Precise Timing Matters: Modulating Human Memory by Synchronizing Hippocampal Stimulation to Saccadic Event Related Potentials

This study shows that precise hippocampal stimulation timed to saccadic ERPs enhances memory, while random or early stimulation impairs it, challenging rodent theta rhythm assumptions.

Phase resetting in human auditory cortex to visual speech

The paper investigates how visual speech influences auditory cortex activity through phase resetting of neuronal oscillations during audiovisual speech processing.

Differential generation of saccade, fixation and image onset event-related potentials in the human mesial temporal lobe

The paper compares ERP responses in the human mesial temporal lobe to saccades, fixations, and image onset during a visual memory task, finding distinct mechanisms for each.

Deep Convolutional modeling of human face selective columns reveals their role in pictorial face representation

The paper shows that face-selective brain columns match deep convolutional networks in intermediate layers, suggesting a role in pictorial face representation rather than person identification.

Repeated performance in problem-solving tasks attenuates human cortical responses

This study shows that repeated performance in complex visual problem-solving tasks leads to reduced cortical responses in specific brain regions, but not changes in response time.

Increasing suppression of saccade-related transients along the human visual hierarchy

The paper shows that saccade-related transients are suppressed in higher-level visual cortex but not early visual cortex in humans.

iELVis: An open source MATLAB toolbox for localizing and visualizing human intracranial electrode data

iELVis localizes and visualizes intracranial electrodes using MRI and neuroimaging tools, providing accurate brain shift correction and interactive 3D/2D visualization with functional overlays.
