A mechanism for inter-areal coherence through communication based on connectivity and oscillatory power

Schneider et al. establish a mechanism for inter-areal coherence between field potentials, where it is the result and not the cause of communication. Consequently, coherence depends in a lawful manner on connectivity and power and does not require spiking entrainment. This mechanism explains behavior- related changes in fronto-parietal and LGN-V1 coherence.

Sleep and sensorimotor integration during early vocal learning in a songbird

Behavioural studies widely implicate sleep in memory consolidation in the learning of a broad range of behaviours. During sleep, brain regions are reactivated, and specific patterns of neural activity are replayed consistent with patterns observed in previous waking behaviour. Birdsong learning is a paradigmatic model system for skill learning...

Brain rhythms define distinct interaction networks with differential dependence on anatomy

Cognitive functions are subserved by rhythmic neuronal synchronization across widely distributed brain areas. In 105 area pairs, we investigated functional connectivity (FC) through coherence, power correlation, and Granger causality (GC) in the theta, beta, high-beta, and gamma rhythms. Between rhythms, spatial FC patterns were largely independent. Thus, the rhythms defined distinct interaction networks. Importantly, networks of coherence and GC were not explained by the spatial distributions of the strengths of the rhythms. Those networks, particularly the GC networks, contained clear modules, with typically one dominant rhythm per module. ....

Population-specific neuromodulation prolongs therapeutic benefits of deep brain stimulation

By Teresa A. Spix et al.
Journal: Science

Symptoms of neurological diseases emerge through the dysfunction of neural circuits whose diffuse and intertwined architectures pose serious challenges for delivering therapies. Deep brain stimulation (DBS) improves Parkinson’s disease symptoms acutely but does not differentiate between neuronal circuits, and its effects decay rapidly if stimulation is discontinued. Recent findings suggest that optogenetic manipulation of distinct neuronal subpopulations in the external globus pallidus (GPe) provides long- lasting therapeutic effects in dopamine-depleted (DD) mice. We used synaptic differences to excite parvalbumin-expressing GPe neurons and inhibit lim-homeobox-6–expressing GPe neurons simultaneously using brief bursts of electrical stimulation...

The nematode C. elegans senses airborne sound

By Adam J. Iliff et al.
Journal: Neuron

Hearing is thought to exist only in vertebrates and some arthropods, but not other animal phyla. Here, Xu and colleagues report that the earless nematode C. elegans senses airborne sound and engages in phonotaxis. Thus, hearing might have evolved multiple times independently in the animal kingdom, suggesting convergent evolution.
