Neuroscientist conducts deep study of a brain, his own

Early this Tuesday morning, and every Tuesday morning through November 2013, neuroscientist Russell Poldrack will wake up, take off his headband-like sleep monitor, and tell it to wirelessly send data about his night’s sleep to a database.

Then he’ll log in to a survey app on his computer, and provide a subjective report on how well he slept, whether he’s sore, and what his blood pressure and pulse rate are. He’ll step on a scale, which will send his weight and

Texas collaboration started with lunch in Wisconsin

Adela Ben-Yakar, an engineering professor, and Jon Pierce-Shimomura, a neurobiology professor, have teamed up develop technology to test drugs for neurodegenerative diseases like Alzheimer's.

Adela Ben-Yakar, an engineering professor, and Jon Pierce-Shimomura, a neurobiology professor, have teamed up to develop technology to test drugs for neurodegenerative diseases like Alzheimer’s.

Scientific collaborations across disciplines can be great when they happen.

Researchers bring different skills, expertise and perspectives that can illuminate hard problems.

But just bringing different disciplines together can be a hard problem in itself, despite work being done by universities to break down the siloes that contain them.

So we wondered how Adela Ben-Yakar, a professor in the

Your brain, on drugs, learns too much

Hitoshi Morikawa want to find ways to interfere with the brain's capability to "overlearn" drug-associated behavior.One of the most famous science experiments is the one involving Pavlov and his dog in which Ivan Pavlov conditioned the dog to salivate at the sound of a bell.

Addictive drugs affect the brain in a similar but more powerful way, says Hitoshi Morikawa, a neurobiologist in the Waggoner Center for Alcohol and Addiction Research.

“We think addiction is a form of pathological overlearning in which the brain remembers too much the association between certain environmental stimuli and drug-seeking or drug-taking

When brain scans weigh in on body weight

Images from functional magnetic resonance imaging scans.

Images from functional magnetic resonance imaging scans.

The latest edition of Raw Science at the College of Natural Sciences website provides answers to the questions:

Can weight gain be predicted from looking at your brain with an fMRI?

Are “green” building materials more susceptible to destructive fungal growth?

It also dives into the genomes of radically different species in search of candidate genes for human diseases and tracks the lives of Pakistani paper wasps.

Batty love songs

George Pollak

The experiment began in a backyard barn. Instruments used included sophisticated recording equipment. A strong regimen of statistical analysis capped it off.

The result: evidence that suggests that male bats sing songs with distinguishable syllables and phrases to attract females, and in some cases, to warn other males to stay away. The paper written about the study was published in PLOS One.

The research was a collaboration of the owner of the barn, Barbara Schmidt-French of Bat Conservation International; George Pollak, a

Dr. Greg Allen’s research into autism is the upcoming research feature on the homepage of The University of Texas at Austin Web site.

Allen, a neuroscientist in the university’s College of Education, is trying to figure out what underlies the behaviors and symptoms of autism.

His uses magnetic resonance imaging (MRI) to investigate the ways in which the cerebellum of a person with autism differs from that of a non-autistic person, and then to examine how that pathology contributes
