👋 Introducing the BrainStem Bundle Tool or BSBT!
Researchers at the @picowerinstitute.bsky.social have made a publicly available AI algorithm that enables tracking of its vital white matter pathways in the #brainstem: https://bit.ly/4kIYkZB
Highlights
#Medsky🧪 #neurosky #IDSky #publichealth Emerging research and hypotheses suggest that #brainstem dysfunction may be a potential etiology for both ME/CFS & #longCOVID, with some evidences pointing towards a mechanical basis in certain patient subsets

Paper alert!
I’m very pleased to announce the publication of my PhD work, which I carried out under the amazing supervision of Clément Menuet at @inmed.bsky.social

Subcortical sound encoding is not affected by selective attention, while cortical sound encoding is. Top left: The CAP to the attended (red) and unattended (black) speech for the 12 subjects with the eardrum electrode. Bottom left: The ABR for all 28 subjects when attended (red) or unattended (black). No significant differences were observed between conditions for either the CAP or ABR. Shaded regions represent SEM. Right: Cortical responses to attended (top) and unattended (middle) stimuli. Bottom right: The difference waveform and scalp topographies at the selected time points. Asterisks indicate the electrodes that were significantly different across conditions at that time.
How does attention shape #AuditoryProcessing? This study shows that #attention enhances sound encoding only at the cortical level, not in #auditory periphery or #brainstem, so humans’ ability to focus on a single voice in noise relies on cortical mechanisms @plosbiology.org 🧪 plos.io/4pY5L1f

Transient conductive hearing loss (CHL) during development. Top left: Schematic of coronal section of a guinea pig skull (traced from high-resolution CT scan). A custom-made earplug is fitted within the cartilaginous ear canal (dotted line), a safe distance from the tympanic membrane (TM). Inset: View of external ear with earplug in place. Top right: Earplugs provide 10–35 dB SPL sound attenuation for frequencies >1 kHz. Bottom: Experimental timeline. Litters of newborn guinea pigs were divided into two groups at hearing onset (birth): pups that were raised with no earplug (littermate Controls) and pups that were raised with a unilateral earplug (“Early CHL”). Earplugs remained in place until adulthood (P56). Following earplug removal, animals were tested on: auditory brainstem responses (ABRs) including the binaural interaction component (BIC), a startle-based spatial discrimination task, and in vivo single-unit recordings in the auditory midbrain (i.e., inferior colliculus, IC). All testing was done within 1 week of earplug removal.
Early unilateral auditory deprivation can cause lasting spatial #hearing deficits. @anbuhlk.bsky.social &co show that unilateral #HearingLoss during development (but not adult-onset) impairs binaural #brainstem function & spatial hearing acuity in guinea pigs @plosbiology.org 🧪 plos.io/46njw1P

A regular spiking neuron (sustained chopper) that exhibits accurate identification of envelope frequency from its spike trains. Top left: peristimulus time histogram of the response to a pure tone at the characteristic frequency of the neuron. Bottom left: Spike train classifier decisions represented as a confusion matrix. Warm colors along the diagonal indicate a large proportion of individual spike trains were assigned to the correct modulation frequency. Right: Raster plots of the responses to amplitude-modulated tones, for several modulation frequencies (stimulus waveforms displayed above each panel). The number of spikes in each stimulus period decreases as the modulation frequency is increased.
Slow amplitude fluctuations in sounds, critical for #SpeechRecognition, seem poorly represented in the #brainstem. This study shows that overlooked intricacies of #SpikeTiming represent these fluctuations, reconciling low-level neural processing with #perception @plosbiology.org 🧪 plos.io/3FJ4adI
