NMDA Receptor Contributions to Visual Contrast Coding

Michael B. Manookin, Michael Weick, Benjamin K. Stafford, Jonathan B. Demb. In the retina, it is not well understood how visual processing depends on AMPA- and NMDA-type glutamate receptors. Here we investigated how these receptors contribute to contra… . . . → Read More: NMDA Receptor Contributions to Visual Contrast Coding

Do Sensory Cortices Process More than One Sensory Modality during Perceptual Judgments?

Luis Lemus, Adrián Hernández, Rogelio Luna, Antonio Zainos, Ranulfo Romo. Recent studies have reported that sensory cortices process more than one sensory modality, challenging the long-lasting concept that they process only one. However, both the id… . . . → Read More: Do Sensory Cortices Process More than One Sensory Modality during Perceptual Judgments?

Oscillations and Filtering Networks Support Flexible Routing of Information

Thomas Akam, Dimitri M. Kullmann. The mammalian brain exhibits profuse interregional connectivity. How information flow is rapidly and flexibly switched among connected areas remains poorly understood. Task-dependent changes in th…. . . . → Read More: Oscillations and Filtering Networks Support Flexible Routing of Information

Basal GABA Regulates GABABR Conformation and Release Probability at Single Hippocampal Synapses

Tal Laviv, Inbal Riven, Iftach Dolev, Irena Vertkin, Bartosz Balana, Paul A. Slesinger, Inna Slutsky. Presynaptic GABAB receptor (GABABR) heterodimers are composed of GB1a/GB2 subunits and critically influence synaptic and cognitive functions.

Going Tubular in the Rostral Migratory Stream: Neurons Remodel Astrocyte Tubes to Promote Directional Migration in the Adult Brain

Tae-Yeon Eom, Jingjun Li, E.S. Anton. Newly generated neuroblasts from the subventricular zone of the adult brain migrate as neuronal chains within a network of astroglial tubes in the rostral migratory stream. This highly directed, r…. . . . → Read More: Going Tubular in the Rostral Migratory Stream: Neurons Remodel Astrocyte Tubes to Promote Directional Migration in the Adult Brain

The Multisensory Nature of Unisensory Cortices: A Puzzle Continued

Christoph Kayser. Multisensory integration is central to perception, and recent work drafts it as a distributed process involving many and even primary sensory cortices. Studies in behaving animals performing a mul…. . . . → Read More: The Multisensory Nature of Unisensory Cortices: A Puzzle Continued

Pausing to Regroup: Thalamic Gating of Cortico-Basal Ganglia Networks

Catherine A. Thorn, Ann M. Graybiel. How the cholinergic and dopaminergic systems of the striatum interact and how these interface with the massive neocortical input to the striatum are classic questions of cardinal interest to neuro…. . . . → Read More: Pausing to Regroup: Thalamic Gating of Cortico-Basal Ganglia Networks
