Revisiting the left ear advantage for phonetic cues to talker identification.

Previous research suggests that learning to use a phonetic property [e.g., voice-onset-time, (VOT)] for talker identity supports a left ear processing advantage.

Functional characterization and high-throughput screening of positive allosteric modulators of α7 nicotinic acetylcholine receptors in IMR-32 neuroblastoma cells.

α7 nicotinic acetylcholine receptors (nAChRs) are characterized by relatively low ACh sensitivity, rapid activation, and fast desensitization kinetics. ACh/agonist evoked currents at the α7 nAChR are transient, and, typically, calcium flux responses are difficult to detect using conventional fluorometric assay techniques. One approach to study interactions of agonists with the α7 nAChR is by utilizing positive allosteric modulators (PAMs).
