The world through a rat's whiskers - Rat Behavior
WEBLearn how rats use their whiskers to explore the world, how whiskers grow and change, and how they are processed in the brain. Find out about whisker mutations, whisker loss, and whisker plasticity.
The Euler spiral of rat whiskers | Science Advances - AAAS
WEBJan 15, 2020 · We show that the variety of whiskers on a rat’s cheek, each of which has different lengths and shapes, can be described by a simple mathematical equation such that each whisker is represented as an interval on the Euler spiral.
The secret to a rat’s sense of touch? It’s all in how the whiskers …
WEBApr 1, 2021 · Learn how rats use their whiskers to explore their environment and communicate with their brains. Scientists develop a mechanical model of whisker/follicle interactions to understand the...
Whisker-Mediated Touch System in Rodents: From Neuron to …
WEBAug 21, 2019 · Rat vibrissae, or whiskers, form a grid-wise layout on either side of the snout. The main distinction of the vibrissae from ordinary hairs is their large follicles which contain dense nerve terminals and sensory receptors.
What can whiskers tell us about mammalian evolution, …
WEBMay 25, 2021 · In rats, whisker movements start with small, unilateral retraction movements in the first postnatal week (Grant et al. 2012a). These can occur when the rats are sleeping, as small, asynchronous whisker twitches (Tiriac et al. 2012).
First 3D simulation of rat’s complete whisker system acts as a …
WEBJul 14, 2021 · Northwestern University engineers have developed the first full, three-dimensional (3D), dynamic simulation of a rat’s complete whisker system, offering rare, realistic insight into how rats obtain tactile information.
Sensorimotor processing in the rodent barrel cortex
WEBJul 31, 2019 · Whisker sensation is an active process, in which mice and rats scan their environment by moving their whiskers back and forth at high frequency (~10 Hz) when aroused or curious.
'Where' and 'what' in the whisker sensorimotor system
WEBSep 1, 2008 · Rats and mice generate their sense of touch through active movement of their whiskers. From signals that originate in sensory receptors at the base of the whisker, the brain builds up...
The Rat's Euler Whiskers - TheScienceBreaker
WEBJul 13, 2020 · Rats have notably long whiskers. We wondered how one can best describe the shape of those whiskers. Our extensive analysis of 523 whiskers led us to conclude that all the whiskers on a rat's cheek can be well approximated by segments of a Euler Spiral.
How Rats Feel: A Whisker's Tale - NPR
WEBApr 8, 2011 · Rats don't have sharp vision, so they rely on whiskers to help them navigate. Reporting in PLoS Computational Biology, engineer Mitra Hartmann, of Northwestern University, and colleagues...
