2. Transient Probability Distributions of Nerve Impulse Intervals, S. B. Thesis, Department of Physics, M.I. T., June 1964. The time evolution of the distribution of nerve-impulse intervals was examined by measuring histograms at varying times in the stimulus cycle. The distribution width was found to vary inversely as the stimulus strength. There is an indication that the width also depends up...

Xxi. Neurophysiology A. Color Vision I

0 0 The range of visible light lies between 4000 A and 7000 A wavelength. Extremely powerful radiation above and below those limits can be seen, but these are the commonly accepted extrema. Within that band the spectral distribution of power in a ray of light describes some of its qualities. The color that is perceived seems to be related to that spectral distribution. Two of the operations tha...

Graph minors. XXI. Graphs with unique linkages

A linkage L in a graph G is a subgraph each component of which is a path, and it is vital if V (L) = V (G) and there is no other linkage in G joining the same pairs of vertices. We show that, if G has a vital linkage with p components, then G has tree-width bounded above by a function of p. This is the major step in the proof of the unproved lemma from Graph Minors XIII, and it has a number of ...

Lecture XXI: Radial pulsations and stability

Having constructed the equilibrium stellar configurations, we are now poised to ask whether they are stable to small perturbations. This leads us to the subject of relativistic stellar pulsations. One may classify such pulsations by their angular dependence: when we investigate the full subject we will find modes of every spherical harmonic index l ≥ 0. However, for the cold stars of interest t...
