Biased Competition during Long-term Memory Formation
A key task for the brain is to determine which pieces of information are worth storing in memory. To build a more complete representation of the environment, memory systems may prioritize new information that has not already been stored. Here, we propose a mechanism that supports this preferential encoding of new information, whereby prior experience attenuates neural activity for old informati...
متن کاملTeam formation and biased self-attribution
There exists extensive evidence that people learn positively about themselves. We build on this finding to develop a model of team formation in the workplace. We show that learning positively about oneself systematically undermines the formation of teams. Agents becoming overconfident tend to ask for an excessive share of the group outcome. Positive learning generates divergence in workers' bel...
متن کاملLink Biased Strategies in Network Formation Games
We show a simple method for constructing an infinite family of graph formation games with link bias so that the resulting games admits, as a pairwise stable solution, a graph with an arbitrarily specified degree distribution. Pairwise stability is used as the equilibrium condition over the more commonly used Nash equilibrium to prevent the occurrence of ill-behaved equilibrium strategies that d...
متن کاملCooperative mechanisms of mitotic spindle formation.
Cooperativity is well known to promote the speed of some biochemical reactions by accelerating the activity of enzymes. Recent studies have shown that cooperative interactions also function during the formation of a complex cellular structure, the mitotic spindle. Capture of kinetochores by dynamic astral microtubules was originally proposed as the basis of spindle formation. However, mounting ...
متن کاملBipolar meiotic spindle formation without chromatin
Establishing a bipolar spindle is an early event of mitosis or meiosis. In somatic cells, the bipolarity of the spindle is predetermined by the presence of two centrosomes in prophase. Interactions between the microtubules nucleated by centrosomes and the chromosomal kinetochores enable the formation of the spindle. Non-specific chromatin is sufficient, however, to promote spindle assembly in X...
