Neuronal communication: Presynaptic terminals as transmitter array
No full textIn this paper, a communication engineering model is proposed for capturing the actual behavior of biological neurons by accounting for the specific and unique processing performed by the presynaptic terminals. Specifically, experimental evidences show that: i) the release sites from a single axon can have variable release probabilities, even when the axon contacts the same postsynaptic neuron; ii) this variability in the release probability implies a compartmentalization at the level of the presynaptic terminals of the neuronal processing; iii) the specificity of the presynaptic terminal processing is driven by and reflects the complex biophysical mechanisms activated at the axon terminals by the spikes fired by the neuron in response to a stimulus. Stemming from these experimental evidences, we propose to model the presynaptic terminals as an array of transmitters, where each transmitter models the specific processing made by a presynaptic terminal. We conduct the analysis through a stochastic approach, since the synaptic transmission is inherently stochastic. In particular, we first analytically characterize the stochastic filtering of the spike train performed by each presynaptic terminal. Then, we characterize the propagation of the presynaptic-filtered signal through the synaptic cleft, and we derive the signaling delay as a function of the distance between the pre- and the postsynaptic neurons. Finally, the conducted theoretical analysis is validate through numerical simulation
Modeling the dynamic processing of the presynaptic terminals for intrabody nanonetworks
No full textExperimental evidences show that: 1) the release sites from a single axon have variable release probabilities, even when the axon contacts the same postsynaptic neuron; 2) this variability in the release probability implies a compartmentalization at the level of the presynaptic terminals of the neuronal processing; 3) the specificity of the presynaptic terminal processing is driven by and reflects the complex biophysical mechanisms activated at the axon terminals when a spike is fired in response to a stimulus. Stemming from these experimental evidences, we propose a communication engineering model for capturing the behavior of biological neurons. Specifically, by adopting a stochastic approach, the presynaptic terminals are modeled as a dynamic array of transmitters, where each transmitter models the processing specificity of a presynaptic terminal. In particular, we first show that the unique and specific processing of a presynaptic terminal can be reconducted to the cascade of a frequency selector and an amplitude modulator. Then, we characterize the propagation of the presynaptic-filtered signal through the synaptic cleft, and we derive the delay along with the channel attenuation as a function of the distance between the communicating neurons. Finally, the theoretical analysis is validated through numerical simulation
La Vestale 'incesta'
No full textMarcello Salvadore: La Vestale incesta.
Dionysius of Halicarnassus, Pliny the Younger and Plutarch are the sources
of a detailed account of Vestalis incesta’s punishment: they say that she was
sentenced to death. Dionysius adds that there was no after death ritual.
Modern scholars generally accept what the three authors assert. In this article
the author surmises that the Vestalis incesta, together with the parricida, was
not condemned to death: both of them were sentenced to a particular kind
of banishment from the Society
De Lope a Celano: la adaptación italiana de "Los tres diamantes"
No full textAbstract
This paper explores an Italian adaptation of Lope de Vega’s play Los tres diamantes, written in the
second part of the seventeenth century. Its author, Carlo Celano, was a famous writer of opere regie,
i.e., adaptations of Spanish comedies of situation. The analysis focuses on the way in which the
adaptation of the Aristotelian units of space and time leads to a reduction of the characters and a
simplification of the situation, although this is compensated by enriching its ludic component. This
last trait can be also observed in a previous re-elaboration of Lope’s comedy, the scenario of the
Commedia dell’arte titled Il cavaliere dai tre gigli d’oro
