Cell Type-Specific Optogenetic Dissection of Brain Rhythms. Trends Neurosci. 2018 Mar;41(3):122-124 Authors: Adesnik H Abstract A pair of 2009 papers by Cardin et al. and Sohal et al. marked a watershed moment as optogenetics exploded onto the scene of systems neuroscience. This pair of back-to-back papers in the June issue of Nature leveraged a powerful […]
Visible light reduces C. elegans longevity. Nat Commun. 2018 Mar 02;9(1):927 Authors: De Magalhaes Filho CD, Henriquez B, Seah NE, Evans RM, Lapierre LR, Dillin A Abstract The transparent nematode Caenorhabditis elegans can sense UV and blue-violet light to alter behavior. Because high-dose UV and blue-violet light are not a common feature outside of the […]
Evidence for a neural law of effect. Science. 2018 03 02;359(6379):1024-1029 Authors: Athalye VR, Santos FJ, Carmena JM, Costa RM Abstract Thorndike’s law of effect states that actions that lead to reinforcements tend to be repeated more often. Accordingly, neural activity patterns leading to reinforcement are also reentered more frequently. Reinforcement relies on dopaminergic activity […]
Recent cross-modal statistical learning influences visual perceptual selection. J Vis. 2018 Mar 01;18(3):1 Authors: Piazza EA, Denison RN, Silver MA Abstract Incoming sensory signals are often ambiguous and consistent with multiple perceptual interpretations. Information from one sensory modality can help to resolve ambiguity in another modality, but the mechanisms by which multisensory associations come to […]
Related Articles Characteristics of Implicit Sensorimotor Adaptation Revealed by Task-irrelevant Clamped Feedback. J Cogn Neurosci. 2017 Jun;29(6):1061-1074 Authors: Morehead JR, Taylor JA, Parvin DE, Ivry RB Abstract Sensorimotor adaptation occurs when there is a discrepancy between the expected and actual sensory consequences of a movement. This learning can be precisely measured, but its source has […]
Neuroplasticity of language in left-hemisphere stroke: Evidence linking subsecond electrophysiology and structural connections.
Related Articles Neuroplasticity of language in left-hemisphere stroke: Evidence linking subsecond electrophysiology and structural connections. Hum Brain Mapp. 2017 Jun;38(6):3151-3162 Authors: Piai V, Meyer L, Dronkers NF, Knight RT Abstract The understanding of neuroplasticity following stroke is predominantly based on neuroimaging measures that cannot address the subsecond neurodynamics of impaired language processing. We combined behavioral […]

Neuroimage. 2017 Apr 01;149:98-113 Authors: Cronin MJ, Wang N, Decker KS, Wei H, Zhu WZ, Liu C Abstract Quantitative susceptibility mapping (QSM) is increasingly used to measure variation in tissue composition both in the brain and in […]
Heteromeric KV2/KV8.2 channels mediate delayed rectifier potassium currents in primate photoreceptors.
Related Articles Heteromeric KV2/KV8.2 channels mediate delayed rectifier potassium currents in primate photoreceptors. J Neurosci. 2018 Feb 24;: Authors: Gayet-Primo J, Yaeger DB, Khanjian RA, Puthussery T Abstract Silent voltage-gated potassium channel subunits (KVS) interact selectively with members of the KV2 channel family to modify their functional properties. The localization and functional roles of these […]
