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 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.
متن کاملVisual acuity and excitement.
Viewed within the framework of activation theory, individuals with low visual acuity might conceivably be seen as persons with low preferred levels of activation who seek to reduce stimulus input in order to maintain activation at their preferred level. It was hypothesized, therefore, that persons with low visual acuity would demonstrate less receptivity to environmental stimulation than highac...
