Gastrin-releasing peptide (GRP) signalling regulates vasoactive-intestinal peptide (VIP)-expressing cortical cells in a disinhibitory microcircuit that modulates a cortex-dependent behaviour.
In a mouse model of mesial temporal lobe epilepsy, reactive hippocampal glia were reprogrammed into functional GABAergic interneurons that integrated into local circuits and reduced seizure incidence.
Targeting two neuronal populations simultaneously with brief bursts of deep brain stimulation (DBS) induces longer-lasting beneficial effects on motor function than conventional DBS in dopamine-depleted mice.
Synaptic dysfunction is a key feature of Alzheimer disease. In this Review, Padmanabhan, Kneynsberg and Götz examine insights provided by super-resolution microscopy into synaptic architecture and organization in Alzheimer disease, focusing on amyloid-β and tau, thought to be two key players in the pathophysiology of the disease.
Hands enable us to interact with objects in precise and versatile ways. In this Review, Sobinov and Bensmaia discuss aspects of mundane and expert manual behaviours, the anatomical complexity of the human hand and neural mechanisms that underlie manual dexterity.
The encoding of itch by peripheral and central neural circuits is a topic of long-standing interest in the somatosensory field. Here, Zhou-Feng Chen outlines a model for itch coding that emphasizes the role of neuropeptides in conveying itch information from the periphery to the spinal cord.
