    This lesson introduces the concept of constraints on information processing, and how studying these constraints can reveal valuable knowledge about how the brain and other systems function. 

    Topics covered in this lesson
    • Shannon's information and entropy
    • Examples of amplification, low pass filtering in biological circuits
    • Biological limits and constraints on processing - energy density, noise
    • Analogue signal quality and information rate
    • Biological "cost per bit" vs signal rate; information cost vs cell size
    • Reversible computation
    • Efficiency of chemical computation vs electrical computation
    • Phylogenetic constraints
    Prerequisites
    • Familiarity with concepts of entropy, free energy
