Molecular mechanisms of ovulation: co-ordination through the cumulus complex.
Successful ovulation requires that developmentally competent oocytes are released with appropriate timing from the ovarian follicle. Somatic cells of the follicle sense the ovulatory stimulus and guide resumption of meiosis and release of the oocyte, as well as structural remodelling and luteinization of the follicle. Complex intercellular communication co-ordinates critical stages of oocyte ma...
متن کامل'Feeling' the flow of time through sensorimotor co-ordination
In this paper, we aim to design decision-making mechanisms for a simulated Khepera robot equipped with simple sensors, which integrates over time its perceptual experience in order to initiate a simple signalling response. Contrary to other previous similar studies, in this work the decision-making is uniquely controlled by the time-dependent structures of the agent controller, which in turn ar...
متن کاملCell-to-cell communication and ovulation. A study of the cumulus-oocyte complex
Cell-to-cell communication was characterized in cumulus-oocyte complexes from rat ovarian follicles before and after ovulation. Numerous, small gap junctional contacts were present between cumulus cells and oocytes before ovulation. The gap junction are formed on the oocyte surface by cumulus cell processes that transverse the zona pellucida and contact the oolemma. The entire cumulus mass was ...
متن کاملIndependence and Co-ordination –
* The views expressed in this paper are personal. Most outsiders tend to base their analysis of the future of the Eurosystem on the shape of the Federal Reserve System in the US. This paper argues that the US model is inappropriate. It suggests that the Eurosystem is pursuing a different arrangement, where the balance of power in the national central banks rather than in the centre may continue...
متن کاملDistributed Agenda Management through Decentralised Vowels Co-ordination Approach
In this paper we present an application to a Distributed Agenda Management problem through a decentralised multi-agent coordination model. Each agent represents a user's personal agenda, which must to co-ordinate with other agendas in order to reach a joint commitment, such as a meeting scheduling, respecting user privacy and local constraints. Constraints represent personal preferences and com...
