A Unified Gas–Liquid Carbonation Platform for Habit-Controlled Calcite Nanostructures [PDF]

open access: yesNanomaterials
Calcite habit engineering offers a route to transform CO2 mineralization from bulk sequestration into value-added nanomaterial production. Here, we demonstrate that additive chemistry and seeding strategy can serve as separable, recipe-level levers for ...

Local inhibitory dynamics underpin temporal integration and functional segregation between barrels and septa in the mouse barrel cortex [PDF]

open access: yeseLife
Mice, like humans, enhance tactile perception through repeated sampling of spatially segregated sensory inputs. In the whisker system, individual whisker identity is preserved along the whisker-brainstem-thalamus-cortex pathway, culminating in distinct ...

Purkinje Cell Activity Resonation Generates Rhythmic Behaviors at the Preferred Frequency of 8 Hz

open access: yesBiomedicines, 2022
Neural activity exhibits oscillations, bursts, and resonance, enhancing responsiveness at preferential frequencies. For example, theta-frequency bursting and resonance in granule cells facilitate synaptic transmission and plasticity mechanisms at the ...

Demonstration of three-dimensional contact point determination and contour reconstruction during active whisking behavior of an awake rat.

open access: yesPLoS Computational Biology, 2022
The rodent vibrissal (whisker) system has been studied for decades as a model of active touch sensing. There are no sensors along the length of a whisker; all sensing occurs at the whisker base.

Voltage-Sensitive Dye versus Intrinsic Signal Optical Imaging: Comparison of Tactile Responses in Primary and Secondary Somatosensory Cortices of Rats

open access: yesBrain Sciences, 2021
Studies using functional magnetic resonance imaging assume that hemodynamic responses have roughly linear relationships with underlying neural activity.

Supra-orbital whiskers act as wind-sensing antennae in rats.

open access: yesPLoS Biology, 2023
We know little about mammalian anemotaxis or wind sensing. Recently, however, Hartmann and colleagues showed whisker-based anemotaxis in rats. To investigate how whiskers sense airflow, we first tracked whisker tips in anesthetized rats under low (0.5 m ...

Review: Adele E. Clarke, Carrie Friese & Rachel S. Washburn (2018). Situational Analysis: Grounded Theory After the Interpretive Turn

open access: yesForum: Qualitative Social Research, 2018
"Situational Analysis: Grounded Theory After the Interpretive Turn" is the second edition [2E] of Adele CLARKE's inspirational 2005 book [1E], where this new approach to qualitative research first appeared in the tradition of grounded theory methodology [

Growth behavior of tin whisker and hillock on Cu/Ni/SnAg micro-bumps under high temperature and humidity storage

open access: yesMaterials Letters: X, 2021
It is the first time that tin whisker was observed to grow from shallow surface grains on Cu/Ni/SnAg micro-bumps under high temperature and humidity storage.

The effect of whisker movement on radial distance estimation: a case study in comparative robotics

open access: yesFrontiers in Neurorobotics, 2013
Whisker movement has been shown to be under active control in certain specialist animals such as rats and mice. Though this whisker movement is well characterised, the role and effect of this movement on subsequent sensing is poorly understood.

Functional analysis of ultra high information rates conveyed by rat vibrissal primary afferents

open access: yesFrontiers in Neural Circuits, 2013
Sensory receptors determine the type and the quantity of information available for perception. Here, we quantified and characterized the information transferred by primary afferents in the rat whisker system using neural system identification ...
