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.

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.

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.

Selective dendritic localization of mRNA in Drosophila mushroom body output neurons

open access: yeseLife, 2021
Memory-relevant neuronal plasticity is believed to require local translation of new proteins at synapses. Understanding this process requires the visualization of the relevant mRNAs within these neuronal compartments.

A Pulse-Gated, Predictive Neural Circuit

open access: yes, 2016
Recent evidence suggests that neural information is encoded in packets and may be flexibly routed from region to region. We have hypothesized that neural circuits are split into sub-circuits where one sub-circuit controls information propagation via ...

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 ...

Models wagging the dog: are circuits constructed with disparate parameters? [PDF]

open access: yes, 2007
In a recent article, Prinz, Bucher, and Marder (2004) addressed the fundamental question of whether neural systems are built with a fixed blueprint of tightly controlled parameters or in a way in which properties can vary largely from one individual to ...

Stimulation of protein synthesis by optogenetic and chemical induction of excitatory synaptic plasticity in hippocampal somatostatin interneurons

open access: yesMolecular Brain, 2022
Somatostatin-expressing interneurons (SOM-INs) are a major subpopulation of GABAergic cells in CA1 hippocampus that receive excitation from pyramidal cells (PCs) and provide feedback control of synaptic inputs onto PC dendrites.

Metastability, Criticality and Phase Transitions in brain and its Models [PDF]

open access: yes, 2006
This essay extends the previously deposited paper "Oscillations, Metastability and Phase Transitions" to incorporate the theory of Self-organizing Criticality.

Complexity without chaos: Plasticity within random recurrent networks generates robust timing and motor control [PDF]

open access: yes, 2012
It is widely accepted that the complex dynamics characteristic of recurrent neural circuits contributes in a fundamental manner to brain function. Progress has been slow in understanding and exploiting the computational power of recurrent dynamics for ...
