Brain Networks Trivia

Which of these is the Default Mode Network not involved in?

• Theory of Mind

• Constructing an imagined Scene

• Self-referential processing

• Working memory

What are the key roles of the Salience network?

• Monitoring the quality of external inputs and internal brain events.

• Prevent goal-driven attention from being distracted by non-relevant stimuli

• Helping to change between Default Mode network functioning and Control network

• All of the above

Default Mode Network is responsible for

• Agency

• Empathy/Theory of Mind

• Reorienting

• All of the above

How many core large-scale brain networks have been found through fMRIs of the brain?

• 3: Default Mode network, Executive Control network, Salience network

• 10: Default Mode network, 2 Executive Control networks, Salience network, Sensorimotor network, Auditory network, 3 Visual networks, Cerebellum network

• 5: Default Mode network, Executive Control network, Salience network, Sensory network, Motor network

• 6: Default Mode network, Salience network, Attention network, Control network, Somatomotor network, Visual network

Which of the following is not true about the differences between the Dorsal Attention network (DAN) & Frontoparietal network (FPN)?

• The DAN is involved in voluntary orienting of visuospatial attention & FPN is involved in rule-based problem solving

• An underactive DAN leads to schizophrenia and disruption of FPN is involved with ADHD

• Both the DAN and the FPN are involved in goal-oriented tasks

• The DAN's core regions are the Intraparietal Sulcus (IPS) & the Frontal Eye Fields (FEF) & the FPN's core regions are the lateral prefrontal cortex (lPFC) and the inferior parietal lobule

The Sensorimotor network (SMN) is involved in motor tasks, such as finger tapping. Which of these disorders has a dysfunction of the SMN been implicated in?

• Schizophrenia

• Amyotrophic Lateral Sclerosis (also known as Motor Neurone Disease)

• Major Depressive Disorder

• Tourette's (characterised by movement and vocal tics)

Which of the following is an imaging technique not used to analyse large-scale brain networks

• Functional Magnetic Resonance Imaging (fMRI)

• Magnetoencephalography (MEG)

• Positron emission tomography (PET)

• X-rays
