The age at which an adolescent begins using marijuana may affect typical brain development, according to researchers at the Center for BrainHealth at The University of Texas at Dallas. In a paper recently published, scientists describe how marijuana use, and the age at which use is initiated, may adversely alter brain structures that underlie higher order thinking.

Between the rise of 3D movies and virtual reality, more and more people are getting a chance to don goofy glasses or headsets and experience media in three dimensions. And many of those people are discovering something about themselves: 3D makes them ill. Sitting in the theater or on their own couch, they get a sensation like motion sickness. They might feel nausea, dizziness, or disorientation.
A new study suggests that these symptoms aren't weakness on the part of the viewer. People who... Read more »

Album artwork for Dion McGregor Dreams AgainThe "most extensive sleep talker ever recorded", according to a new article in Imagination, Cognition and Personality, is the late American songwriter Dion McGregor. McGregor's unusual sleeping behaviour – one commentator said he "sounds as if he were channeling Truman Capote on acid: flirtatious, slushy, disconnected from reality ..." – first became public in the 1960s when McGregor shared a New York apartment with a posse of o........

Two papers provide some blogging fodder today. The first is from Agnieszka Rynkiewicz and colleagues  (open-access available here) who introduces a concept that many people with an interest in autism might have considered: a 'female camouflage effect' in autism. The second paper is by C Ellie Wilson and colleagues  and continues the idea that sex/gender differences present in autism might have some important implications for diagnostic evaluation.Both these papers entertain ........

Happy year of the monkey! Last time in the Petri dish, I considered the replicator dynamics between type-A and type-B cells abstractly. In the comments, Arne Traulsen pointed me to Li et al.

Human and animal movements generate slight neural signals from their brain cells. These signals obtained using a neural interface are essential for realizing brain-machine interfaces (BMI). Such neural recording systems using wires to connect the implanted device to an external device can cause infections through the opening in the skull. One method of solving this issue is to develop a wireless neural interface that is fully implantable on the brain.

The longest autobiographical narratives were produced by men talking to women Prior research has found that women elaborate more than men when talking about their autobiographical memories, going into more detail, mentioning more emotions and providing more interpretation. One problem with this research, though, is that it hasn't paid much attention to who is listening or whether the memories are spoken or written.This is unfortunate because findings like these can fuel overly sim........

Babies have an unusual ability to see those things and differences in pictures that are not visible to adults.
In a study conducted by researchers from Japan, it has been reported that infants under 5 months of age have an ability to detect changes in pictures or images that are not visible to adults. However, this ability disappears rapidly, and infants in the age range of 5 months to 6 months are unable to detect image dif........ Read more »
