Apoptosis and Neurogenesis in DRASiW-like Systems
Massimo De Gregorio, Istituto di Cibernetica “Eduardo Caianiello” – CNR, Pozzuoli – Italy

Abstract
Neuronal death (apoptosis) and neurogenesis in mammal adult brains, indicates that neuronal turnover could be considered as a special form of neuroplasticity mostly related to memory, cognition and neurodegenerative disorders. This work introduces apoptotic and neurogenic events in DRASiW–like systems (a particular model of weightless neural systems). The results obtained and their possible implications have not to be seen in the light of proposing a new neural model for future biological simulation, but rather as the discovery of new characteristics and potentialities of weightless neural systems.
We have shown that apoptosis and neurogenesis in DRASiW systems respectively slightly affect or does not affect the performance of the original system. In order to verify this characteristic, we selected four very different (in terms of data representation) Data Sets. The four DRASiW systems shown the same behavior with respect to the generation of "mental” images and measures (what we called system functionalities).

Biosketch
Massimo De Gregorio was born in Torre del Greco (Naples - Italy) in 1962. Upon completion of his graduate education (Laurea in Fisica - Cibernetica) at the University of Naples), in the 1994 he began working as researcher at the Istituto di Cibernetica “Eduardo Caianiello” of Consiglio Nazionale delle Ricerche (CNR) in the Research Group “Theory and Techniques of Knowledge Representation”. Between 1999 and 2003, he held visiting teaching positions at University of Naples “Federico II” (2000-2003) and Second University of Naples (1999-2000). His research work has been mainly concerned with Artificial Intelligence, Artificial Neural Networks (in particular Weightless Neural Systems), Neuro-Symbolic Hybrid Systems, with extensive applications in Expert Systems, Pattern Recognition, Active Video Surveillance and more recently in Behaviour Based Robotics. He is co-author of different invited papers of several international conferences on Artificial Intelligence and Artificial Neural Networks.
