Heavy marijuana users have abnormal brain structure and poor memory
Teens who were heavy marijuana users had abnormal changes in their brains related to memory and performed poorly on memory tasks, reports a new study. The brain abnormalities and memory problems were observed in the subjects' early twenties, two years after they stopped smoking marijuana, possibly indicating long-term effects. Memory-related structures in their brains appeared to shrink. The younger drug abuse starts, the more abnormal the brain appeared. The marijuana-related brain abnormalities look similar to schizophrenia-related brain abnormalities.

Sniffing out danger: Rutgers scientists say fearful memories can trigger heightened sense of smell
Neuroscientists at Rutgers University studying the olfactory -- sense of smell -- system in mice have discovered that fear reaction can occur at the sensory level, even before the brain has the opportunity to interpret that the odor could mean trouble.

Aging and gene expression -- possible links to autism and schizophrenia in offspring
Advanced paternal age has been associated with greater risk for psychiatric disorders, such as schizophrenia and autism. With an increase in paternal age, there is a greater frequency of certain types of mutations that contribute to these disorders in offspring. Recent research, however, looks beyond the genetic code to "epigenetic effects," which do not involve changes in the genes themselves, but rather in how they are expressed to determine one's characteristics.

Gene found to be crucial for formation of certain brain circuitry
Using a powerful gene-hunting technique for the first time in mammalian brain cells, researchers at Johns Hopkins report they have identified a gene involved in building the circuitry that relays signals through the brain. The gene is a likely player in the aging process in the brain, the researchers say.

Probiotic therapy alleviates autism-like behaviors in mice
Autism spectrum disorder (ASD) is diagnosed when individuals exhibit characteristic behaviors, decreased social interactions, and impaired communication. Curiously, many with ASD also suffer from gastrointestinal issues, like abdominal cramps and constipation. Guided by this co-occurrence of brain and gut problems, researchers at the California Institute Technology are investigating a bacterium that alleviates GI and behavioral symptoms in autistic-like mice, introducing a potentially transformative probiotic therapy for autism and other neurodevelopmental disorders.

Brain connectivity study reveals striking differences between men and women
A new brain connectivity study from Penn Medicine published today in the Proceedings of National Academies of Sciences found striking differences in the neural wiring of men and women that's lending credence to some commonly-held beliefs about their behavior.

Brain imaging differences in infants at genetic risk for Alzheimer's
Researchers at Brown University and Banner Alzheimer's Institute have found that infants who carry a gene associated with an increased risk for Alzheimer's disease tend to have differences in brain development compared to infants who do not carry the gene. The findings do not mean that these infants will get Alzheimer's, but they may be a step toward understanding how this gene confers risk much later in life.
