Networks, Limbic Tissue & Memory

The video explores the brain's intrinsic activity and its structured networks, emphasizing the role of limbic tissue in predictive hierarchies. It discusses intrinsic networks like the default mode and salience networks, highlighting their importance in cognitive functions and memory. The video also touches on the implications of these networks in conditions like Alzheimer's disease.

What does the brain's intrinsic activity suggest about its need for external stimulation?

• External stimulation is harmful to brain activity.

• The brain can generate activity without external stimulation.

• The brain requires constant external input to function.

• The brain's activity is entirely random without external input.

What role does white matter play in the brain's intrinsic activity?

• It slows down neural conductivity.

• It is unrelated to neural activity.

• It only affects sensory neurons.

• It structures the brain's intrinsic activity.

Which network is known to increase its activity when something is particularly relevant or important?

• Limbic network

• Default mode network

• Salience network

• Control network

What is the primary function of limbic tissue in the brain?

• To control motor functions

• To regulate internal physical state

• To process visual information

• To enhance auditory processing

How is limbic tissue positioned in the brain's predictive hierarchy?

• In the middle, processing predictions

• Outside the hierarchy, unrelated to predictions

• At the top, sending predictions

• At the bottom, receiving predictions

Which networks contain the majority of limbic tissue in the brain?

• Control and sensory networks

• Motor and auditory networks

• Visual and auditory networks

• Default mode and salience networks

What happens to the default mode network in Alzheimer's disease?

• It enhances memory function.

• It becomes more active.

• It starts to atrophy.

• It remains unchanged.
