Cortical synapses of the world's smallest mammal: An FIB/SEM study in the Etruscan shrew
Journal of Comparative Neurology, Volume 531, Issue 3, Page 390-414, February 2023., 2023 The present work provides a quantitative dataset of synapses from the Etruscan shrew (the smallest known terrestrial mammal). We have identified common and differing principles of synaptic organization compared to other mammalian species. Abstract The main aim of the present study was to determine if synapses from the exceptionally small brain of the ...

BCI learning induces core-periphery reorganization in M/EEG multiplex brain networks [PDF]
, 2020 Brain-computer interfaces (BCIs) constitute a promising tool for communication and control. However, mastering non-invasive closed-loop systems remains a learned skill that is difficult to develop for a non-negligible proportion of users. The involved learning process induces neural changes associated with a brain network reorganization that remains ...

Eph and ephrin signaling in the development of the central auditory system
Developmental Dynamics, Volume 252, Issue 1, Page 10-26, January 2023., 2023 Abstract Acoustic communication relies crucially on accurate interpretation of information about the intensity, frequency, timing, and location of diverse sound stimuli in the environment. To meet this demand, neurons along different levels of the auditory system form precisely organized neural circuits.

Wiring the senses: Factors that regulate peripheral axon pathfinding in sensory systems
Developmental Dynamics, Volume 252, Issue 1, Page 81-103, January 2023., 2023 Abstract Sensory neurons of the head are the ones that transmit the information about the external world to our brain for its processing. Axons from cranial sensory neurons sense different chemoattractant and chemorepulsive molecules during the journey and in the target tissue to establish the precise innervation with brain neurons and/or receptor ...

Pain‐autonomic measures reveal nociceptive sensitization in complex regional pain syndrome
European Journal of Pain, Volume 27, Issue 1, Page 72-85, January 2023., 2023 Abstract Background Allodynia and hyperalgesia are common signs in individuals with complex regional pain syndrome (CRPS), mainly attributed to sensitization of the nociceptive system. Appropriate diagnostic tools for the objective assessment of such hypersensitivities are still lacking, which are essential for the development of mechanism‐based ...

EcoMat, Volume 5, Issue 2, February 2023., 2023 In this paper, a self‐powered virtual olfactory generation system is fabricated based on an ultrafast voltage‐elevation triboelectric nanogenerator. This system has two operation chambers, where the electrospray devices are in the front chamber and the electrostatic‐field accelerated evaporation process is occurred in the back.

Sensorimotor incongruence and body perception: an experimental investigation
Frontiers in Human Neuroscience, 2013 Objectives: Several studies have shown that mirrored arm or leg movements are related to altered body sensations. This includes the alleviation of chronic pain using congruent mirror feedback and the induction of abnormal sensation in healthy ...

A 20-Channel Magnetoencephalography System Based on Optically Pumped Magnetometers [PDF]
, 2017 We describe a multichannel magnetoencephalography (MEG) system that uses optically pumped magnetometers (OPMs) to sense the magnetic fields of the human brain. The system consists of an array of 20 OPM channels conforming to the human subject's head, a person-sized magnetic shield containing the array and the human subject, a laser system to drive the ...
