Neuroimaging predicts whether a person with OCD will respond to stress-reduction therapy or exposure-based therapy best. Analyzing brain activity may help to provide tailored treatments to individuals suffering from OCD.
People with schizotypal traits exhibited increased structural connectivity probability within the task control network and default mode network. They also had increased variability and decreased stability of functional connectivity within the DMN and between the auditory and subcortical networks.
Neuroimaging pinpoints areas of the brain that regulate efforts to deal with fatigue. The study reveals the neural mechanisms that contribute to feelings of fatigue.
Synchronized activity between the ventromedial prefrontal cortex and temporoparietal junction improves learning and decision-making when people try to avoid harming others.
Using transcranial alternating current stimulation, researchers were able to influence the activity of specific brain areas and manipulate the abilities processed by them. Findings suggest tACS could be used to improve, direct, and attenuate the flow of information in the brain.
Using data from MRI brain scan images, machine learning was 85% accurate at providing a diagnosis of psychiatric disorders that matched psychiatrists' assessments. The algorithm could also distinguish between patients with ASD, schizophrenia, risk factors for psychosis, and those with no history of mental health problems.
Aging may alter neural processes for remembering continuous real-world experiences and segmenting memories.
Males with autism have atypically enhanced excitation in the medial prefrontal cortex (mPFC). This area of the brain is associated with social cognition and self-reflection. Autistic women showed a more intact mPFC response, which was associated with a better ability to camouflage social difficulties in real-world settings.
Compared to typically developing children, those with disruptive behavioral disorders, characterized by antisocial behaviors and aggression, had less gray matter in the amygdala and hippocampus.
High resolution imaging reveals the human cerebellum is 80% of the area of the cortex. The findings indicate this area of the brain likely grew larger as human behavior and cognition evolved.
Those with MS allocate neural resources less effectively when faced with increased cognitive task demands, and this likely results in the increased mental fatigue those with the neurodegenerative disorder experience.
Cortical thickness and regional brain connectivity pay an equally important role in linking brain and behavior.
