Widespread Connections Among Neurons Help the Brain Distinguish Smells
Researchers say the randomness of the piriform cortex plays a critical role when it comes to distinguishing between similar odors.... Read More...
How the Brain Responds to Cold Touch
A new study could help advance research into pain and hypersensitivity to cold stimuli. Researchers have mapped feelings of cold touch sensation in the insula of mice.... Read More...
A Rose is a Rose is a Rose: Mathematical Model Explains How Different Brains Agree on Smells
A new computational model sheds light on the complexity of smell identification. Researchers report different brains know how to associate new similar odors, so long as they have experienced an overlap in odors over their lifetime.... Read More...
Amphetamine Abuse Disrupts Development of the Prefrontal Cortex: Mouse Study
According to a new study to be published in eNeuro, amphetamine use may disrupt the development of the orbital prefrontal cortex, an area of the brain associated with decision making.... Read More...
How Odors Are Turned into Long Term Memories
A new study reveals the piriform cortex is able to archive long term memory, but requires instruction from the orbiotfrontal cortex to indicate the event is to be stored as a long-term memory.... Read More...
