Voltage fluctuations in neurons: signal or noise?

Y Yarom, J Hounsgaard - Physiological reviews, 2011 - journals.physiology.org
Noise and variability are fundamental companions to ion channels and synapses and thus
inescapable elements of brain function. The overriding unresolved issue is to what extent …

Synaptic input and temperature influence sensory coding in a mechanoreceptor

JS Scherer, K Sandbote, BL Schultze… - Frontiers in Cellular …, 2023 - frontiersin.org
Many neurons possess more than one spike initiation zone (SIZ), which adds to their

Computational model of touch sensory cells (T Cells) of the leech: role of the afterhyperpolarization (AHP) in activity-dependent conduction failure

E Cataldo, M Brunelli, JH Byrne, E Av-Ron… - Journal of computational …, 2005 - Springer
Bursts of spikes in T cells produce an AHP, which results from activation of a Na+/K+ pump
and a Ca 2+-dependent K+ current. Activity-dependent increases in the AHP are believed to …

Convergence of mechanosensory inputs onto neuromodulatory serotonergic neurons in the leech

N Velázquez‐Ulloa, SE Blackshaw… - Journal of …, 2003 - Wiley Online Library
By the frequency‐dependent release of serotonin, Retzius neurons in the leech modulate
diverse behavioral responses of the animal. However, little is known about how their firing …

The spontaneous electrical activity of neurons in leech ganglia

M Moshtagh‐Khorasani, EW Miller… - Physiological …, 2013 - Wiley Online Library
Using the newly developed voltage‐sensitive dye VF2. 1. Cl, we monitored simultaneously
the spontaneous electrical activity of~ 80 neurons in a leech ganglion, representing around …

Location and intensity discrimination in the leech local bend response quantified using optic flow and principal components analysis

SM Baca, EE Thomson… - Journal of …, 2005 - journals.physiology.org
In response to touches to their skin, medicinal leeches shorten their body on the side of the
touch. We elicited local bends by delivering precisely controlled pressure stimuli at different …

Initial variability and time-dependent changes of neuronal response features are cell-type-specific

JS Scherer, OE Riedesel, I Arkhypchuk… - Frontiers in Cellular …, 2022 - frontiersin.org
Different cell types are commonly defined by their distinct response features. But several
studies proved substantial variability between cells of the same type, suggesting rather the …

Highly variable spike trains underlie reproducible sensorimotor responses in the medicinal leech

D Zoccolan, G Pinato, V Torre - Journal of Neuroscience, 2002 - Soc Neuroscience
The nervous system of the leech is a particularly suitable model to investigate neural coding
of sensorimotor responses because it allows both observation of behavior and the …

Using optical flow to characterize sensory-motor interactions in a segment of the medicinal leech

D Zoccolan, V Torre - Journal of Neuroscience, 2002 - Soc Neuroscience
Activation of motoneurons innervating leech muscles causes the appearance of a two-
dimensional vector field of deformations on the skin surface that can be fully characterized …
