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

…, JI Pueyo, FMG Pearl, MA Cespedes, JE Niven… - Science, 2013 - science.org
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?

JA Perge, JE Niven, E Mugnaini… - Journal of …, 2012 - Soc Neuroscience
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

…, M Stemmler, SB Laughlin, JE Niven - PLoS computational …, 2010 - journals.plos.org
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 …

[HTML][HTML] Understanding the mental health of doctoral researchers: a mixed methods systematic review with meta-analysis and meta-synthesis

…, L Chapman, SF Valeix, P Roberts, JE Niven… - Systematic reviews, 2020 - Springer
Background Data from studies with undergraduate and postgraduate taught students
suggest that they are at an increased risk of having mental health problems, compared to the …

[PDF][PDF] Mushroom bodies are required for learned visual navigation, but not for innate visual behavior, in ants

…, B Wozniak, R Goulard, B Webb, P Graham, JE Niven - Current Biology, 2020 - cell.com
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 …

Neuronal energy consumption: biophysics, efficiency and evolution

JE Niven - Current opinion in neurobiology, 2016 - Elsevier
Highlights • Electrical signaling consumes substantial amounts of energy influencing physiology
and anatomy. • Action potential energy consumption depends on the voltage-gated ion …

[PDF][PDF] Miniaturization of nervous systems and neurons

JE Niven, SM Farris - Current Biology, 2012 - cell.com
Miniaturized species have evolved in many animal lineages, including insects and vertebrates.
Consequently, their nervous systems are constrained to fit within tiny volumes. These …
