Species-specific wiring for direction selectivity in the mammalian retina

H Ding, RG Smith, A Poleg-Polsky, JS Diamond… - Nature, 2016 - nature.com
Directionally tuned signalling in starburst amacrine cell (SAC) dendrites lies at the heart of
the circuit that detects the direction of moving stimuli in the mammalian retina. The relative …

Motor learning drives dynamic patterns of intermittent myelination on learning-activated axons

…, L Conant, AR Chavez, A Poleg-Polsky… - Nature …, 2022 - nature.com
Myelin plasticity occurs when newly formed and pre-existing oligodendrocytes remodel
existing patterns of myelination. Myelin remodeling occurs in response to changes in neuronal …

An augmented two-layer model captures nonlinear analog spatial integration effects in pyramidal neuron dendrites

MP Jadi, BF Behabadi, A Poleg-Polsky… - Proceedings of the …, 2014 - ieeexplore.ieee.org
In pursuit of the goal to understand and eventually reproduce the diverse functions of the
brain, a key challenge lies in reverse engineering the peculiar biology-based “technology” that …

[HTML][HTML] Classical center-surround receptive fields facilitate novel object detection in retinal bipolar cells

…, SA Budoff, MJ Grybko, JB Hunt, A Poleg-Polsky - Nature …, 2022 - nature.com
Antagonistic interactions between center and surround receptive field (RF) components lie
at the heart of the computations performed in the visual system. Circularly symmetric center-…

[PDF][PDF] Functional compartmentalization within starburst amacrine cell dendrites in the retina

A Poleg-Polsky, H Ding, JS Diamond - Cell reports, 2018 - cell.com
Dendrites in many neurons actively compute information. In retinal starburst amacrine cells,
transformations from synaptic input to output occur within individual dendrites and mediate …

Dynamic compartmental computations in tuft dendrites of layer 5 neurons during motor behavior

…, M Abboud, O Barak, Y Schiller, A Poleg-Polsky… - Science, 2022 - science.org
Tuft dendrites of layer 5 pyramidal neurons form specialized compartments important for motor
learning and performance, yet their computational capabilities remain unclear. Structural-…

[HTML][HTML] Imperfect space clamp permits electrotonic interactions between inhibitory and excitatory synaptic conductances, distorting voltage clamp recordings

A Poleg-Polsky, JS Diamond - PLoS One, 2011 - journals.plos.org
The voltage clamp technique is frequently used to examine the strength and composition of
synaptic input to neurons. Even accounting for imperfect voltage control of the entire cell …

NMDA spikes mediate amplification of inputs in the rat piriform cortex

A Kumar, O Schiff, E Barkai, BW Mel, A Poleg-Polsky… - Elife, 2018 - elifesciences.org
10.7554/eLife.38446.001 The piriform cortex (PCx) receives direct input from the olfactory
bulb (OB) and is the brain's main station for odor recognition and memory. The transformation …

Dendritic spikes expand the range of well tolerated population noise structures

A Poleg-Polsky - Journal of Neuroscience, 2019 - Soc Neuroscience
The brain operates surprisingly well despite the noisy nature of individual neurons. The
central mechanism for noise mitigation in the nervous system is thought to involve averaging …

Retinal circuitry balances contrast tuning of excitation and inhibition to enable reliable computation of direction selectivity

A Poleg-Polsky, JS Diamond - Journal of Neuroscience, 2016 - Soc Neuroscience
Feedforward (FF) inhibition is a common motif in many neural networks. Typically, excitatory
inputs drive both principal neurons and interneurons; the interneurons then inhibit the …
