Distribution of Tetrodotoxin in Pacific Oysters (Crassostrea gigas)
Marine Drugs, 2021 A potent and heat-stable tetrodotoxin (TTX) has been found to accumulate in various marine bivalve species, including Pacific oysters (Crassostrea gigas), raising a food safety concern.

Cell biological mechanisms of activity-dependent synapse to nucleus translocation of CRTC1 in neurons. [PDF]
, 2015 Previous studies have revealed a critical role for CREB-regulated transcriptional coactivator (CRTC1) in regulating neuronal gene expression during learning and memory. CRTC1 localizes to synapses but undergoes activity-dependent nuclear translocation to

The skin microbiome facilitates adaptive tetrodotoxin production in poisonous newts
eLife, 2020 Rough-skinned newts (Taricha granulosa) use tetrodotoxin (TTX) to block voltage-gated sodium (Nav) channels as a chemical defense against predation.

A sensorimotor area (NIf) is required for the production of learned vocalizations [PDF]
, 2011 Sensory feedback is essential for the acquisition of complex motor behaviors, including birdsong. In zebra finches, auditory feedback is relayed to the descending motor pathway primarily through the nucleus interfacialis nidopalii (NIf).

Na(V)1.5 sodium channel window currents contribute to spontaneous firing in olfactory sensory neurons [PDF]
, 2014 Olfactory sensory neurons (OSNs) fire spontaneously as well as in response to odor; both forms of firing are physiologically important. We studied voltage-gated Na+ channels in OSNs to assess their role in spontaneous activity.

Effects of cromakalim (BRL 34915) on potassium conductances in CA3 neurons of the guinea-pig hippocampus in vitro [PDF]
, 1989 The action of the potassium channel activator, cromakalim (BRL 34915), on membrane potential, input resistance and current-voltage-relationship of CA3 neurons in a slice preparation of the guinea-pig hippocampus was investigated by means of intracellular
