Neural Networks

The video explores how neurons function individually and within networks, highlighting the concept of intrinsic activity. It explains that the brain is not merely a passive organ but has intrinsic activity structured by neural connections. The discussion includes the role of white matter, intrinsic networks, and network homeostasis, emphasizing that the brain's activity is not random but organized. Sensory deprivation is used to illustrate how the brain continues to generate sensations and thoughts even without external stimuli.

What is the primary difference between studying a single neuron and a network of neurons?

• Single neurons are larger than networks.

• Networks exhibit intrinsic firing, unlike single neurons.

• Single neurons do not require oxygen.

• Networks are less complex than single neurons.

How does the brain maintain activity in a sensory deprivation environment?

• By shutting down completely.

• By relying on visual input.

• By generating intrinsic activity.

• Through external stimuli.

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

• It prevents neurons from connecting.

• It is unrelated to intrinsic activity.

• It structures the intrinsic activity.

• It slows down neuronal firing.

What is network homeostasis?

• The ability of neurons to function independently.

• The process of neurons influencing each other to form a coherent network.

• The random firing of neurons.

• The breakdown of neuronal connections.

How do intrinsic networks in the brain change over time?

• They remain static throughout life.

• They evolve with experience.

• They are identical in all individuals.

• They disappear after birth.
