Internal State Dependent Odor Processing and Perception—The Role of Neuromodulation in the Fly Olfactory System

open access: yesFrontiers in Cellular Neuroscience, 2018
Animals rely heavily on their sense of olfaction to perform various vital interactions with an ever-in-flux environment. The turbulent and combinatorial nature of air-borne odorant cues demands the employment of various coding strategies, which allow the

Exercise enhances motor skill learning by neurotransmitter switching in the adult midbrain

open access: yesNature Communications, 2020
Exercise promotes motor skill learning via unclear mechanisms. Here, the authors show that running wheel training results in neurotransmitter switching in caudal pedunculopontine nucleus neurons of mice.

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.

History-based action selection bias in posterior parietal cortex

open access: yesNature Communications, 2017
Past outcomes modulate activity in a diverse set of brain regions however their precise influence on decisions is not known. Here the authors show that posterior parietal cortex neurons encode history-related signals between trials and optogenetic ...

The application of neuMOS transistors to enhanced Built-in Self-Test (BIST) and product quality [PDF]

open access: yes, 1999
The neuMOS transistor is a comparatively new device developed in 1991 at Tohoku University, Japan, which is currently showing great promise in the direction of enhanced circuit functionality, particularly in Neural Network applications.

Novel competition test for food rewards reveals stable dominance status in adult male rats

open access: yesScientific Reports, 2021
Social hierarchy is a potent modulator of behavior, that is typically established through overt agonistic interactions between individuals in the group.

Strategies for recovering exact structure of neural circuits with broadly targeted fluorescent connectivity probes [PDF]

open access: yes, 2009
We present a framework for reconstructing structure of complete neural circuits in the brain using collections of independent measurements of connectivity performed with existing anatomical or functional fluorescent probes, and

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.

The neural circuits for arithmetic principles

open access: yesNeuroImage, 2017
Arithmetic principles are the regularities underlying arithmetic computation. Little is known about how the brain supports the processing of arithmetic principles. The current fMRI study examined neural activation and functional connectivity during the processing of verbalized arithmetic principles, as compared to numerical computation and general ...

Contextual behavior and neural circuits [PDF]

open access: yesFrontiers in Neural Circuits, 2013
Animals including humans engage in goal-directed behavior flexibly in response to items and their background, which is called contextual behavior in this review. Although the concept of context has long been studied, there are differences among researchers in defining and experimenting with the concept.
