Mountain excitement
theory? What is its legacy today in biology? Quite a few mathematical fads have burst onto the popular press, promising great new insights into biology: information theory, catastrophe theory, chaos theory, and most recently complexity theory, to name just a few. All were quite useful in their founding fields (except complexity, which has proven slippery to even define), but all failed to live ...
متن کاملThe excitement of discovery.
I had the good luck to start research at the dawn of molecular biology when it was possible to ask fundamental questions about the nature of the nucleic acids and how information is transferred in living systems. The search for answers led me into many different areas, often with the question of how molecular structure leads to biological function. Early work in this period provided some of the...
متن کاملGABA Generates Excitement
In the CNS, gamma-aminobutyric acid (GABA) acts as an inhibitory transmitter via ligand-gated GABA(A) receptor channels and G protein-coupled GABA(B) receptors. Both of these receptor types mediate inhibitory postsynaptic transmission throughout the nervous system. For GABA(A) receptors, this inhibitory action is associated with a hyperpolarization due to an increase in conductance to chloride ...
متن کاملRetrograde Signaling Causes Excitement
Retrograde signaling is a powerful tool to shape synaptic transmission, typically inducing inhibition of transmitter release. A new study published in this issue of Neuron by Carta et al. (2014) now provides strong support for arachidonic acid as a potentiating retrograde messenger.
متن کاملSlowly Building Excitement
While some neurons are tuned to integrate fast and precisely timed inputs, others set behavioral states on much slower timescales. In this issue of Cell, Branco et al. demonstrate that body weight is regulated by hypothalamic neurons using a highly effective form of slow synaptic integration, which is mediated by the voltage gated sodium channel Nav1.7.
