Jennifer DeLosSantos Beta #12 Long-term marijuana use changes brain's reward circuit The people who conducted this research are from the Center for Brain Health. Researchers have demonstrated that long-term marijuana users had more activity in the brain's reward processes when presented with cannabis cues than with natural reward cues. Researchers studied 59 adult marijuana users and 70 nonusers, accounting for potential biases such as traumatic brain injury and other drug use. Study participants rated their urge to use marijuana after looking at various visual cannabis cues, such as a pipe, bong, joint or blunt, and self-selected images of preferred fruit, such as a banana, an apple, grapes or an orange. Researchers also collected self-reports from study participants to measure problems associated with marijuana use. On average, marijuana participants had used the drug for 12 years. They found that this disruption of the reward system correlates with the number of problems, such as family issues, individuals have because of their marijuana use. Every important because a lot of people have long term use or are beginning to use this drug in high school not knowing the effects. Center for BrainHealth.

Cannabis use during pregnancy may affect brain development in offspring: Thicker prefrontal cortex The source of this research is Elsevier and Dr. Hanan El Marroun, of Erasmus University Medical Center in The Netherlands. Cannabis use during pregnancy is associated with abnormal brain structure in children, according to a new study. Compared with unexposed children, those who were prenatally exposed to cannabis had a thicker prefrontal cortex, a region of the brain involved in complex cognition, decision-making, and working memory. In the recently published study, the researchers used structural magnetic resonance imaging to examine the brains of 54 children, 6 to 8 years old, who were prenatally exposed to cannabis. Most of the children exposed to cannabis were also exposed to tobacco, so the researchers compared them to 96 children prenatally exposed to tobacco only, as well as to 113 control children with no exposure.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
