Benny Chain: The T cell receptor repertoire in health and disease

Benny Chain: The T cell receptor repertoire in health and disease

The human adaptive immune system makes robust decisions which regulate quantitative and qualitative parameters of a complex physiological system, to prevent invasion and destruction of tissues by the enormous array of microorganisms which share our environment. Remarkably, these decisions are made by a distributed system made up of moving parts...

Optical reporters of neural activity have improved dramatically over the past decade. Recent developments in optical imaging approaches have unlocked the power of these indicators and can now provide real-time read-outs from large populations of brain cells in a wide range of living organisms.

Early embryogenesis of most metazoans is characterized by rapid and synchronous cleavage divisions. After fertilization, Drosophila embryos undergo 13 swift rounds of DNA replication and mitosis without cytokinesis, resulting in a multinucleated syncytium containing about 6,000 nuclei.

Markus Meister: Large Ratios in Brain Science

Markus Meister: Large Ratios in Brain Science
Mon, Apr 15, 2019, 12:00 pm

In physics and engineering dimensionless numbers frequently help to characterize the state of a system. I will present a series of vignettes about unusually large dimensionless numbers that arise in brain science. These can indicate issues that are poorly understood, and in some cases clearly misunderstood.
