The Right Temporoparietal Junction Supports Speech Tracking During Selective Listening: Evidence from Concurrent EEG-fMRI

NataTech Citations in Research

fMRI data were acquired on a 3 T Siemens MAGNETOM Verio MRI scanner with a 12-channel head array. Key presses were recorded using an MR-compatible response keypad (Nata Technologies). Acoustic stimuli were delivered via MR-compatible insert earphones (MR confon HP AT01; MR Confon). Participants were equipped with over-ear hearing protectors during the experiment to attenuate…

The Brain Is Faster than the Hand in Split-Second Intentions to Respond to an Impending Hazard: A Simulation of Neuroadaptive Automation to Speed Recovery to Perturbation in Flight Attitude

NataTech Citations in Research

Experimental Tasks Two different tasks were used, a simple piloting task of level flight over the ocean and a more complex piloting task through the Grand Canyon. We used the first task to develop a method for decoding of neural states associated with response to a perturbation and the second task to investigate the generalizability…

Activation in human auditory cortex in relation to the loudness and unpleasantness of low-frequency and infrasound stimuli

NataTech Citations in Research

The fMRI measurements were done on a 3-T scanner (Magnetom Prisma 3T, Siemens AG, Erlangen, Germany), equipped with a 20-channel head coil. The response scale and a fixation cross (see below) were projected onto a screen in the scanner bore and could be seen by the participants via a mirror construction mounted onto the head…

Neural signatures of experimentally induced flow experiences identified in a typical fMRI block design with BOLD imaging

NataTech Citations in Research

The present experimental design resembled that of our previous study (Ulrich et al., 2014). Major changes, however, applied to the length and number of blocks to meet the requirements imposed by the experimental realization as an fMRI block design to measure the blood oxygen level-dependent (BOLD) signal. Subjects performed visually presented mental arithmetic tasks. On each trial,…

Unmasking selective path integration deficits in Alzheimer’s disease risk carriers

NataTech Citations in Research

Participants navigated the virtual environments using a joystick (behavioral experiment, Trust GXT 555 Predator; fMRI experiment, MR-compatible joystick from Nata Technologies, Coquitlam, Canada), allowing them to move forward, turn left, or turn right. Moving backward was not possible so that movement direction was equivalent with heading direction. In each subtask, participants’ speed was attenuated when…

Diet modulates brain network stability, a biomarker for brain aging, in young adults

NataTech Citations in Research

To assess whether effects extended beyond resting state to tasks that increased cognitive load and therefore brain metabolic demand, for the diet study and case study, participants additionally navigated virtual reality mazes using an MR-compatible joystick (Nata Technologies). We created these mazes using the Aldous–Broder algorithm in Daedalus (https://www.astrolog.org/labyrnth/daedalus.htm) and programmed them for a virtual…

Navigating through digital folders uses the same brain structures as real world navigation

NataTech Citations in Research

The fMRI session took place the next day. The participant’s laptop was connected to a high-resolution LCD screen in the scanner room. The screen was visible to the participant in the scanner via a mirror positioned at the top of the radiofrequency head coil. Participants interacted with their laptop using an MRI-compatible optical mouse (NAtA…
