Independence of landmark and self-motion-guided navigation: a different role for grid cells

Feb 5, 2014 - Recent interest in the neural bases of spatial navigation stems from the discovery of neuronal populations with strong, specific spatial signals. The regular firing field arrays of medial entorhinal grid cells suggest that they may provide place

Interspecies comparison of sea star adhesive proteins

Oct 28, 2019 - Sea stars use adhesive secretions to attach their numerous tube feet strongly and temporarily to diverse surfaces. After detachment of the tube feet, the adhesive material stays bound to the substrate as so-called ‘footprints’. In the common sea

Smooth muscle contractility causes the gut to grow anisotropically

Oct 31, 2019 - The intestine is the most anisotropically shaped organ, but, when grown in culture, embryonic intestinal stem cells form star- or sphere-shaped organoids. Here, we present evidence that spontaneous tonic and phasic contractions of the circular

The induction and inhibition of differentiation in normal and leukaemic cells

Mar 12, 1990 - For granulocytic-macrophage progenitor populations and their progeny, five glycoproteins have been identified: GM-CSF, G-CSF, multi-CSF, M-CSF and IL-6 that can regulate their proliferative activity, maturation and functional activities. The same

The Leeuwenhoek Lecture, 1978 Bacteria as proper subjects for cancer research

Jun 24, 1980 - Cancers are clones of abnormal cells, arising presumably as the result of mutational or epigenetic alterations of gene expression. The kinetics of appearance of spontaneous cancers in populations of multiplying cells (i. e. the relation between age
