Evaluation of the pollution pressures posed by groups of chemicals on British riverine invertebrate populations. [PDF]

open access: yesBiol Rev Camb Philos Soc
ABSTRACT Globally, rivers receive a diverse range of chemicals, including metals, pesticides, persistent organic pollutants, petrochemicals, human and veterinary pharmaceuticals and personal care products. However, the extent to which these different chemical groups affect riverine invertebrate communities is not well defined.

Memory-enhancing effects of short-term fasting

open access: yesThe European Zoological Journal, 2020
Many recent reports describe memory-enhancing effects of short-term fasting, but the underlying mechanisms are unknown. In the present study, we demonstrate that the insulin increase occurring during short-term fasting is a key factor in forming the ...

Multi-neuronal refractory period adapts centrally generated behaviour to reward [PDF]

open access: yes, 2012
Oscillating neuronal circuits, known as central pattern generators (CPGs), are responsible for generating rhythmic behaviours such as walking, breathing and chewing.

Associative memory stored by functional novel pathway rather than modifications of preexisting neuronal pathways [PDF]

open access: yes, 2006
Associative conditioning involves changes in the processing pathways activated by sensory information to link the conditioned stimulus (CS) to the conditioned behavior.

Reversal of age-related learning deficiency by the vertebrate PACAP and IGF-1 in a novel invertebrate model of aging: the pond snail (Lymnaea Stagnalis) [PDF]

open access: yes, 2014
With the increase of life span, nonpathological age-related memory decline is affecting an increasing number of people. However, there is evidence that age-associated memory impairment only suspends, rather than irreversibly extinguishes, the intrinsic ...

Multiple types of control by identified interneurons in a sensory-activated rhythmic motor pattern. [PDF]

open access: yes, 2001
Modulatory interneurons that can drive central pattern generators (CPGs) are considered as good candidates for decision-making roles in rhythmic behaviors.

A homolog of the vertebrate pituitary adenylate cyclase-activating polypeptide is both necessary and instructive for the rapid formation of associative memory in an invertebrate [PDF]

open access: yes, 2010
Similar to other invertebrate and vertebrate animals, cAMP dependent signaling cascades are key components of long-term memory (LTM) formation in the snail Lymnaea stagnalis, an established experimental model for studying evolutionarily conserved ...

The pond snail Lymnaea stagnalis [PDF]

open access: yesEvoDevo, 2020
AbstractThe freshwater snail Lymnaea stagnalis has a long research history, but only relatively recently has it emerged as an attractive model organism to study molecular mechanisms in the areas of developmental biology and translational medicine such as learning/memory and neurodegenerative diseases.
