Facilitation of cortico-amygdala synapses by nicotine: activity-dependent modulation of glutamatergic transmission.
Article in Journal of neurophysiology, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 36 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The basolateral nucleus of the amygdala (BLA) receives cholinergic innervation from the basal forebrain and nicotine, via activation of neuronal nicotinic acetylcholine receptors (nAChRs), can improve performance in amygdala-based learning tasks. We tested the hypothesis that acute and prenatal nicotine exposure modulates cortico-amygdala synaptic transmission. We found that low-dose, single-trial exposures to nicotine can elicit lasting facilitation, the extent of which is dependent on the level of stimulation of the cortical inputs to the BLA. In addition, sustained facilitation is ablated by prenatal exposure to nicotine. This study examined synaptic transmission in 238 patch-clamp recordings from BLA neurons in acute slice from mouse brain. Pharmacological studies in wild-type and nAChR subunit knock-out mice reveal that activation of presynaptic alpha 7, containing (alpha 7*) and non-alpha 7* nAChRs, facilitates glutamatergic transmission in an activity-dependent manner. Without prior stimulation, application of nicotine elicits modest and transient facilitation of glutamatergic postsynaptic currents (PSCs) in about 40% of BLA neurons. With low-frequency stimulation of cortical inputs nicotine elicits robust facilitation of transmission at about 60% of cortico-BLA synapses and synaptic strength remains elevated at about 40% of these connections for >15 min after nicotine washout. Following paired-pulse stimulation nicotine elicits long-lasting facilitation of glutamatergic transmission at about 70% of cortico-BLA connections. Nicotine reduces the threshold for activation of long-term potentiation of cortico-BLA synapses evoked by patterned stimulation. Prenatal exposure to nicotine reduced subsequent modulatory responses to acute nicotine application.
