Diffusion MRI Connections in the Octopus Brain

Abstract: Using high angle resolution diffusion magnetic resonance imaging (HARDI) with fiber tractography analysis we map out a meso-scale connectome of the Octopus bimaculoides brain. The brain of this cephalopod has a qualitatively different organization than that of vertebrates, yet it exhibits complex behavior, an elaborate sensory system and high cognitive abilities. Over the last 60 years wide ranging and detailed studies of octopus brain anatomy have been undertaken, including classical hi… Show more

“…Scientists use neurophysiological methods and modern imaging techniques for a better understanding of neurological procedures and the connection of the different brain sections [18], [19], [20], [21], [22]. A recently developed technique allows the recording of the brain's electrical activity from implanted electrodes in freely moving octopuses [23].…”

“…Studies of the organization and function of the cephalopod nervous system have been ongoing for almost 80 years [1][2][3][4][5][6][7][8][9] , and its value as a comparative model of an independently evolved, complex nervous system is widely recognized 10,11 . Although there is a wealth of information from older studies about the gross structure and organization of the nervous system 12 , and a more recent explosion of molecular and genomic studies of the brain, arms and sensory structures [13][14][15][16][17] , functional characterization of neuronal subtypes and their network organization have remained elusive.…”
