A fundamental quest in Neuroscience research is to reveal the function(s) of single neurons and networks. Understanding function seems to be on relatively solid grounds at the periphery where both anatomy and physiology converge in a simplified manner. However, as one ascends higher into the central nervous system, anatomy and physiology become increasingly more complex and functions become diffic ...

“JudgingHistories” sets out to examine the epistemic premises innate to universalizing historical experience, by scrutinizing the quest for historical understanding and moral judgment against the backdrop of an emerging global cultural environment, fraught with multiple recollections, while using memories of World War II as the empirical core of the study. The pivotal constellation of research eme ...

Understanding immune evasion by malaria parasites (MALMASQ)

Date du début: 1 juin 2014, Date de fin: 31 mai 2019,

"The deadliest form of human malaria is caused by the protozoan parasite, Plasmodium falciparum, which annually infects millions worldwide. Its virulence is attributed to its ability to evade the human immune system, by modifying the host red blood cell surface to adhere to the vascular endothelium and to undergo antigenic variation. Antigenic variation is achieved through switches in expression o ...

This proposal proceeds from an anomaly. Apartheid routinely breached the separation that it names. Whereas the South African regime was deeply isolationist in international terms, new research links it to the Cold War and decolonization. Yet this trend does not consider sufficiently that the global contest over the meaning of apartheid and resistance to it occurs on the terrain of culture. My proj ...

New Concepts in Bacterial Response to their Surroundings (BACTERIAL RESPONSE)

Date du début: 1 avr. 2014, Date de fin: 31 mars 2019,

Bacteria in nature exhibit remarkable capacity to sense their surroundings and rapidly adapt to diverse conditions by gaining new beneficial traits. This extraordinary feature facilitates their survival when facing extreme environments. Utilizing Bacillus subtilis as our primary model organism, we propose to study two facets of this vital bacterial attribute: communication via extracellular nanotu ...

Model theory deals with general classes of structures (called models).Specific examples of such classes are: the class of rings or the class ofalgebraically closed fields.It turns out that counting the so-called complete types over models in theclass has an important role in the development of model theory in general andstability theory in particular.Stable classes are those with relatively few co ...

International Integration and Social Identity: Theory and Evidence (INTEGRATION)

Date du début: 1 mars 2014, Date de fin: 28 févr. 2019,

Understanding economic and political integration has long been a central concern for economists. An important missing ingredient in the existing literature is the analysis of endogenously determined social identity. By “social identity” I refer to the fact that individuals often care deeply about the groups to which they belong. By “endogenously determined” I refer to the fact that individuals do ...

Understanding Auditory Information Processing in Naturalistic Environments (RATLAND)

Date du début: 1 févr. 2014, Date de fin: 31 janv. 2019,

Studies of sensory processing in awake mammals are often limited to simple perceptual decisions, such as detecting the differences between two similar stimuli. However, such sensory tasks are usually limited by peripheral information, and do not tap into the special processing capabilities of the cortex. I hypothesize that neuronal responses in auditory cortex represent ethologically-relevant quan ...

ChIs respond to novel stimuli with a burst-pause (B-P) in their tonic firing. The B-P response is a neural correlate of classical conditioning, and as such shows a large degree of plasticity in response to behavioral conti ...
