Tags: TMS, brain-mapping, methods, tier-1

Bayesian structured TMS motor mapping improves anatomical precision vs independent vertex-wise maps—better non-invasive localization of muscle representations for targeting and planning. JNE methods for NIBS mapping.

  • BaMS3 (Bayesian Motor Mapping with Structured Inference) is a TMS motor-mapping method published in the Journal of Neural Engineering for localizing cortical muscle representations from motor evoked potentials (MEPs).
  • Conventional vertex-wise TMS mapping treats cortical locations independently and ignores spatial interactions across the cortical surface.
  • Standard approaches also omit non-linear recruitment dynamics and trial-to-trial MEP noise, which degrades map quality.
  • Those limitations reduce spatial precision most in anatomically complex, folded cortex.
  • BaMS3 replaces independent vertex-wise maps with Bayesian structured inference that models spatial structure and recruitment/noise jointly.
  • The method aims to improve non-invasive localization of muscle representations for TMS targeting and planning.

Computational stability/sensitivity of effort-dependent contralaterally controlled FES for stroke hand assistance—neuroprosthetic control design without volitional effort collapse. JNE model study for FES/neurorehab interfaces.

  • A Journal of Neural Engineering computational model analyzes stability and sensitivity of effort-dependent contralaterally controlled functional electrical stimulation (CCFES) for simulated post-stroke hemiplegic hand assistance.
  • CCFES is an emerging intervention with evidence of better post-stroke hand hemiplegia therapy outcomes than cyclic stimulation, including hand dexterity.
  • In CCFES, the amount of paretic hand opening assistance is controlled by how much the non-paretic hand opens.
  • That contralateral mapping lets CCFES assist paretic hand opening during task practice rather than only delivering fixed cyclic stimulation.
  • Current CCFES techniques do not stop participants from reducing volitional effort while receiving assistance.
  • The modeled effort-dependent CCFES design targets neuroprosthetic control that remains stable and sensitive under assisted hemiplegic hand use.

WIRED clinical feature on noninvasive focused ultrasound modulating brain circuits for meth addiction—adjacent neuromodulation/neurotech with device and outcomes angle, though not a named BCI company milestone.

  • A WIRED clinical feature describes a woman whose meth addiction was so severe that brain surgery was among the last remaining options.
  • Instead of surgery, she received a single session of noninvasive focused ultrasound aimed at modulating brain circuits.
  • That one ultrasound session appeared to achieve what years of prior treatment had not.
  • The approach is framed as sound-based neuromodulation—fixing the brain without a scalpel—rather than an implanted BCI.

Theta-band EEG source connectivity trajectories in Tourette vs typical development—solid clinical neurophysiology time-series methods. Secondary for BCI execution but useful EEG network analysis reference not an interface or decoder study.

  • Typical brain network maturation involves increases in network flexibility and hemispheric specialization.
  • Tourette syndrome (TS) disrupts these developmental trajectories, with tic severity potentially modulating how far networks deviate from typical paths.
  • The study compared theta-band EEG source connectivity states in typically developing children and children with TS.
  • Age-related trajectories and tic-severity effects were tested with generalized linear models that accounted for sex and multiple comparisons.
  • K-means clustering was used to identify dynamic EEG connectivity states from the source-level theta-band network data.
  • The preprint frames dynamic brain network organization as a developmental process that is measurably altered in pediatric Tourette syndrome.

Seeks generalizable spectrotemporal signatures distinguishing driving vs modulatory circuits across cortical/subcortical networks—methods signal for interpreting stimulation and recording engagement beyond single regions.

  • Frontiers in Human Neuroscience examines spectrotemporal signatures that distinguish driving versus modulatory circuits across cortical and subcortical networks.
  • Sensory processing depends on interactions between neural circuits that both convey and regulate information across those networks.
  • Classical frameworks define driving inputs as those that transmit sensory content via suprathreshold activation.
  • Modulatory inputs are defined as those that alter neuronal excitability without directly eliciting spiking.
  • Physiological signatures of driving versus modulatory circuit types that generalize widely across distributed brain regions remain unclear.
  • The work targets generalizable spectrotemporal markers of circuit type to support interpreting stimulation and recording engagement beyond single regions.

Population-dynamics model of cortico-cerebellar preparatory motor activity under optimal control—useful context for motor BCI decoding of prep states and learning. Computational, not device/trial data watchlist.

  • Researchers introduce a sensorimotor learning framework for a cortico-cerebellar network grounded in population dynamics.
  • The model applies optimal control theory to how preparatory motor activity is refined before movement.
  • In the framework, a cerebellum model boosts preparatory activity via premotor input so motor cortex can reach desired movement initial conditions more efficiently.
  • The paradigm focuses on automatization of already executable behaviors rather than acquiring new motor skills.
  • The work is a computational cortico-cerebellar network model posted as a bioRxiv Neuroscience preprint on refining preparatory activity in motor control.

NHP work combines cortical EEG with basal ganglia–thalamic unit activity REM disengages pathological beta, enabling rapid dream movements despite daytime bradykinesia. Strong invasive electrophysiology and state-dependent beta methods for closed-loop DBS/BCI. bioRxiv preprint. .

  • REM sleep behavior disorder is a hallmark of prodromal α-synucleinopathies, yet why people with Parkinson’s disease can make rapid, coordinated movements in REM despite daytime bradykinesia has been unclear.
  • Researchers recorded eye movements, cortical EEG, and basal ganglia–thalamic neuronal activity across vigilance states in non-human primates before and after MPTP-induced parkinsonism.
  • MPTP parkinsonism enhanced pathological β oscillations and impaired waking movement, matching the daytime motor phenotype.
  • During REM sleep, β oscillations disengaged from the basal ganglia–thalamic circuit even after parkinsonism was induced.
  • That REM-state β disengagement coincided with rapid dream-related movements that were not available during waking bradykinesia.
  • The work ties a classic REM sleep behavior phenomenology to invasive, state-dependent electrophysiology spanning cortex and deep nuclei.
  • Findings support state-aware β targeting as a mechanistic basis for closed-loop deep brain stimulation and related BCI approaches in parkinsonism.
  • The report is a bioRxiv Neuroscience preprint (doi: 10.64898/2026.08.10.743926).
