Ch 4 (3) Neurons and the Brain

Question 1

What was one of the first large-scale brain simulations?

Answer 1

Task-tailored engineering computer simulation of the visual cortex

Question 2

Three things to know about the model for the simulation of the visual cortex

Answer 2

• processes input from a color camera

- solves the binding problem

Question 3

binding problem

Answer 3

The consciousness and binding is the problem of how objects, background and abstract or emotional features are combined into a single experience.

Question 4

What can the thalamocortical brain model reproduce

Answer 4

typical patterns of brain activity

Question 5

What can Spaun model do?

Answer 5

the model implements cognitive functions like image recognition, working memory, perception and action
- focus of model is on production of behavior

Question 6

What is the problem with all the brain models developed so far?

Answer 6

They are largely decouples as the correspond to different directions of research.
It is hard to incorporate new findings or extend them.
–> Need for flexible unified model that captures all knowledge which can easily be extended

Question 7

What did the Blue Brain Project develop?

Answer 7

Data-driven reconstruction process for cortical microcircuits.
- Digital reconstruction that is based on experimental data and predictions
