Insulotaxy: Navigating the Human Insula with a Novel Stereotactic Framework

This paper introduces a novel stereotactic coordinate system for the insula to improve surgical targeting and outcome assessment by accounting for individual anatomical variability.

Parameterization of intraoperative human microelectroderecordings: Linking action potential morphology to brainanatomy

The paper introduces a method to parameterize and cluster single-unit action potentials from DBS microelectrode recordings to improve lead placement in deep brain stimulation.

The Human Insula Encodes Somatotopic Representation of Motor Execution with an Effector-Specific Connectomic Map to Primary Motor Cortex

The paper maps motor execution representation in the human insula, showing somatotopic organization and effector-specific connectivity to primary motor cortex.

Spatial and Spectral Changes in Cortical Surface Potentials during Pinching versus Thumb and Index Finger Flexion

The paper analyzes ECoG signals during different hand movements to understand cortical activity patterns and their spatial overlap, finding that pinching shows higher overlap with index finger flexion.

Chronic modulation of human memory and thalamic-hippocampal theta activities.

The paper describes a system for chronic stimulation and recording of thalamic-hippocampal theta activities in humans during memory tasks, showing their correlation with memory performance and modulation by deep brain stimulation.

Homunculus Interruptus: A motor association area in the depth of the central sulcus

The paper identifies a motor association area in the central sulcus that interrupts the topological map of body movements generated by the precentral gyrus.
