Connectivity, plasticity, and function of neuronal circuits in the zebrafish olfactory forebrain [PDF]

open access: yes, 2014
For most living animals such as worms, insects, fishes, rodents and humans, chemical cues from the environment (odorants) play critical roles in guiding behaviors important for survival, including preying, mating, breeding, and escaping.

SNAP-25 phosphorylation at Ser187 regulates synaptic facilitation and short-term plasticity in an age-dependent manner

open access: yesScientific Reports, 2017
Neurotransmitter release is mediated by the SNARE complex, but the role of its phosphorylation has scarcely been elucidated. Although PKC activators are known to facilitate synaptic transmission, there has been a heated debate on whether PKC mediates ...

Analyzing Developing Brain-On-Chip Cultures with the CALIMA Calcium Imaging Tool

open access: yesMicromachines, 2021
Brain-on-chip (BoC) models are tools for reproducing the native microenvironment of neurons, in order to study the (patho)physiology and drug-response of the brain.

A kinematic model of stick‐insect walking

open access: yesPhysiological Reports, 2019
Animal, and insect walking (locomotion) in particular, have attracted much attention from scientists over many years up to now. The investigations included behavioral, electrophysiological experiments, as well as modeling studies.

Neuronal avalanches differ from wakefulness to deep sleep - evidence from intracranial depth recordings in humans [PDF]

open access: yes, 2013
Neuronal activity differs between wakefulness and sleep states. In contrast, an attractor state, called self-organized critical (SOC), was proposed to govern brain dynamics because it allows for optimal information coding.

Multimodal Modeling of Neural Network Activity: Computing LFP, ECoG, EEG, and MEG Signals With LFPy 2.0

open access: yesFrontiers in Neuroinformatics, 2018
Recordings of extracellular electrical, and later also magnetic, brain signals have been the dominant technique for measuring brain activity for decades.

A small world of neuronal synchrony [PDF]

open access: yes, 2008
A small-world network has been suggested to be an efficient solution for achieving both modular and global processing-a property highly desirable for brain computations.

Unique Features of Network Bursts Emerge From the Complex Interplay of Excitatory and Inhibitory Receptors in Rat Neocortical Networks

open access: yesFrontiers in Cellular Neuroscience, 2019
Spontaneous network activity plays a fundamental role in the formation of functional networks during early development. The landmark of this activity is the recurrent emergence of intensive time-limited network bursts (NBs) rapidly spreading across the ...
