A Unique Approach to Lifespan Diagnosis: The Psychological Autopsy
Many Pitt Psychiatry scientists use postmortem human brain tissue to identify neural alterations associated with mental disorders to guide the development of novel treatments. They do so with confidence that a team of psychologists and psychiatrists have systematically validated the diagnoses of each donor subject. This lifespan review is an uniquely intensive version of a process known as the “psychological...
New Research in the Journal of Psychopharmacology: Cannabis Use and Working Memory Impairments in Adolescents
As cannabis use increases, questions remain about its impact on users’ cognitive function. Studies have shown that among adolescents, the use of cannabis—specifically its primary psychoactive ingredient, Δ-9-tetrahydrocannabinol (THC)—can be associated with susceptibility to cognitive impairment. Previous research has examined the effects of THC on working memory and other cognitive processes in adolescence, but...
Now in The Journal of Neuroscience: Regional Differences among Pyramidal neurons in the Working Memory Cortical Network
Working memory, the ability to maintain a limited amount of information “in mind” to guide everyday thoughts and behaviors, is a core cognitive process. Its function depends on activity in a network of brain areas distributed across the cerebral cortex. Each of these areas display different patterns of activity while information is being maintained. These differences are correlated with, and might depend on...
Now in Molecular Psychiatry: Department Investigators Uncover Molecular Alterations in Obsessive-Compulsive Disorder
Obsessive-compulsive disorder (OCD) is a disabling illness characterized by obsessions that result in compulsive behavior. Underscoring the need for more effective treatments, existing first-line therapies lead to remission in just 10–15% of patients. However, the development of new therapies requires a better understanding of the molecular abnormalities that are present in OCD. A recent study from Pitt Department...
