Associate Latent Encodings in Learning from Demonstrations

We contribute a learning from demonstration approach for robots to acquire skills from multi-modal high-dimensional data. Both latent representations and associations of different modalities are proposed to be jointly learned through an adapted variational ...

Parallel pathways from whisker and visual sensory cortices to distinct frontal regions of mouse neocortex

Carl Petersen, Varun Sreenivasan, Céline Matéo, Alexandros Kyriakatos

The spatial organization of mouse frontal cortex is poorly understood. Here, we used voltage-sensitive dye to image electrical activity in the dorsal cortex of awake head-restrained mice. Whisker-deflection evoked the earliest sensory response in a localiz ...

Perceptual learning is specific beyond vision and decision making

Michael Herzog, Aline Françoise Cretenoud, Lukasz Grzeczkowski, Fred Mast

Perceptual learning is usually assumed to occur within sensory areas or when sensory evidence is mapped onto decisions. Subsequent procedural and motor processes, involved in most perceptual learning experiments, are thought to play no role in the learning ...

Entrainment of Voluntary Movement to Undetected Auditory Regularities

Olaf Blanke, Leila Cammoun, Nathan Quentin Faivre, Aaron Schurger

In physics “entrainment” refers to the synchronization of two coupled oscillators with similar fundamental frequencies. In behavioral science, entrainment refers to the tendency of humans to synchronize their movements with rhythmic stimuli. Here, we asked ...

Exploring the role of white matter connectivity in cortex maturation

Alessandra Griffa, Patric Hagmann, Petra Susan Hüppi

The maturation of the cortical gray matter (GM) and white matter (WM) are described as sequential processes following multiple, but distinct rules. However, neither the mechanisms driving brain maturation processes, nor the relationship between GM and WM m ...

Brain-controlled neuroprosthetic interventions to restore locomotion after contusion spinal cord injury in the rat

Marco Bonizzato

Spinal cord injury (SCI), second only to stroke, is the leading cause of paralysis. Therapies based on electrical stimulation of the spinal cord and other locomotor areas of the Nervous System improve motor control in people with neurotrauma. Neuromodulati ...

Preferential Enhancement of Sensory and Motor Axon Regeneration by Combining Extracellular Matrix Components with Neurotrophic Factors

Silvestro Micera, Daniel Santos

After peripheral nerve injury, motor and sensory axons are able to regenerate but inaccuracy of target reinnervation leads to poor functional recovery. Extracellular matrix (ECM) components and neurotrophic factors (NTFs) exert their effect on different ne ...

Synaptic patterning and the timescales of cortical dynamics

Alexander Kevin Seeholzer

Neocortical circuits, as large heterogeneous recurrent networks, can potentially operate and process signals at multiple timescales, but appear to be differentially tuned to operate within certain temporal receptive windows. The modular and hierarchical or ...

The gram-negative sensing receptor PGRP-LC contributes to grooming induction in Drosophila

Bruno Lemaitre

Behavioral resistance protects insects from microbial infection. However, signals inducing insect hygiene behavior are still relatively unexplored. Our previous study demonstrated that olfactory signals from microbes enhance insect hygiene behavior, and gu ...

Multi-modality Sensory Feedback: a pilot study

Huaiqi Huang

The aim of this study is to test the hypotheses that a multi-modality sensory feedback device, incorporating mechanotactile and vibrotactile feedback can increase the subjects’ performance in localization and intensity discrimination.To the best of our kno ...
