Your brain transmits information about your current location and memories of past locations over the same neural pathways using different frequencies of a rhythmic electrical activity called gamma waves, report neuroscientists at The University of Texas at Austin.

Brain Scans Show We Take Risks Because We Can't Stop Ourselves

Brain Scans Show We Take Risks Because We Can't Stop Ourselves

A new study correlating brain activity with how people make decisions suggests that when individuals engage in risky behavior, such as drunk driving or unsafe sex, it's probably not because their brains' desire systems are too active, but because their self-control systems are not active enough.

Grasshopper Mice Are Numb to the Pain of the Bark Scorpion Sting

Grasshopper Mice Are Numb to the Pain of the Bark Scorpion Sting

The painful, potentially deadly stings of bark scorpions are nothing more than a slight nuisance to grasshopper mice, which voraciously kill and consume their prey with ease. When stung, the mice briefly lick their paws and move in again for the kill.

Socially Isolated Rats are More Vulnerable to Addiction, Report Researchers

Social isolation during a key period of adolescence increases vulnerability to addiction as well as the difficulty of extinguishing it.

Alcoholic Fly Larvae Need Fix for Learning

Alcoholic Fly Larvae Need Fix for Learning

Fly larvae fed on alcohol-spiked food for a period of days grow dependent on those spirits for learning.

A collaboration between a college biologist and researcher at St. David's HealthCare could someday lead to personalized treatments for a deadly form of brain cancer.
Memories Serve as Tools for Learning and Decision-Making, New Study Shows

Memories Serve as Tools for Learning and Decision-Making, New Study Shows

Alison Preston, of the Center for Learning and Memory, shows that when humans learn, their brains relate new information with past experiences to derive new knowledge.

Waggoner Center Wins Grant to Develop Drug to Treat Addiction

Researchers have received a $3.3 million to develop medication to treat alcoholism and drug addiction that could target individual genes or brain signaling systems.
