Energy limitation as a selective pressure on the evolution of sensory systems
JE Niven, SB Laughlin - Journal of Experimental Biology, 2008 - journals.biologists.com
… The Shaker conductance incurs an energetic cost at rest, but not at more depolarized
potentials when it is inactivated(Niven et al., 2003a; Niven et al., 2003b). In Drosophila mutant …

Conserved regulation of cardiac calcium uptake by peptides encoded in small open reading frames
Small open reading frames (smORFs) are short DNA sequences that are able to encode
small peptides of less than 100 amino acids. Study of these elements has been neglected …

Why do axons differ in caliber?
CNS axons differ in diameter (d) by nearly 100-fold (∼0.1–10 μm); therefore, they differ in
cross-sectional area (d 2 ) and volume by nearly 10,000-fold. If, as found for optic nerve, …

[HTML][HTML] Action potential energy efficiency varies among neuron types in vertebrates and invertebrates
The initiation and propagation of action potentials (APs) places high demands on the
energetic resources of neural tissue. Each AP forces ATP-driven ion pumps to work harder to …

[HTML][HTML] Fly photoreceptors demonstrate energy-information trade-offs in neural coding
JE Niven, JC Anderson, SB Laughlin - PLoS biology, 2007 - journals.plos.org
Trade-offs between energy consumption and neuronal performance must shape the design
and evolution of nervous systems, but we lack empirical data showing how neuronal energy …

Do insect metabolic rates at rest and during flight scale with body mass?
JE Niven, JPW Scharlemann - Biology Letters, 2005 - royalsocietypublishing.org
Energetically costly behaviours, such as flight, push physiological systems to their limits
requiring metabolic rates (MR) that are highly elevated above the resting MR (RMR). Both RMR …

[PDF][PDF] Mushroom bodies are required for learned visual navigation, but not for innate visual behavior, in ants
Visual navigation in ants has long been a focus of experimental study [1–3], but only recently
have explicit hypotheses about the underlying neural circuitry been proposed [4]. Indirect …

[PDF][PDF] Miniaturization of nervous systems and neurons
Miniaturized species have evolved in many animal lineages, including insects and vertebrates.
Consequently, their nervous systems are constrained to fit within tiny volumes. These …
