Ultrasonographic measurements of fascicle length overestimate adaptations in serial sarcomere number

open access: yesExperimental Physiology, 2023
Ultrasound‐derived measurements of muscle fascicle length (FL) are often used to infer increases (chronic stretch or training) or decreases (muscle disuse or aging) in serial sarcomere number (SSN).

Machine learning to extract muscle fascicle length changes from dynamic ultrasound images in real-time

open access: yesbioRxiv, 2021
Background and objective Dynamic muscle fascicle length measurements through B-mode ultrasound have become popular for the non-invasive physiological insights they provide regarding musculoskeletal structure-function. However, current practices typically

Do triceps surae muscle dynamics govern non-uniform Achilles tendon deformations? [PDF]

open access: yesPeerJ, 2018
The human Achilles tendon (AT) consists of sub-tendons arising from the gastrocnemius and soleus muscles that exhibit non-uniform tissue displacements thought to facilitate some independent actuation.

Combined DTI Tractography and Functional MRI Study of the Language Connectome in Healthy Volunteers: Extensive Mapping of White Matter Fascicles and Cortical Activations. [PDF]

open access: yesPLoS ONE, 2016
Despite a better understanding of brain language organization into large-scale cortical networks, the underlying white matter (WM) connectivity is still not mastered.

The capillary fascicle in skeletal muscle: Structural and functional physiology of RBC distribution in capillary networks

open access: yesJournal of Physiology, 2021
The capillary module, consisting of parallel capillaries from arteriole to venule, is classically considered as the building block of complex capillary networks.

Maximal fascicle shortening velocity measurements in human medial gastrocnemius muscle in vivo

open access: yesPhysiological Reports, 2023
This study evaluated the maximal fascicle shortening velocity under near‐no‐load conditions. In addition, we determined whether the rate of torque development during ballistic contraction was related to maximal fascicle shortening velocity. Under passive

Does different activation between the medial and the lateral gastrocnemius during walking translate into different fascicle behavior?

open access: yesJournal of Experimental Biology, 2021
The functional difference between the medial gastrocnemius (MG) and lateral gastrocnemius (LG) during walking in humans has not yet been fully established.

Endoneural selective stimulating using wire-microelectrode arrays [PDF]

open access: yes, 1999
In acute experiments eight 5- to 24-wire-microelectrode arrays were inserted into the common peroneal nerve of the rat, to investigate whether the electrodes could selectively stimulate motor units of the extensor digitorum longus (EDL) muscle.

A ketogenic supplement improves white matter energy supply and processing speed in mild cognitive impairment

open access: yesAlzheimer’s & Dementia: Translational Research & Clinical Interventions, 2021
Introduction White matter (WM) energy supply is crucial for axonal function and myelin maintenance. An exogenous source of ketones, the brain's alternative fuel to glucose, bypasses the brain's glucose‐specific energy deficit and improves cognitive ...
