Ode to the brain Human vs computer

Ode to the brain

Human vs computer centered

Introduction

Example: Pattern Recognition

Is the brain a computer?

Von Neumann computers

Issue 1. Centralized control

But this way …

Example: Visual processing

The results - No “CPU”!

“It does not compute” ?

Subsystem autonomy

IS autonomy examples

Design principles

Issue 2. Sequential processing

Massively parallel processing

Neurons are slow

The parallel advantage

Design principles

Issue 3. Single IO processing

The case of Phineas Gage

Reliability

Blindsight

Conclude

Example

IS example: Operating systems

Design principles

Lashley’s “engram” search

Human memory

Memory and connections

Neurons

Connectivity

Example

Massive interconnection

Advantages of ABC

Design Example - Hypertext

Issue 5. Input driven

Input driven system (IPO)

The curse of context

Active systems
