers feel more alert, focused, and engaged. A phenomenon called priming, this occurrence may be of particular interest to marketers looking to understand and influence consumer behavior.

Brain Changer: Vision Impairment and Hearing Enhancemen

Using fMRI technology, a UW research team discovered that individuals who are born blind have increased activity in the auditory cortex and hMT+ regions of the brain. As a result, they are significantly better than sighted people at noticing subtle differences in sound frequency and tracking motion of objects via sound.
