Target‐specific control of piriform cortical output via distinct inhibitory circuits

Autor: Cora Sau Wan Lai, Huanhuan Li, Anni Guo, Hehai Jiang, Arthur Chiu, Chunyue Geoffrey Lau

Publikováno v: The FASEB Journal. 35

Information represented by principal neurons in anterior piriform cortex (APC) is regulated by local, recurrent excitation and inhibition, but the circuit mechanisms remain elusive. Two types of layer 2 (L2) principal neurons, semilunar (SL), and sup

Networks in the spinal cord, which are responsible for the generation of rhythmic movements, commonly known as central pattern generators (CPGs), have remained elusive for decades. Although it is well-known that many spinal neurons are rhythmically a

Optical manipulations reveal strong reciprocal inhibition but limited recurrent excitation within olfactory bulb glomeruli

Autor: Nathan E. Schoppa, Joseph D. Zak

The local circuitry within olfactory bulb glomeruli filters, transforms, and facilitates information transfer from olfactory sensory neurons to bulb output neurons. Two key elements of this circuit are glutamatergic tufted cells (TCs) and GABAergic p

Correction for Jensen et al., Multiple cannabinoid signaling cascades powerfully suppress recurrent excitation in the hippocampus

Autor: Kaoutsar Nasrallah, Pablo E. Castillo, Coralie Berthoux, Kyle R. Jensen

Publikováno v: Proc Natl Acad Sci U S A

Recurrent excitatory neural networks are unstable. In the hippocampus, excitatory mossy cells (MCs) receive strong excitatory inputs from dentate granule cells (GCs) and project back onto the proximal dendrites of GCs. By targeting the ipsi- and cont

A Disinhibitory Circuit for Contextual Modulation in Primary Visual Cortex

Autor: Kenneth D. Miller, Andreas J Keller, Massimo Scanziani, Mario Dipoppa, Matthew S. Caudill, Morgane M. Roth, Alessandro Ingrosso

Publikováno v: Neuron

Context guides perception by influencing stimulus saliency. Accordingly, in visual cortex, responses to a stimulus are modulated by context, the visual scene surrounding the stimulus. Responses are suppressed when stimulus and surround are similar bu

A speed-accurate self-sustaining head direction cell path integration model without recurrent excitation

Autor: Daniel Walters, Simon M. Stringer, Page Hji.

Publikováno v: Network: Computation in Neural Systems. 29:37-69

The head direction (HD) system signals HD in an allocentric frame of reference. The system is able to update firing based on internally derived information about self-motion, a process known as path integration. Of particular interest is how path int

Sub-populations of Spinal V3 Interneurons Form Focal Modules of Layered Pre-motor Microcircuits

Autor: Jeremy W, Chopek, Filipe, Nascimento, Marco, Beato, Robert M, Brownstone, Ying, Zhang

Cell Reports

Summary Layering of neural circuits facilitates the separation of neurons with high spatial sensitivity from those that play integrative temporal roles. Although anatomical layers are readily identifiable in the brain, layering is not structurally ob
