Anatomical and functional characterization of neocortical circuits involved in transforming whisker sensory processing into goal-directed licking

The choice of an action upon perception of an external stimulus, arriving at a sensory organ of an animal, depends on previous experiences and outcomes throughout its life. In the rodent brain, the underlying mechanisms involved in simple sensorimotor tran ...

An Algorithm for Odor Source Localization based on Source Term Estimation

Alcherio Martinoli, Ali Marjovi, Faezeh Rahbar

Finding sources of airborne chemicals with mobile sensing systems finds applications across the security, safety, domestic, medical, and environmental domains. In this paper, we present an algorithm based on source term estimation for odor source localizat ...

Exploring the use of native spider silk as an optical fibre for chemical sensing

Luc Thévenaz, Kenny Hey Tow, Isabelle Dicaire, Desmond Chow Ming Chia

A spider uses up to seven different types of silk, all having specific functions, as building material, weapon and sensory organ to detect the presence of preys on its web. Recently, scientists have put under the limelight the extraordinary properties of t ...

Input-dependent regulation of excitability controls dendritic maturation in somatosensory thalamocortical neurons

Johannes Gräff, Jose Vicente Sanchez Mut

Input from the sensory organs is required to pattern neurons into topographical maps during development. Dendritic complexity critically determines this patterning process; yet, how signals from the periphery act to control dendritic maturation is unclear. ...

From spider webs to a fibre-optic chemical sensor

Luc Thévenaz, Kenny Hey Tow, Isabelle Dicaire, Desmond Chow Ming Chia

From the spider’s perspective, silk is not only a building material but also a safety net, a weapon and a sensory organ to detect the presence of prey on its web. For scientists, dragline silk - directly extracted from spiders - is a tough, biodegradable a ...

Weaving our way towards a new generation of ﬁbre-optic chemical sensors based on spider silk

Luc Thévenaz, Kenny Hey Tow, Isabelle Dicaire, Desmond Chow Ming Chia

From the spider’s perspective, silk is not only a building material but also a safety net, a weapon and a sensory organ to detect the presence of preys on its web. Indeed, this primeval material has been shaped over hundreds of millions of years by spiders ...

From the early steps of whisker formation to its evolutionary disappearance: the (curious) case of Prdm1 and its regulation

Pierluigi Giuseppe Manti

Whiskers (also known as vibrissae) are sensory organs that are thought to have first appeared in Therapsida, a group of synapsids that includes mammals and evolutionary ancestors like the Thrinaxodon(1). They are highly conserved among mammals to the notab ...

Elucidating the role of Hmx1 during mouse development

Linda Bapst

This thesis focuses on the study of H6 homeobox 1 (HMX1) gene, a homeobox-containing transcription factor involved in sensory organ and eye development and responsible for the oculo-auricular syndrome of Schorderet-Munier-Franceschetti. The purpose of my s ...

Behaviour-dependent recruitment of long-range projection neurons in somatosensory cortex

Bernard Schneider, Stefano Carta

In the mammalian neocortex, segregated processing streams are thought to be important for forming sensory representations of the environment(1,2), but how local information in primary sensory cortex is transmitted to other distant cortical areas during beh ...

Bio-inspired and probabilistic algorithms for distributed odor source localization using mobile robots

Thomas Lochmatter

We compare six different algorithms for localizing odor sources with mobile robots. Three algorithms are bio-inspired and mimic the behavior of insects when exposed to airborne pheromones. Two algorithms are based on probability and information theory, and ...
