Study uses fMRI scans to analyze the role of the human hypothalamus in switching between hunting and escaping behaviors in a virtual survival game
In the new study, the researchers developed artificial-intelligence-based approaches to optimize and analyze fMRI scans of the brains of 21 healthy individuals, taken over four-hour periods while people were engaged in a hunting and escaping survival game within the fMRI scanner. Participants had to control an avatar, switching between hunting prey and escaping a predator.
The authors conclude that the hypothalamus plays a key role in how the human brain switches between and coordinates survival behaviors -- a function that is important and evolutionarily advantageous. A new study has implicated several genes involved in a variety of bodily functions associated with the hypothalamus, a notoriously difficult-to-study region of the brain. The findings could help ...
