In vivo cranial bone strain and bite force in the agamid lizard Uromastyx geyri [PDF]

open access: yes, 2014
In vivo bone strain data are the most direct evidence of deformation and strain regimes in the vertebrate cranium during feeding and can provide important insights into skull morphology.

Pyrophosphate‐Containing Calcium Phosphates Negatively Impact Heterotopic Bone Quality

open access: yesAdvanced Healthcare Materials, EarlyView.
The role of calcium pyrophosphate (Ca‐PP) in heterotopic bone formation and material degradation is investigated using calcium phosphate (CaP) compositions with varying Ca‐PP content. Results show that Ca‐PP does not impede heterotopic bone formation, minimally affects CaP degradation at non‐osseous sites, and increases phagocytosis.

A Wireless Cortical Surface Implant for Diagnosing and Alleviating Parkinson's Disease Symptoms in Freely Moving Animals

open access: yesAdvanced Healthcare Materials, EarlyView.
A wireless cortical surface implant employing graphene electrode arrays diagnoses and alleviates Parkinson's disease symptoms in freely moving animals. The device continuously monitors cortical activity and delivers targeted stimulation, restoring beta–gamma and delta oscillations.

Bayesian Modelling of Skull Conductivity Uncertainties in EEG Source Imaging

open access: yes, 2017
Knowing the correct skull conductivity is crucial for the accuracy of EEG source imaging, but unfortunately, its true value, which is inter- and intra-individually varying, is difficult to determine.

Multifunctional Neural Probes Enable Bidirectional Electrical, Optical, and Chemical Recording and Stimulation In Vivo

open access: yesAdvanced Materials, EarlyView.
Convergence drawing is used to create flexible, microscale, multifunctional fiber‐based neural probes. Optimized materials selection enables individual devices to perform neural recording, electrical stimulation, optogenetics, fiber photometry, fluid delivery, and voltammetric neurotransmitter detection in rodents.

Production of single-domain magnetite throughout life by sockeye salmon, Oncorhynchus nerka [PDF]

open access: yes, 1988
Although single-domain particles of biogenic magnetite have been found in different species of pelagic fishes, nothing is known about when it is synthesized, or about whether the time during life when it is produced is correlated with the development of

Head phantoms for electroencephalography and transcranial electric stimulation: a skull material study

open access: yes, 2018
Physical head phantoms allow assessing source reconstruction procedures in electroencephalography and electrical stimulation profiles during transcranial electric stimulation. Volume conduction in the head is strongly influenced by the skull representing

Thermal Processing Creates Water‐Stable PEDOT:PSS Films for Bioelectronics

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
Instead of using chemical cross–linkers, it is shown that PEDOT:PSS thin films for bioelectronics become water‐stable after a simple heat treatment. The heat treatment is compatible with a range of rigid and elastomeric substrates and films are stable in vivo for >20 days.

Prediction and near-field observation of skull-guided acoustic waves

open access: yes, 2016
Ultrasound waves propagating in water or soft biological tissue are strongly reflected when encountering the skull, which limits the use of ultrasound-based techniques in transcranial imaging and therapeutic applications.
