GABA
- Distinctive mechanisms underlie the emission of social electric signals of submission in Gymnotus omarorum
Summary: The modulation of the excitability of neurons of the electromotor command nucleus emerges as a novel cellular mechanism expanding the repertoire of electric communication signals in freshwater weakly electric fish.
- Taurine activates glycine and GABAA receptor currents in anoxia-tolerant painted turtle pyramidal neurons
Summary: Taurine increases naturally in anoxic painted turtle brain and can activate both GABA and glycine receptors, which probably contributes to the mechanism of anoxia tolerance.
- Physiological responses of ionotropic histamine receptors, PxHCLA and PxHCLB, to neurotransmitter candidates in a butterfly, Papilio xuthus
Summary: Identification and characterization of two histamine-gated chloride channels in the visual system of Papilio; both channels respond to histamine as well as to GABA.
- Acid–base physiology, neurobiology and behaviour in relation to CO2-induced ocean acidification
Summary: This article reviews basic acid–base regulatory and neurobiology mechanisms relevant for behavioural alteration in fish exposed to CO2-induced seawater acidification, and identifies areas for future research.
- Mechanistic underpinnings of dehydration stress in the American dog tick revealed through RNA-Seq and metabolomics
Highlighted Article: Ticks employ a suite of molecular and biochemical mechanisms to survive dehydration stress; strategies include limiting damage and maximizing recovery when conditions allow.
- Serotonin, but not dopamine, controls the stress response and anxiety-like behavior in the crayfish Procambarus clarkii
Summary: After stress, crayfish brain 5-HT levels increase, which induces anxiety-like behavior (ALB) but the level of dopamine does not change, and in contrast to 5-HT, injection of dopamine does not trigger a metabolic response or ALB.
