    Caffeine Functions by Inhibiting Dorsal and Ventral Hippocampal Adenosine 2A Receptors to Modulate Memory and Anxiety, Respectively by Yawei Xu, Yalei Ning, Yan Zhao, Yan Peng, Fen Luo, Yuanguo Zhou, Ping Li

    Published 2022-02-01
    “…These results, together with the enhanced memory of dorsal hippocampus A2AR knockout mice and greater anxiety-like behavior of ventral hippocampus A2AR knockout mice without caffeine, indicates a dissociation between the roles of ventral and dorsal hippocampal A2A receptors in caffeine’s effects on anxiety-like and memory-related behavioral measures, respectively. Furthermore, optogenetic activation of dorsal or ventral hippocampal A2ARs reversed the behavioral alterations caused by drinking caffeine, leading to impaired memory or decreased anxiety-like behaviors, respectively. …”

    Visualization of oxytocin release that mediates paired pulse facilitation in hypothalamic pathways to brainstem autonomic neurons. by Ramón A Piñol, Heather Jameson, Anastas Popratiloff, Norman H Lee, David Mendelowitz

    Published 2014-01-01
    “…In this study, using rats, we directly show, using sniffer CHO cells that express oxytocin receptors and the Ca2+ indicator R-GECO, that optogenetic activation of channelrhodopsin-2 (ChR2) expressing PVN fibers in the brainstem activates oxytocin receptors in the dorsomotor nucleus of the vagus (DMNV). …”

    Identification of a Group of GABAergic Neurons in the Dorsomedial Area of the Locus Coeruleus. by Xin Jin, Shanshan Li, Brian Bondy, Weiwei Zhong, Max F Oginsky, Yang Wu, Christopher M Johnson, Shuang Zhang, Ningren Cui, Chun Jiang

    Published 2016-01-01
    “…Although GABA is the major inhibitory neurotransmitter of LC neurons, the modulation of LC neuronal firing activity by local GABAergic interneurons remains poorly understood with respect to their precise location, intrinsic membrane properties and synaptic modulation. Here, we took an optogenetic approach to address these questions. Channelrhodopsin (ChR2) in a tandem with the yellow fluorescent protein (YFP) was expressed in GABAergic neurons under the control of glutamic acid decarboxylase 2 (GAD2) promoter. …”

    NMDA receptor activation induces long-term potentiation of glycine synapses. by Michelle L Kloc, Bruno Pradier, Anda M Chirila, Julie A Kauer

    Published 2019-01-01
    “…Repetitive depolarization alone of the postsynaptic GABAergic neuron also potentiated glycinergic synapses, and intracellular EGTA prevented both NMDA-induced and depolarization-induced potentiation of glycinergic IPSCs.

    A locomotor neural circuit persists and functions similarly in larvae and adult Drosophila by Kristen Lee, Chris Q Doe

    Published 2021-07-01
    “…MDN-Pair1 connectivity is lost during early pupal stages, when both neurons are severely pruned back, but connectivity is re-established at mid-pupal stages and persist into the adult. In the adult, optogenetic activation of Pair1 resulted in arrest of forward locomotion, similar to what is observed in larvae. …”

    Dopamine Neurons Mediate Learning and Forgetting through Bidirectional Modulation of a Memory Trace by Jacob A. Berry, Anna Phan, Ronald L. Davis

    Published 2018-10-01
    “…Conditioning with a second odor restores the responses of MBOn-γ2α′1 to a previously learned odor while depressing responses to the newly learned odor, showing that learning and forgetting can occur simultaneously. Moreover, optogenetic activation of DAn-γ2α′1 is sufficient for the bidirectional modulation of MBOn-γ2α′1 response properties. …”

    Phasic and Tonic Locus Coeruleus Stimulation Associated Valence Learning Engages Distinct Adrenoceptors in the Rat Basolateral Amygdala by Tamunotonye Omoluabi, Kyron D. Power, Tayebeh Sepahvand, Qi Yuan

    Published 2022-05-01
    “…Here, we ask if phasic and tonic LC activation-associated valence learning requires different adrenoceptors in the BLA, in comparison with the odor valence learning induced by natural reward and aversive conditioning. Using optogenetic activation of the LC and local drug infusions in the BLA, we show that phasic LC activation-induced positive odor valence learning is dependent on both α1 and β-adrenoceptors, whereas tonic LC activation induced-negative odor valence learning depends on β-adrenoceptors only. …”
