Remember this...


The failure of AD therapies in the clinic is driving the need to build strong preclinical data packages. Charles River offers comprehensive drug discovery services in patient derived cells and in vivo rodent and large animal models.

Our models are tested using a customizable multi-modal approach that includes imaging, cognitive testing, PK and neurochemical profiling.

Brief Communications

 

Excitatory connections between the prelimbic and infralimbic medial prefrontal cortex show a role for the prelimbic cortex in fear extinction    pp654 - 658
Roger Marek, Li Xu, Robert K. P. Sullivan & Pankaj Sah
doi:10.1038/s41593-018-0137-x

Prelimbic (PL) and infralimbic (IL) mPFC are thought to mediate fear expression and fear extinction, respectively. The authors show that PL projects to IL and innervates projections to amygdala and that this connection is engaged in fear extinction.

Articles

 

Tbr1 instructs laminar patterning of retinal ganglion cell dendrites    pp659 - 670
Jinyue Liu, Jasmine D. S. Reggiani, Mallory A. Laboulaye, Shristi Pandey, Bin Chen et al.
doi:10.1038/s41593-018-0127-z

Specific retinal connectivity depends on laminar restriction of neuronal processes. The authors show that a single transcription factor specifies a common laminar identity in dendrites of four retinal cell types, albeit via cell-type-specific means.

 

Synaptic nanomodules underlie the organization and plasticity of spine synapses    pp671 - 682

doi:10.1038/s41593-018-0138-9

Hruska et al. suggest an architectural basis for NMDAR-dependent spine plasticity mediated by addition of unitary pre- and postsynaptic nanomodules that function as building blocks of synaptic organization and enable structural plasticity.

 

Lifelong cortical myelin plasticity and age-related degeneration in the live mammalian brain    pp683 - 695
Robert A. Hill, Alice M. Li & Jaime Grutzendler
doi:10.1038/s41593-018-0120-6

It is unknown if myelination patterns are fixed in adults. Using label-free & fluorescence in vivo imaging, Hill et al show lifelong internode addition to partially myelinated axons, with age-related internode loss & debris accumulation in microglia.

 

Myelin remodeling through experience-dependent oligodendrogenesis in the adult somatosensory cortex    pp696 - 706
Ethan G. Hughes, Jennifer L. Orthmann-Murphy, Abraham J. Langseth & Dwight E. Bergles
doi:10.1038/s41593-018-0121-5

Oligodendrocytes are generated in adult somatosensory cortex, but few successfully integrate to form myelin. Sensory enrichment alters myelination patterns by enhancing oligodendrogenesis rather than altering the length of existing myelin sheaths.

 

Circuit dissection of the role of somatostatin in itch and pain    pp707 - 716
Jing Huang, Erika Polgár, Hans Jürgen Solinski, Santosh K. Mishra, Pang-Yen Tseng et al.
doi:10.1038/s41593-018-0119-z

Huang et al. demonstrate that somatostatin (Sst)-expressing primary afferents are pruriceptors. In spinal cord, they show that Sst potentiates itch by disinhibition involving dynorphin-expressing spinal neurons and that Sst also suppresses pain.

 

A hypothalamic circuit for the circadian control of aggression    pp717 - 724
William D. Todd, Henning Fenselau, Joshua L. Wang, Rong Zhang, Natalia L. Machado et al.
doi:10.1038/s41593-018-0126-0

Todd et al. show a daily rhythm in aggression propensity in male mice and reveal a novel polysynaptic circuit within the hypothalamus by which the central circadian clock (the suprachiasmatic nucleus) influences neurons that regulate attack behavior.

 

Locomotor activity modulates associative learning in mouse cerebellum    pp725 - 735
Catarina Albergaria, N. Tatiana Silva, Dominique L. Pritchett & Megan R. Carey
doi:10.1038/s41593-018-0129-x

Albergaria et al. demonstrate that ongoing locomotor activity modulates cerebellum-dependent associative learning. Optogenetic circuit dissection reveals a site of locomotor modulation within the mossy fiber pathway in the cerebellum.

 

Encoding of error and learning to correct that error by the Purkinje cells of the cerebellum    pp736 - 743
David J. Herzfeld, Yoshiko Kojima, Robijanto Soetedjo & Reza Shadmehr
doi:10.1038/s41593-018-0136-y

Herzfeld et al. examine how the cerebellum learns to correct movements. They find a timing code that links a Purkinje cell’s preference for error to its downstream projection on motor effectors that produce force to correct for that error.

 

Cortical drive and thalamic feed-forward inhibition control thalamic output synchrony during absence seizures    pp744 - 756
Cian McCafferty, François David, Marcello Venzi, Magor L. Lőrincz, Francis Delicata et al.
doi:10.1038/s41593-018-0130-4

The authors demonstrate that the thalamic output during absence seizures is controlled and synchronized by a combination of excitation from the cortex and fast feedforward inhibition from reticular thalamus, with little involvement of thalamocortical neuron intrinsic mechanisms.

 

The functional organization of cortical feedback inputs to primary visual cortex    pp757 - 764
Tiago Marques, Julia Nguyen, Gabriela Fioreze & Leopoldo Petreanu
doi:10.1038/s41593-018-0135-z

The authors measured the organization of cortical feedback inputs in mouse primary visual cortex. They found that the locations in visual cortex targeted by feedback axons relate to their tuning properties according to a simple geometrical rule.

 

Maternal IL-6 during pregnancy can be estimated from newborn brain connectivity and predicts future working memory in offspring    pp765 - 772
Marc D. Rudolph, Alice M. Graham, Eric Feczko, Oscar Miranda-Dominguez, Jerod M. Rasmussen et al.
doi:10.1038/s41593-018-0128-y

The authors show that maternal inflammation during pregnancy, indexed by IL-6, can be estimated from the newborn brain connectome and predicts future working memory performance in offspring at two years of age.
