Mixed Multi-Level Visual, Reward, and Motor Signals in Dorsomedial Frontal Cortex Area F7 during Active Naturalistic Video Exploration

Posted by klaurent Rockefeller

Kavli Affiliate: Winrich Freiwald | Authors: Farid Aboharb, Stephen Serene, Julia Sliwa and Winrich A Freiwald | Summary: In the primate brain the frontal lobes support complex functions, including social cognition. Understanding the functional organization of these regions requires an approach for rich functional characterization. Here we used a novel paradigm, the visual exploration of […]

Ventral CA1 Population Codes for Anxiety

Posted by klaurent Columbia

Kavli Affiliate: Stefano Fusi | Authors: Sean Chih-Hsiung Lim, Stefano Fusi and Rene Hen | Summary: The ventral hippocampus is a critical node in the distributed brain network that controls anxiety. Using miniature microscopy and calcium imaging, we recorded ventral CA1 (vCA1) neurons in freely moving mice as they explored variants of classic behavioral assays […]

Dysregulation of astrocyte-secreted pleiotrophin contributes to neuronal structural and functional phenotypes in Down Syndrome

Posted by klaurent UCSD / Salk

Kavli Affiliate: Nicola Allen | Authors: Ashley N Brandebura, Quinn N Asbell, Mariel Kristine B Micael and Nicola J Allen | Summary: Neuronal dendrite structure and synapse formation is tightly regulated during development to promote proper connectivity. Astrocyte-secreted proteins act as guidance and pro-synaptogenic factors, and astrocyte protein secretion is dysregulated in neurodevelopmental disorders with […]

Host–pathogen–vector continuum in a changing landscape: Drivers of Bartonella prevalence and evidence of historic spillover in a tropical multi–host community

Posted by klaurent UCSD / Salk

Kavli Affiliate: V. S. Ramachandran | Authors: B.R. Ansil, Ashwin Viswanathan, Vivek Ramachandran, H.M. Yeshwanth, Avirup Sanyal and Uma Ramakrishnan | Summary: Our understanding of pathogen spillover is largely based on viral systems associated with bats. Bacterial infections of zoonotic origin also pose a significant public health burden, many of which are associated with small […]

Perisaccadic and Attentional Remapping of Receptive Fields in Lateral Intraparietal Area and Frontal Eye Fields

Posted by klaurent Columbia

Kavli Affiliate: Michael Goldberg | Authors: Xiao Wang, Cong Zhang, Lin Yang, Min Jin, Michael E Goldberg, Mingsha Zhang and Ning Qian | Summary: The nature and function of perisaccadic receptive-field (RF) remapping have been controversial. We used a delayed saccade task to reduce previous confounds and examined the remapping time course in areas LIP […]
