This essay deals with two retellings of Genesis: Thomas Mann's "Joseph and his brothers" and Anita Diamant's "The red tent". Both authors note the presence of implicit pagan tendencies among the women of Jacob's clan (Gen 31:19; 35:2) and develop this subtext for their respective ideological purposes. Thomas Mann creates a dichotomy between the backwardness of the pagan female realm and the progressive nature of the monotheistically-oriented patriarchs. The path toward modern humanist values comes from the likes of Jacob and Joseph rather than Rachel and Leah in Mann's novel. Anita Diamant, on the other hand, adopts the opposite attitude, namely, that the paganism of Rachel, Leah, as well as other women in Jacob's family, is a humane and natural form of spirituality in contrast to the bloodthirsty Yahwism of Jacob and his sons. The latter point is illustrated by the sacking of Shechem. In order to question the patriarchal stance of the Old Testament Diamant reverses the key values informing the theology of the Bible. Thus, in "The red tent" Jacob's wives venerate the Ashera in particular. The latter constitutes a challenge to the stance of the Deuteronomic History where the cult of the Ashera is viewed as a key reason behind God's decision to let the Babylonians destroy the Southern Kingdom of Judah. And since Mann's novel upholds the patriarchal spirit of the biblical text, Diamant enters into debate with the continuity of female disempowerment which reaches all the way from Genesis to "Joseph and his brothers".
Background The synchrony hypothesis postulates that precise temporal synchronization of different pools of neurons conveys information that is not contained in their firing rates. The synchrony hypothesis had been supported by experimental findings demonstrating that millisecond precise synchrony of neuronal oscillations across well separated brain regions plays an essential role in visual perception and other higher cognitive tasks [1]. Albeit, more evidence is being accumulated in favour of its role as a binding mechanism of distributed neural responses, the physical and anatomical substrate for such a dynamic and precise synchrony, especially zero-lag even in the presence of non-negligible delays, remains unclear. Here we propose a simple network motif that naturally accounts for zero-lag synchronization for a wide range of temporal delays [3]. We demonstrate that zero-lag synchronization between two distant neurons or neural populations can be achieved by relaying the dynamics via a third mediating single neuron or population. Methods We simulated the dynamics of two Hodgkin-Huxley neurons that interact with each other via an intermediate third neuron. The synaptic coupling was mediated through alpha-functions. Individual temporal delays of the arrival of pre-synaptic potentials were modelled by a gamma distribution. The strength of the synchronization and the phase-difference between each individual pairs were derived by cross-correlation of the membrane potentials. Results In the regular spiking regime the two outer neurons consistently synchronize with zero phase lag irrespective of the initial conditions. This robust zero-lag synchronization naturally arises as a consequence of the relay and redistribution of the dynamics performed by the central neuron. This result is independent on whether the coupling is excitatory or inhibitory and can be maintained for arbitrarily long time delays (see Fig. 1). Conclusion We have presented a simple and extremely robust network motif able to account for the isochronous synchronization of distant neural elements in a natural way. As opposed to other possible mechanisms of neural synchronization, neither inhibitory coupling, gap junctions nor precise tuning of morphological parameters are required to obtain zero-lag synchronized neuronal oscillation.
