High-performance probes for light and electron microscopy

S Viswanathan, ME Williams, EB Bloss, TJ Stasevich… - Nature …, 2015 - nature.com
We describe an engineered family of highly antigenic molecules based on GFP-like
fluorescent proteins. These molecules contain numerous copies of peptide epitopes and …

[HTML][HTML] Shared and distinct transcriptomic cell types across neocortical areas

…, J Goldy, E Garren, MN Economo, S Viswanathan… - Nature, 2018 - nature.com
The neocortex contains a multitude of cell types that are segregated into layers and functionally
distinct areas. To investigate the diversity of cell types across the mouse neocortex, here …

Subset of cortical layer 6b neurons selectively innervates higher order thalamic nuclei in mice

…, D Casas-Torremocha, E Grant, S Viswanathan… - Cerebral …, 2018 - academic.oup.com
The thalamus receives input from 3 distinct cortical layers, but input from only 2 of these has
been well characterized. We therefore investigated whether the third input, derived from …

Molecularly defined subplate neurons project both to thalamocortical recipient layers and thalamus

S Viswanathan, A Sheikh, LL Looger… - Cerebral cortex, 2017 - academic.oup.com
In mammals, subplate neurons (SPNs) are among the first generated cortical neurons. While
most SPNs exist only transiently during development, a number of SPNs persist among …

[PDF][PDF] A designer AAV variant permits efficient retrograde access to projection neurons

DGR Tervo, BY Hwang, S Viswanathan, T Gaj… - Neuron, 2016 - cell.com
Efficient retrograde access to projection neurons for the delivery of sensors and effectors
constitutes an important and enabling capability for neural circuit dissection. Such an approach …

Distinct descending motor cortex pathways and their roles in movement

MN Economo, S Viswanathan, B Tasic, E Bas… - Nature, 2018 - nature.com
Activity in the motor cortex predicts movements, seconds before they are initiated. This
preparatory activity has been observed across cortical layers, including in descending pyramidal …

Real-time quantification of single RNA translation dynamics in living cells

…, Z Zhang, LD Lavis, JB Grimm, S Viswanathan… - Science, 2016 - science.org
Although messenger RNA (mRNA) translation is a fundamental biological process, it has
never been imaged in real time in vivo with single-molecule precision. To achieve this, we …

Fixation-resistant photoactivatable fluorescent proteins for CLEM

…, MG Sun, G Shtengel, S Viswanathan… - Nature …, 2015 - nature.com
Fluorescent proteins facilitate a variety of imaging paradigms in live and fixed samples.
However, they lose their fluorescence after heavy fixation, hindering applications such as …

Changing microcircuits in the subplate of the developing cortex

S Viswanathan, S Bandyopadhyay… - Journal of …, 2012 - Soc Neuroscience
Subplate neurons (SPNs) are a population of neurons in the mammalian cerebral cortex that
exist predominantly in the prenatal and early postnatal period. Loss of SPNs prevents the …

[HTML][HTML] A single ClpS monomer is sufficient to direct the activity of the ClpA hexamer

GM De Donatis, SK Singh, S Viswanathan… - Journal of biological …, 2010 - ASBMB
ClpS is an adaptor protein that interacts with ClpA and promotes degradation of proteins
with N-end rule degradation motifs (N-degrons) by ClpAP while blocking degradation of …
