Degeneracy in hippocampal physiology and plasticity

RK Rathour, R Narayanan - Hippocampus, 2019 - Wiley Online Library
Degeneracy, defined as the ability of structurally disparate elements to perform analogous
function, has largely been assessed from the perspective of maintaining robustness of …

Active dendrites: colorful wings of the mysterious butterflies

D Johnston, R Narayanan - Trends in neurosciences, 2008 - cell.com
Santiago Ramón y Cajal had referred to neurons as the ‘mysterious butterflies of the soul.'
Wings of these butterflies – their dendrites – were traditionally considered as passive …

Homeostasis of functional maps in active dendrites emerges in the absence of individual channelostasis

RK Rathour, R Narayanan - Proceedings of the National …, 2014 - National Acad Sciences
The maintenance of ion channel homeostasis, or channelostasis, is a complex puzzle in
neurons with extensive dendritic arborization, encompassing a combinatorial diversity of …

Inactivating ion channels augment robustness of subthreshold intrinsic response dynamics to parametric variability in hippocampal model neurons

RK Rathour, R Narayanan - The Journal of physiology, 2012 - Wiley Online Library
Key points • Voltage‐gated ion channels (VGICs) play a critical role in determining how neurons
respond to oscillatory inputs at various frequencies. How do inactivating VGICs regulate …

Analogous synaptic plasticity profiles emerge from disparate channel combinations

A Anirudhan, R Narayanan - Journal of Neuroscience, 2015 - Soc Neuroscience
An open question within the Bienenstock-Cooper-Munro theory for synaptic modification
concerns the specific mechanism that is responsible for regulating the sliding modification …

[HTML][HTML] A calcium-dependent plasticity rule for HCN channels maintains activity homeostasis and stable synaptic learning

S Honnuraiah, R Narayanan - PloS one, 2013 - journals.plos.org
Theoretical and computational frameworks for synaptic plasticity and learning have a long
and cherished history, with few parallels within the well-established literature for plasticity of …

Catalytic enantioselective 1, 3-dipolar cycloadditions of azomethine ylides for biology-oriented synthesis

R Narayan, M Potowski, ZJ Jia… - Accounts of Chemical …, 2014 - ACS Publications
Conspectus Cycloaddition reactions are among the most powerful methods for the
synthesis of complex compounds. In particular, the development and application of the 1,3-dipolar …

[PDF][PDF] Long-term potentiation in rat hippocampal neurons is accompanied by spatially widespread changes in intrinsic oscillatory dynamics and excitability

R Narayanan, D Johnston - Neuron, 2007 - cell.com
Oscillations in neural activity are a prominent feature of many brain states. Individual
hippocampal neurons exhibit intrinsic membrane potential oscillations and intrinsic resonance in …

The h channel mediates location dependence and plasticity of intrinsic phase response in rat hippocampal neurons

R Narayanan, D Johnston - Journal of Neuroscience, 2008 - Soc Neuroscience
The presence of phenomenological inductances in neuronal membrane has been known
for more than one-half a century. Despite this, the dramatic contributions of such inductive …

[PDF][PDF] Calcium store depletion induces persistent perisomatic increases in the functional density of h channels in hippocampal pyramidal neurons

R Narayanan, KJ Dougherty, D Johnston - Neuron, 2010 - cell.com
The regulation of intracellular calcium by the endoplasmic reticulum (ER) plays a critical role
in neuronal function. While the consequences associated with depleting calcium from the …
