IN THE SPOTLIGHT

November 2017

 

The year 2015 marked the largest increase in traffic fatalities in the past 50 years, rising 7.2% compared to 2014 and reversing a trend that had been decreasing for decades. Initial 2016 numbers look worse. One potential contributing cause is an upswing in distractions centered around smartphone usage. While researchers have studied activities like texting and phone conversations (shown to negatively affect driving safety and performance), there are still open questions about the cognitive effects of many common driver-device interactions that don’t necessarily involve explicit typing.

To investigate these interactions, we conducted a study where the participant drives through city and highway settings while engaging with a smartphone that presents different levels of distraction, ranging from navigational notifications to full text messaging. During the experiment, we measured neural activity, heart rate, head movement, pupil diameter, and gaze location, as well as measures of the participant’s driving patterns and phone usage. Analysis of these data will help us to better understand the physiological resources involved in different levels of smartphone engagement while driving and how these distractions affect a person’s driving behavior.

The Science of Cooperation: Brain Scans Show Different Activity In Men And Women When Working Together

New research shows that the males and females have different patterns of brain activity when engaging in cooperative behavior. Senior author Allan Reiss, professor of psychiatry and behavioral sciences, is quoted here and in articles from Live ScienceMedical Daily,Quartz, and Talk Media News.  Lead author Dr. Joseph Baker was also interviewed on BBC World Service News on whether or not men work better with other men.

Can Cycling and Exercise Create a Better Future for Children with ADHD?

Stanford research, with support from the Specialized Foundation, aims to better understand effects of exercise on brain function and cognition in children with ADHD. Link to Press Release

May 2016

Congratulations to Dr. Hadi Hosseini for obtaining a K25 Mentored Quantitative Research Development Award from the National Insitiute of Aging. Dr. Hosseini will use the award to develop integrated computational techniques and multimodal neuroimaging methods, to study the effects of long-term multi-domain cognitive training on large-scale structural and functional brain networks in mild cognitive impairment (MCI), a risk factor for Alzheimer's disease (AD).

October 2015

Drs. Allan Reiss and Manish Saggar received another year of funding from Hasso Plattner Institute to explore using NIRS in real-life settings. The proposal aims to assess the behavioral and neural signatures of dyadic interactions in the d.school setting itself, while design thinkers are engaged in problem solving and creative thinking. Using an adapted version of the tasks previously established in this project, we will prototype and establish the feasibility of performing functional neuroimaging in real-world settings.

August 2015

Dr. Hosseini has recieved a NARSAD and CHRI grant.  These grants focus on "Integrating NIRS-based neurofeedback and cognitive rehabilitation for improving executive function (EF) network in patients with attention deficit hyperactivity disorder (ADHD)".  The proposed intervention would be the first that integrates real time functional imaging feedback (neurofeedback) – using near infrared spectroscopy (NIRS) – with computerized cognitive rehabilitation in order to improve individualized neural systems underlying EF in children with ADHD. The proposed pathology-focused intervention has the potential to be generalized for improving executive function in patients with significant EF deficits including children with autism spectrum disorder and traumatic brain injury.

April 2015

Dr. Manish Saggar received the prestigious Career Development Award (K99/R00) from the National Institute of Mental Health. This award helps outstanding postdoctoral researchers complete needed mentored training and transition in a timely manner to independent, tenure-track or equivalent faculty positions. Dr. Saggar will use this award to develop individualized metrics and computational models to capture the dynamics of brain activity at rest (using fMRI and NIRS), so that disorder-specific biomarkers can be developed for early detection and treatment of mental illnesses.
