Brain Circuit Involved in Fentanyl Abuse and Relapse Identified

Fentanyl enhances direct pathway medium spiny neurons activity in the striatum. During withdrawal from the opioid, inhibitory signals from direct pathway medium spiny neurons to dopaminergic neurons become enhanced. The enhanced suppression of dopaminergic neurons contributes to the negative emotions associated with fentanyl withdrawal. Inhibiting the direct pathway medium spiny neurons can reduce withdrawal symptoms and associated anxiety behaviors.

How Huntington’s Disease Affects Different Neurons

Researchers have identified how two different populations of neurons in the striatum are affected differently in Huntington's disease. The neurodegeneration of one of these populations leads to motor defects while damage to the other population located in striosomes may account for mood disorders associated with the early stages of Huntington's.

Psychopaths Are More Likely to Have a Larger Striatum

Neuroimaging study reveals those with psychopathy have a 10% larger striatum than non-psychopaths. Researchers say the increased size of the striatum, a brain area associated with cognitive and social functions, may account for a higher likelihood of impulsive behaviors and increased need for stimulation often associated with psychopathy. Additionally, researchers suggest there may be an element of heredity in the neural anatomy, adding support to the neurodevelopmental perspective of psychopathy.

Familiar Objects Can Prevent Autism-Like Behaviors in Mouse Model

Exposing mice with the autism-associated SHANK3 genetic mutation to new environments can trigger autism-like behaviors, including repetitive movements and problems with social engagement. However, adding familiar objects to the novel environment during the first exposure can reduce the behavioral and brain signaling deficits.
