In neural integrators, transient inputs are accumulated into persistent firing rates that are a neural correlate of short-term memory. Integrators often contain two opposing cell populations that increase and decrease sustained firing as a stored parameter value rises. A leading hypothesis for the mechanism of persistence is positive feedback through mutual inhibition between these opposing pop...

These lecture notes are intended to recapitulate class lectures. Several notational considerations exist. Namely, appendices to lectures generally provide information not found in the lecture, but are nonetheless helpful for producing a more rigorous understanding of the material; an * (asterisk) next to a proposition, definition, theorem, etc. indicates it was not explicitly written (or mentio...

Molecular recognition on supramolecular systems (XXXV)

A novel β-cyclodextrin derivative 4 bearing a pyridinio group on the primary side was synthesized by the reaction of 2-aminopyridine with 6-β-cyclodextrin monoaldehyde 3, and its complexation stability constants with several aliphatic amino acids have been determined in phosphate buffer solution ( pH = 7.2, 0.1 mol L) at 25 by using spectrofluormetric titrations. The stoichiometry is 1 1 for th...

Accurately maintaining a fixed limb posture and quickly moving between postures underlies both everyday skills, including holding and lifting a cup of coffee, and expert skills, such as an Olympic wrestler’s holding and throwing an opponent. A fundamental question in limb motor control is whether the brain manages these contrasting goals of posture and movement through a single, robust control ...
