Free recall

"Neural model" with sparseness

discussion: mechanistic network vs. abstract graph


Individual person parameters

Limit of sparse

Universal formula

Non universal results

Why? Recognition as normalization


Possible extensions?

Reaction time - either stochastic, or 



Working memory

Computational challenge:

prolong beyond natural timescale



Persistent activity

Positive feedback

Eigenvalues and effective timescale

Can slow down and also cause bistability


Discrete vs. continuous



Bump attractor dynamics

CRITICAL: why no drift before 3 seconds? Motor?
