High precision animal stereotaxis with 3D polychromic photogrammetry

This paper introduces a photogrammetry-based platform for automated small animal stereotaxic surgery, improving targeting accuracy and surgical speed through high-resolution 3D skull reconstructions.

Computational model for synthesizing auditory brainstem responses to assess neuronal alterations in aging and autistic animal models

The paper develops a computational model to synthesize auditory brainstem responses (ABRs) and links ABR morphology changes to neuronal alterations in aging and autism animal models.

In-vivo optogenetic manipulation approach for gerbil medial nucleus of trapezoid body

This study develops an in-vivo optogenetic method to control MNTB activity in gerbils with fast and precise temporal control, enabling research on sound localization.

Sapphire-Based Optrode for Low Noise Neural Recording and Optogenetic Manipulation

This paper introduces a sapphire-based optrode that combines high-intensity LED optogenetic stimulation with low-noise neural recording, demonstrating its effectiveness in vivo.

Hearing Ability of Prairie Voles (Microtus ochrogaster)

This study measures hearing ability in prairie voles, finding sex-specific differences in monaural hearing but not binaural hearing or morphology.

Multichannel neural spike sorting with spike reduction and positional feature

The paper introduces GEMsort, a multichannel neural spike sorting algorithm that reduces data volume and improves sorting speed using signal processing modifications.

Predicting the Influence of Axon Myelination on Sound Localization Precision Using a Spiking Neural Network Model of Auditory Brainstem

This study uses a spiking neural network model to show that axon myelination thickness affects ITD detection in the auditory brainstem, with optimal sensitivity achieved through contralateral inhibition via thicker myelinated axons.
