Whole-transcriptome changes in gene expression accompany aging of sensory neurons in Aplysia californica

open access: yesBMC Genomics, 2018
Background Large-scale molecular changes occur during aging and have many downstream consequences on whole-organism function, such as motor function, learning, and memory.

A Single Central Pattern Generator for the Control of a Locomotor Rolling Wave in Mollusc Aplysia

open access: yesResearch, 2023
Locomotion in mollusc Aplysia is implemented by a pedal rolling wave, a type of axial locomotion. Well-studied examples of axial locomotion (pedal waves in Drosophila larvae and body waves in leech, lamprey, and fish) are generated in a segmented nervous

Aplysia synaptosomes. II. Release of transmitters [PDF]

open access: yesThe Journal of Neuroscience, 1989
A subcellular fraction (P3) from Aplysia is enriched in synaptosomes (Chin et al., 1988) and is capable of accumulating 5-HT and choline. At an external 3H-5-HT concentration of 1.8 microM, the P3 fraction took up 0.12 nmol/mg protein in 30 min. Uptake was dependent on external Na+.

Parameter investigation for urban surface‐energy balance: A large‐eddy simulation study

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Large eddy simulation modelling is used to investigate the variation in surface‐energy balance (SEB) across an ensemble of morphometrically identical urban geometries. The geometries have the same plan‐area fraction, vegetated fraction, and frontal‐area index, but are unique in terms of building and green‐space layout.

Caged calcium in Aplysia pacemaker neurons. Characterization of calcium-activated potassium and nonspecific cation currents. [PDF]

open access: yes, 1989
We have studied calcium-activated potassium current, IK(Ca), and calcium-activated nonspecific cation current, INS(Ca), in Aplysia bursting pacemaker neurons, using photolysis of a calcium chelator (nitr-5 or nitr-7) to release caged calcium ...

Collaborative Sampling and Imaging of Phytoplankton Communities by Two Long‐Range Autonomous Underwater Vehicles Using Acoustic Tracking and Messaging

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Collaborative operation of multiple autonomous underwater vehicles (AUVs) can effectively achieve scientific goals that are hard to achieve by independently operated vehicles. Some science payloads are large, expensive, and need to be installed in the vehicle's nose cone. A vehicle can only carry one such payload.

Characterization of the role of eIF4G in stimulating cap- and IRES-dependent translation in aplysia neurons. [PDF]

open access: yesPLoS ONE, 2013
The rate-limiting step(s) of translation in the nervous system have not been clearly identified. We have been examining this question in the cell body of the Aplysia sensory neuron, where translational regulation is important for the regulation of ...

William James and the Evolution of Consciousness [PDF]

open access: yes, 1999
Despite having been relegated to the realm of superstition during the dominant years of behaviourism, the investigation and discussion of consciousness has again become scientifically defensible.

Integrative phylogenomics and morphology reveal the evolution and biogeography of Encephalartos (Zamiaceae)

open access: yesJournal of Systematics and Evolution, EarlyView.
We aimed to conduct phylogenetic analyses of Encephalartos, a cycad genus endemic to Africa, using 3545 single‐copy nuclear genes extracted from transcriptome data, covering 64/65 of the recognized species, along with inference of divergence times using two secondary calibration points.

Nociceptive Biology of Molluscs and Arthropods: Evolutionary Clues About Functions and Mechanisms Potentially Related to Pain

open access: yesFrontiers in Physiology, 2018
Important insights into the selection pressures and core molecular modules contributing to the evolution of pain-related processes have come from studies of nociceptive systems in several molluscan and arthropod species.
