Vertebrate versus invertebrate neural circuits [PDF]

open access: yesCurrent Biology, 2013
SummaryThe recent Cell Symposium ‘Genes, Circuits and Behavior’ brought together researchers working on neural circuits in vertebrate and invertebrate species. In the interest of fostering communication across the ‘backbone-divide’, we asked a number of neuroscientists from both camps for their views on the extent to which insights obtained from ...

Context-dependent serotonin signaling links dietary quality to foraging decisions

open access: yesNature Communications
Animals sense their metabolic needs to guide adaptive behaviors partly through serotonin, a neurotransmitter associated with feeding in many species.

Resolving the prevalence of somatic transposition in Drosophila

open access: yeseLife, 2017
Somatic transposition in mammals and insects could increase cellular diversity and neural mobilization has been implicated in age-dependent decline.

Convergent direct and indirect cortical streams shape avoidance decisions in mice via the midline thalamus

open access: yesNature Communications
Current concepts of corticothalamic organization in the mammalian brain are mainly based on sensory systems, with less focus on circuits for higher-order cognitive functions.

Sensory neurons couple arousal and foraging decisions in Caenorhabditis elegans

open access: yeseLife, 2023
Foraging animals optimize feeding decisions by adjusting both common and rare behavioral patterns. Here, we characterize the relationship between an animal’s arousal state and a rare decision to leave a patch of bacterial food.

A geographically distributed bio-hybrid neural network with memristive plasticity [PDF]

open access: yes, 2017
Throughout evolution the brain has mastered the art of processing real-world inputs through networks of interlinked spiking neurons. Synapses have emerged as key elements that, owing to their plasticity, are merging neuron-to-neuron signalling with ...

TrakEM2 Software for Neural Circuit Reconstruction

open access: yesPLoS ONE, 2012
A key challenge in neuroscience is the expeditious reconstruction of neuronal circuits. For model systems such as Drosophila and C. elegans, the limiting step is no longer the acquisition of imagery but the extraction of the circuit from images. For this purpose, we designed a software application, TrakEM2, that addresses the systematic reconstruction ...

Stable chaos in fluctuation driven neural circuits

open access: yes, 2014
We study the dynamical stability of pulse coupled networks of leaky integrate-and-fire neurons against infinitesimal and finite perturbations. In particular, we compare current versus fluctuations driven networks, the former (latter) is realized by ...

Hippocampal synchrony dynamically gates cortical connectivity across brain states

open access: yesScientific Reports
Memory consolidation is thought to rely on hippocampo-cortical dialogue orchestrated by three cardinal sleep oscillations: cortical slow oscillations, thalamic spindles, and hippocampal sharp-wave ripples.
