Abstract
Article accompanying a poster presentation for the 2014 Annual Computational Neuroscience Meeting. This article discusses optical imaging of prefrontal cortex hemodynamic response in executive function induced by increased cardiovascular activity.
Highlights
Recent experimental evidence has suggested that an increase in cardiovascular activity resulted from physical exercise can improve cognitive function [1]
We have demonstrated that optical imaging using near-infrared spectroscopy (NIRS) can detect neurohemodynamic responses as well as neural activation and deactivation patterns in the motor cortex [3,4]
This reduction of oxy-hemoglobin supply to the neural tissue could be misinterpreted as neural deactivation by fMRI, which only detects deoxy-hemoglobin level, whereas fNIRS can detect both oxyand deoxy-hemoglobin levels
Summary
Recent experimental evidence has suggested that an increase in cardiovascular activity resulted from physical exercise can improve cognitive function [1]. Cognitive functions are related to oxygen delivery and/or oxygen demand. We have demonstrated that optical imaging using NIRS can detect neurohemodynamic responses as well as neural activation and deactivation patterns in the motor cortex [3,4].
