Appropriation of Perceptual Prostheses: An Enactive Approach to Spatial Perception
This chapter presents an analysis of the mechanisms of perception through perceptual prostheses. Using minimalist devices, we gain a better understanding of possible explanations for the appropriation of the prosthesis and the type of perception it affords. In...

Disentangling the functional roles of pre-stimulus oscillations in crossmodal associative memory formation via sensory entrainment - Scientific Reports
The state of neural dynamics prior to the presentation of an external stimulus significantly influences its subsequent processing. This neural preparatory mechanism might be of particular importance for crossmodal memory formation. The integration of stimuli across different sensory modalities is a fundamental mechanism underlying the formation of episodic memories. However, the causal role of pre-stimulus neural activity in this process remains largely unclear. In this preregistered study, we …

Orbitofrontal cortex drives predictive filtering of sensory responses (in mice) https://www.nature.com/articles/s41593-026-02217-z "After daily sound exposure, neural habituation in the primary auditory cortex (A1) was reversed by inactivating the OFC."

Orbitofrontal cortex drives predictive filtering of sensory responses - Nature Neuroscience
Top-down projections from the orbitofrontal cortex carry predictive signals that grow with sound experience and suppress the auditory cortex via inhibitory circuits, revealing a predictive mechanism for sensory habituation.

Calibrated simulations for dynamic focusing of ultrasound through the temporal window #ultrasound

Calibrated simulations for dynamic focusing of ultrasound through the temporal window
Focused ultrasound can be delivered through the temporal window to modulate heterogeneously located brain areas. Acoustic simulations allow for safety assessments when dynamically targeting brain structures, but the mismatch between simulation and measured focal pressure can vary across the steerable range due to mechanically inaccurate assumptions made about the skull and transducer. Here, we describe efficient methods for simulation-measurement calibration using axisymmetric projections and s…
