Upregulated extracellular matrix-related genes and impaired synaptic activity in dopaminergic and hippocampal neurons derived from Parkinson’s disease patients with PINK1 and PARK2 mutations

Posted by klaurent UCSD / Salk

Kavli Affiliate: Fred Gage | Authors: Utkarsh Tripathi, Idan Rosh, Ran Ben Ezer, Ritu Nayak, Ashwani Choudhary, Jose Djamus, Andreea Manole, Henry Houlden, Fred H. Gage and Shani Stern | Summary: Abstract Parkinson’s disease (PD) is the second most prevalent neurodegenerative disease. Primary symptoms of PD arise with the loss of dopaminergic (DA) neurons in […]

Two types of locus coeruleus norepinephrine neurons drive reinforcement learning

Posted by klaurent Hopkins

Kavli Affiliate: Jeremiah Cohen | Authors: Zhixiao Su and Jeremiah Y. Cohen | Summary: Abstract The cerebral cortex generates flexible behavior by learning. Reinforcement learning is thought to be driven by error signals in midbrain dopamine neurons. However, they project more densely to basal ganglia than cortex, leaving open the possibility of another source of […]

Visuomotor interactions in the mouse forebrain mediated by extrastriate cortico-cortical pathways

Posted by klaurent NTNU

Kavli Affiliate: Menno Witter, Jonathan Whitlock | Authors: Karoline Hovde, Ida V. Rautio, Andrea Marie Hegstad, Menno P. Witter and Jonathan R. Whitlock | Summary: Abstract The mammalian visual system can be broadly divided into two functional processing pathways: a dorsal stream supporting visually and spatially guided actions, and a ventral stream enabling object recognition. […]

Adult born hippocampal granule cells promote pattern separation by bidirectionally modulating the remapping of place and cue cells

Posted by klaurent Columbia

Kavli Affiliate: Rene Hen | Authors: Sebnem N. Tuncdemir, Andres D. Grosmark, Hannah Chung, Victor M. Luna, Clay O. Lacefield, Attila Losonczy and Rene Hen | Summary: Abstract The hippocampal dentate gyrus (DG) exhibits a unique form of neural plasticity that results from continuous integration of adult born neurons, referred to as ‘adult neurogenesis’. Recent […]

The alarm pheromone and alarm response of the clonal raider ant

Posted by klaurent Rockefeller

Kavli Affiliate: Daniel Kronauer | Authors: Lindsey E. Lopes, Erik T. Frank, Zsolt Kárpáti, Thomas Schmitt and Daniel J.C. Kronauer | Summary: Abstract Ants communicate via an arsenal of different pheromones produced in a variety of exocrine glands. For example, ants release alarm pheromones in response to danger to alert their nestmates and to trigger […]

Microdissection and culturing of adult lateral entorhinal cortex layer II neurons from APP/PS1 Alzheimer model mice

Posted by klaurent NTNU

Kavli Affiliate: Menno Witter, Asgeir Kobro-Flatmoen | Authors: Katrine Sjaastad Hanssen, Menno P. Witter, Axel Sandvig, Ioanna Sandvig and Asgeir Kobro-Flatmoen | Summary: Abstract Background Primary neuronal cultures enable cell-biological studies of Alzheimer’s disease (AD), albeit typically non-neuron-specific. The first cortical neurons affected in AD reside in layer II of the lateralmost part of the […]

Structural basis for CaVα2δ:gabapentin binding

Posted by klaurent UCSF

Kavli Affiliate: Daniel Minor | Authors: Daniel L Minor, Jr., Zhou Chen and Abhisek Mondal | Summary: Abstract Gabapentinoid drugs for pain and anxiety act on the CaVα2δ-1 and CaVα2δ-2 subunits of high-voltage activated calcium channels (CaV1s and CaV2s). Here, we present the cryo-EM structure of the gabapentin-bound brain and cardiac CaV1.2/CaVβ3/CaVα2δ-1 channel. The data […]
