Pyramidal neurons switch from integrators in vitro to resonators under in vivo-like conditions
During wakefulness, pyramidal neurons in the intact brain are bombarded by synaptic input
that causes tonic depolarization, increased membrane conductance (ie, shunting), and noisy …

Nonlinear interaction between shunting and adaptation controls a switch between integration and coincidence detection in pyramidal neurons
The membrane conductance of a pyramidal neuron in vivo is substantially increased by
background synaptic input. Increased membrane conductance, or shunting, does not simply …

[PDF][PDF] Absence of paresthesia during high-rate spinal cord stimulation reveals importance of synchrony for sensations evoked by electrical stimulation
Electrically activating mechanoreceptive afferents inhibits pain. However, paresthesia
evoked by spinal cord stimulation (SCS) at 40–60 Hz becomes uncomfortable at high pulse …

[PDF][PDF] Impact of neuronal properties on network coding: roles of spike initiation dynamics and robust synchrony transfer
Neural networks are more than the sum of their parts, but the properties of those parts are
nonetheless important. For instance, neuronal properties affect the degree to which neurons …

ClC-2 channels regulate neuronal excitability, not intracellular chloride levels
S Ratté, SA Prescott - Journal of Neuroscience, 2011 - Soc Neuroscience
Synaptic inhibition by GABA A receptors requires a transmembrane chloride gradient.
Hyperpolarization or shunting results from outward current produced by chloride flowing down this …

Single neuron firing properties impact correlation-based population coding
Correlated spiking has been widely observed, but its impact on neural coding remains
controversial. Correlation arising from comodulation of rates across neurons has been shown to …

Criticality and degeneracy in injury-induced changes in primary afferent excitability and the implications for neuropathic pain
S Ratté, Y Zhu, KY Lee, SA Prescott - Elife, 2014 - elifesciences.org
10.7554/eLife.02370.001 Neuropathic pain remains notoriously difficult to treat despite
numerous drug targets. Here, we offer a novel explanation for this intractability. Computer …

Differentially synchronized spiking enables multiplexed neural coding
M Lankarany, D Al-Basha, S Ratté… - Proceedings of the …, 2019 - National Acad Sciences
Multiplexing refers to the simultaneous encoding of two or more signals. Neurons have been
shown to multiplex, but different stimuli require different multiplexing strategies. Whereas …

Pain processing by spinal microcircuits: afferent combinatorics
SA Prescott, S Ratté - Current opinion in neurobiology, 2012 - Elsevier
Pain, itch, heat, cold, and touch represent different percepts arising from somatosensory input.
How stimuli give rise to these percepts has been debated for over a century. Recent work …
