  • Spiking Neurons and the First Passage Problem
    LETTER Communicated by Daniel Tranchina Spiking Neurons and the First Passage Problem Lawrence Sirovich [email protected] Laboratory of Applied Mathematics, Mount Sinai School of Medicine, New York, NY 10029, U.S.A. Bruce Knight [email protected] Center for Studies in Physics and Biology, Rockefeller University, New York, NY 10065, U.S.A. We derive a model of a neuron’s interspike interval probability density through analysis of the first passage problem. The fit of our expression to retinal ganglion cell laboratory data extracts three physiologically rele- vant parameters, with which our model yields input-output features that conform to laboratory results. Preliminary analysis suggests that under common circumstances, local circuitry readjusts these parameters with changes in firing rate and so endeavors to faithfully replicate an input signal. Further results suggest that the so-called principle of sloppy work- manship also plays a role in evolution’s choice of these parameters. 1 Introduction The pattern of electrical discharge event times, recorded from a neuron by a microelectrode in a vertebrate’s central nevous system, largely depends on three macroscale parameters: local synaptic input current s, in response to signals from other neurons, the transmembrane ohmic rate constant γ , proportional to transmembrane conductance, and the intracellular level of stochastic voltage noise, which may be expressed as a diffusion coefficient. Here we develop an expression for a neuron’s interspike-interval proba- bility density distribution in terms of these three variables. Our procedure assigns to the recorded neuron a simplified dynamical model, whose input- output dynamics, in some studied cases, conforms well with laboratory results.

  • THE SUMMER MEETING in ITHACA the American Mathematical Society
    THE SUMMER MEETING IN ITHACA The American Mathematical Society held its seventieth summer meeting at Ithaca, New York from Tuesday through Friday, August 31-September 3, 1965. There were 1470 persons registered at the meeting including 1051 members of the Society. All sessions were held in lecture rooms and classrooms on the campus of Cornell Uni­ versity. Professor A. P. Calderón of the University of Chicago presented the Forty-Third Colloquium in a set of four lectures with the title Singular integrals. He was introduced at the first lecture by Professor A. A. Albert, President of the Society. Presiding at the other lectures were Professors R. H. Cameron, W. E. Sewell and J. W. Green, the last of whom offered the thanks of the Society to the speaker. By invitation of the Committee to Select Hour Speakers for Sum­ mer and Annual Meetings, Professor George Lorentz of Syracuse University addressed the Society on Applications of entropy to ap­ proximation. Professor Maurice Heins presided and introduced the speaker. There were twenty-six sessions for one hundred seventy con­ tributed papers. Members may wish to know that the number of papers offered for the program was exactly one hundred seventy, the same as the limit set in advance on the number which could be accepted. It was not necessary to turn down any papers for lack of a place on the program. The chairmen of the sessions for contributed papers were Pro­ fessors J. H. Bramble, R. J. Bumcrot, S. S. Cairns, S.
