Out of Thin Air

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 is the primary role of white matter in the brain?

• To store memories

• To speed up neural conductivity

• To produce hormones

• To regulate emotions

What happens to the brain's intrinsic activity in a sensory deprivation chamber?

• It only processes auditory information

• It stops completely

• It continues with sensations and thoughts

• It becomes chaotic

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

• Default mode network

• Salience network

• Control network

• Limbic network

What is the function of limbic tissue in the brain's predictive hierarchy?

• To control muscle movements

• To process auditory information

• To regulate internal physical states

• To store long-term memories

Where is limbic tissue most concentrated in the brain?

• In the motor cortex

• In the default mode and salience networks

• In the visual cortex

• In the auditory cortex

What is one of the key functions of the default mode network?

• Conceptual processing

• Motor control

• Auditory processing

• Visual processing

How does Alzheimer's disease affect the default mode network?

• It enhances its activity

• It has no effect

• It causes it to atrophy

• It strengthens its connections
