Neurexin drives C. elegans avoidance behavior independently of its post-synaptic binding partner Neuroligin

Posted by dbos UCSD / Salk

Kavli Affiliate: Sreekanth Chalasani | Authors: Caroline S Muirhead, Kirthi C Reddy, Sophia Guerra, Michael Rieger, Michael P Hart, Jagan Srinivasan and Sreekanth H Chalasani | Summary: Neurexins and their canonical binding partners, neuroligins, are localized to neuronal pre-, and post-synapses, respectively, but less is known about their role in driving behaviors. Here, we use […]

Astrocyte CCN1 stabilizes neural circuits in the adult brain

Posted by dbos UCSD / Salk

Kavli Affiliate: Nicola Allen | Authors: Laura Sancho, Matthew M Boisvert, Trinity Dawoodtabar, Jillybeth Burgado, Ellen Wang and Nicola J Allen | Summary: Neural circuits in many brain regions are refined by experience. Sensory circuits support higher plasticity at younger ages during critical periods – times of circuit refinement and maturation – and limit plasticity […]

Cervical collagen network porosity assessed by SHG endomicroscopy distinguishes preterm and normal pregnancy – a pilot study

Posted by dbos Hopkins

Kavli Affiliate: Xingde Li | Authors: Wenxuan Liang, Yuehan Liu, Honghua Guan, Vorada Sakulsaengprapha, Katherine Luby-Phelps, Mala Mahendroo and Xingde Li | Summary: Background Preterm birth (PTB) is a global public health issue affecting millions of newborns every year. Orchestrated remodeling of the cervix is essential for normal pregnancy and birth, while PTB is closely […]

An Amygdalar Oscillator Coordinates Cellular and Behavioral Rhythms

Posted by dbos Hopkins

Kavli Affiliate: Seth Blackshaw | Authors: Qiang Liu, Jiali Xiong, Dong Won Kim, Sang Soo Lee, Benjamin J. Bell, Chloe Alexandre, Seth Blackshaw, Alban Latremoliere and Mark N. Wu | Summary: Circadian rhythms are generated by the master pacemaker suprachiasmatic nucleus (SCN), in concert with local clocks throughout the body. While many brain regions exhibit […]

Modulation of GABAA receptor trafficking by WWC2 reveals class-specific mechanisms of synapse regulation by WWC family proteins

Posted by dbos Hopkins

Kavli Affiliate: Richard Huganir | Authors: Thomas L Dunham, Julia R Wilkerson, Richard C Johnson, Richard L. Huganir and Lenora J Volk | Summary: WWC2 (WW and C2 domain-containing protein) is implicated in several neurological disorders, however its function in the brain has yet to be determined. Here, we demonstrate that WWC2 interacts with inhibitory […]

Small molecule and cell contact-inducible systems for controlling expression and differentiation in stem cells

Posted by dbos UCSF

Kavli Affiliate: Hana El-Samad | Authors: Sarah S. Soliman, Devan H. Shah, Hana El-Samad and Zara Y. Weinberg | Summary: Synthetic developmental biology uses engineering approaches to understand multicellularity with goals ranging from recapitulating development to building synthetic organisms. Current approaches include engineering multicellular patterning, controlling differentiation, and implementing cooperative cellular behaviors in model systems. […]

Non-uniform contextual interactions in the visual cortex place fundamental limits on spatial vision

Posted by dbos Yale

Kavli Affiliate: Anirvan Nandy | Authors: Mitchell P Morton, Sachira Denagamage, Nyomi V Hudson and Anirvan S Nandy | Summary: A prevailing assumption in our understanding of how neurons in the primary visual cortex (V1) integrate contextual information is that such processes are spatially uniform. Conversely, perceptual phenomena such as visual crowding, the impaired ability […]

Cell type-specific dynamics of prefrontal gamma synchrony during flexible behavior

Posted by dbos UCSF

Kavli Affiliate: Vikaas Sohal | Authors: Aarron Justin Phensy, Lara Louise Hagopian and Vikaas Singh Sohal | Summary: The prefrontal cortex (PFC) is required for many cognitive processes that are disrupted in conditions such as schizophrenia. The PFC is composed of neuronal networks which are organized by both local microcircuitry and inter-regional projections, within which […]
