An article presented in Science on October 13, 2022 entitled “In Vivo Direct Imaging of Neuronal Activity at High Temporospatial Resolution” has exciting implications for understanding neural transmissions. Phan Tan Toi and coworkers applied “a two-dimensional fast line-scan approach in mice that enables direct imaging of neuronal activity with millisecond precision while retaining the high spatial resolution of magnetic resonance imaging . . . spike recording and optogenetics confirmed the high correlation of the observed MRI signal with neural activity” resulting from electrical whisker-pad stimulation. Their method also “captured the propagation of neuronal activity along the thalamocortical pathway.” the detection of sequential propagation of neuronal activity through functionally defined networks is thus considered possible by the authors.
AS this methodology is developed and applied, it may be possible in the future to track neural transmission in response to the cognitive activity of intent and will and perception, confirming dualist interaction between the immaterial mind and the material synaptic networks of the brain. As I scan the neuroscience literature, I will post such studies if found on my blog site.
